New Panda 32kWh & 48kWh LiFePO4 Battery Packs: DAREN BMS Inside
What’s New: DAREN Smart BMS Replaces Kesheng
Every Panda pack built before this batch used a Kesheng (KS) BMS. The new Panda 32kWh moves to a DAREN 16S 200A smart BMS, and the new Panda 48kWh to a DAREN 16S 300A smart BMS. That is the single biggest technical difference between the old and new Panda batteries — the capacity points, cell platform, cabinet and warranty are unchanged.
| Item | Old Panda | New Panda |
|---|---|---|
| BMS brand | Kesheng (KS) | DAREN |
| Panda 32kWh BMS | Kesheng 16S 200A | DAREN 16S 200A |
| Panda 48kWh BMS | Kesheng 16S 300A | DAREN 16S 300A |
| Cell platform | 3.2V 314Ah LiFePO4, 51.2V 16S | Unchanged |
| Communication | CAN / RS485 | CAN / RS485 |
| Parallel operation between old and new packs | — | Supported, including BMS communication |
Why the switch matters. The BMS is the component that decides how hard the pack can be charged and discharged, how well the cells stay balanced, and whether the inverter can talk to the battery in closed loop. Moving both capacities onto one DAREN platform means the 200A and 300A variants share the same control logic, the same communication stack and the same monitoring app, which simplifies spares, firmware support and commissioning across a mixed fleet. It also puts a purpose-built BMS platform behind a 32- to 48-cell pack instead of a legacy board carried over from earlier batches.
What this means if you already own Panda packs. You do not have to replace anything. New Panda packs and older Kesheng-based Panda packs can be connected in parallel and will communicate with each other, because both generations sit on the same 51.2V 16S architecture and speak the same CAN/RS485 protocol set. The BMS brand difference is not a compatibility barrier — it only means the two generations were built around different control boards.
That said, the rules for a healthy bank still apply: parallel only packs of the same capacity and cell configuration, bring every pack to the same SOC before paralleling, use busbar-based parallel connections once you go beyond four packs, and confirm the inverter protocol against the current compatibility list.
Beyond the BMS, four things define the new Panda packs:
- 314Ah cells in a fixed, documented configuration. The 32kWh uses 32 cells in 16S2P; the 48kWh uses 48 cells in 16S3P. Both are Grade A LiFePO4, and the 32kWh pack currently ships with CALB 314Ah cells.
- 2A active balancing. Active balancing moves charge between cells rather than burning it off as heat, which keeps a 32- to 48-cell pack in tighter balance as it ages.
- Local visibility. A 5-inch touchscreen shows voltage, SOC, current, temperature, cycle count and per-cell status without opening an app.
- Monitoring and inverter comms built in. CAN and RS485 for closed-loop inverter communication, plus WiFi and Bluetooth for the mobile app.
Panda 32kWh vs 48kWh: Specification Comparison
Both are horizontal-cabinet packs for low-voltage (48V-class) hybrid inverters, so the same plant-room layout, cabling approach and inverter family apply to either capacity. The differences are energy, current, weight and footprint.
| Specification | Panda 32kWh | Panda 48kWh |
|---|---|---|
| Nominal voltage | 51.2V | 51.2V |
| Nominal capacity | 628Ah | 942Ah |
| Usable energy (nominal) | 32.15kWh | 48.23kWh |
| Cell configuration | 16S2P (32 × 314Ah) | 16S3P (48 × 314Ah) |
| BMS | DAREN 16S 200A smart BMS | DAREN 16S 300A smart BMS |
| Maximum continuous working current | 200A | 300A |
| Suggested daily operating current (for longest cycle life) | 150A charge / 150A discharge | 200A charge / 200A discharge |
| BMS balancing | 2A active | 2A active |
| Display | 5-inch touchscreen | 5-inch touchscreen |
| Communication | CAN / RS485 / WiFi / Bluetooth | CAN / RS485 / WiFi / Bluetooth |
| Dimensions (L × W × H) | 800 × 430 × 640 mm | 897 × 520 × 760 mm |
| Net weight | 238 kg | 360 kg |
| Ingress protection | IP20 (indoor) | IP20 (indoor) |
| Charge temperature | 0 °C to 45 °C | 0 °C to 55 °C |
| Discharge temperature | −20 °C to 60 °C | −20 °C to 60 °C |
| Warranty | 10 years (assembled pack) | 10 years (assembled pack) |
Two specification notes that matter in practice.
First, the current ratings are real working figures, not peaks. The Panda 48kWh supports up to 300A continuous charge and discharge, and the Panda 32kWh supports up to 200A continuous — both confirmed by Docan engineering for continuous operation, not just short bursts. The lower figures in the table above are the daily operating range we recommend for cycle life, not a hardware ceiling. What still has to be checked on site is the rest of the DC path: cable cross-section, breaker and fuse ratings, inverter power, ambient temperature and installation method all have to be sized for the current you actually intend to run.
Second, cycle life figures are design references, not guarantees. Docan publishes an 8,000+ cycle reference at cell level. Real-world cycles depend on depth of discharge, temperature, charge rate and how the pack is cycled. The 10-year warranty is the document that governs your claim, so read it before sizing.
How Much Backup Does 32kWh or 48kWh Actually Deliver?
Nameplate capacity and usable capacity are different numbers. At a practical 90% depth of discharge:
- Panda 32kWh: roughly 28.9kWh usable
- Panda 48kWh: roughly 43.4kWh usable
Now match that to consumption. The average US household consumes about 10,500 kWh per year, or roughly 29 kWh per day (U.S. Energy Information Administration). European homes vary widely with heating type and climate, but many sit in the 10–15 kWh per day range.
That produces a simple rule of thumb:
| Daily consumption | Panda 32kWh covers | Panda 48kWh covers |
|---|---|---|
| 10 kWh/day | ~2.5–3 days | ~4 days |
| 15 kWh/day | ~2 days | ~2.5–3 days |
| 25–30 kWh/day | ~1 day | ~1.5 days |
These figures assume no solar input and no load management. With a 6–10kW PV array recharging daily, either pack can carry a home through the evening peak indefinitely in most climates — the battery becomes a time-shifting tool rather than a generator replacement.
Which Panda Pack Fits Your Project?
Choose the Panda 32kWh LiFePO4 battery pack if:
- Your inverter is in the 5–8kW range and your critical-load panel is modest
- You want to add storage to an existing PV system without rebuilding the plant room
- Floor space is tight — the cabinet is 800 × 430 × 640 mm and 238 kg, which fits through a standard doorway and can be moved with a pallet truck
- Your grid is stable and the battery’s job is peak shaving and self-consumption, not multi-day outage cover
Choose the Panda 48kWh LiFePO4 battery pack if:
- You are planning whole-home backup, including heat pump or EV charging loads
- Your inverter is 8–12kW and you want headroom for a 300A-class DC path
- You need two to three days of autonomy in a high-consumption house
- You would rather buy one cabinet now than parallel two smaller ones later
Scaling up. Both packs support parallel connection, and the 48kWh is rated for up to 16 units in parallel for larger projects. Mixing generations is allowed: a new DAREN-based pack can join a bank of older Kesheng-based Panda packs, and the units will communicate with each other.
Mixing capacities is not. Docan does not recommend connecting a 32kWh and a 48kWh pack in the same bank. Two different capacities in parallel do not share current in proportion to their size — the smaller pack cycles harder, drifts out of balance with the larger one and ages faster, and the combined bank will not deliver the sum of its parts. Build a bank from packs of the same capacity, bring every pack to the same SOC before paralleling, and switch to busbar-based parallel connection once you go beyond four packs so current sharing stays even.
If you need more energy than one capacity tier gives you, scale within a single tier instead of mixing: two 32kWh units for a 64kWh bank, or two 48kWh units for a 96kWh bank.
If you are weighing the Panda against Docan’s other large-format cabinets, the MOON 48kWh uses a different enclosure and BMS with a touchscreen-first interface, while the Panda 48kWh product page carries the current accessory and cable configuration.
Inverter Compatibility: Check Before You Order
Both Panda packs communicate over CAN and RS485 and are tested against the common low-voltage hybrid inverter families, including Deye, Sunsynk, Victron, Growatt, Sol-Ark, Lux Power/EG4, Sungrow, Solis, GoodWe, Sofar, SMA, MUST, SRNE, Megarevo, Sacolar and Voltronic.
Compatibility is model-, firmware- and configuration-specific — two identical inverters on different firmware can behave differently on the same battery. It is also tied to the BMS generation: the Kesheng-based Panda packs and the new DAREN-based packs are validated against their own compatibility lists, so quote the pack model, BMS generation and inverter model together when you ask. Before ordering, send the inverter brand, exact model and current firmware version so the protocol can be confirmed. If your inverter is not on the list, it can usually still run in voltage mode, but you lose closed-loop control and the associated safety limits.
Installation and Site Planning
A 32–48kWh cabinet is not a plug-in appliance. Plan for the following before delivery:
- Access route. The 48kWh cabinet is 897 × 520 × 760 mm and 360 kg net (386 kg packed). Measure doorways, stair turns and lift dimensions.
- Floor loading. Check the structural rating of the floor or wall where the pack will sit, and keep it out of flood-prone areas.
- Clearance and ventilation. Leave service space at the front panel and around the breaker and terminals.
- DC protection. Cable sizing, breaker, fuse and grounding must match the BMS current limit and the inverter’s DC input, not the marketing capacity.
- Commissioning. Voltage measurement, polarity check, BMS address setting, inverter protocol selection and a first charge cycle should be carried out or verified by a qualified installer under local electrical rules.
The packs are certified to CE, IEC 62619 and UN38.3 for transport — IEC 62619 covers safety of industrial lithium cells and batteries, and UN38.3 governs air transport testing under the UN Model Regulations. Always confirm the certificate set for your destination country at the time of order.
Stock, Delivery and Lead Times
Both capacities are held in Docan’s own overseas warehouses, so there is no factory lead time and no ocean freight on local orders.
| Region | Warehouse | Handling | Door-to-door delivery | Terms |
|---|---|---|---|---|
| EU | Germany | Dispatched within 2 working days | 3–10 days | DDP, truck or parcel carrier; self-pickup available |
| US | Texas | Dispatched within 2 working days | 3–10 days | DDP within the continental US |
Two working days is the handling time to get the pack out of the warehouse; the 3–10 day window covers onward transport to the address. Remote ZIP codes, islands and some special postcodes may take longer or carry a surcharge, and a few fall outside the standard route — confirm before payment. DDP sea shipping from China remains the lower-cost option for larger orders, with 45–60 days transit.
Indicative pricing at the time of writing: the Panda 32kWh starts around US$3,024 (EU) / US$3,054 (US), and the Panda 48kWh around US$4,337 (EU) / US$4,367 (US), excluding tax and delivery. Stock levels and prices move with each batch, so check the live product page or request a quote.
Frequently Asked Questions
What is the main difference between the old Panda and the new Panda?
The BMS. Earlier Panda packs were built with a Kesheng (KS) BMS. The new Panda 32kWh uses a DAREN 16S 200A smart BMS, and the new Panda 48kWh uses a DAREN 16S 300A smart BMS. Capacity, cell type, cabinet dimensions, communication interfaces and the 10-year warranty are unchanged.
Can a new Panda pack be paralleled with an older Kesheng-based Panda pack?
Yes, as long as the capacity is the same. Both generations share the same 51.2V 16S architecture and CAN/RS485 protocol set, so they can be connected in parallel and will communicate with each other. A new 32kWh pack joins a bank of older 32kWh packs; a new 48kWh pack joins a bank of older 48kWh packs. Bring all packs to the same SOC before connecting and confirm the inverter protocol against the current compatibility list.
What is the difference between the Panda 32kWh and 48kWh?
Capacity, current and size. The 32kWh pack is 51.2V / 628Ah (32.15kWh) with a DAREN 16S 200A BMS, 238 kg and an 800 × 430 × 640 mm cabinet. The 48kWh pack is 51.2V / 942Ah (48.23kWh) with a DAREN 16S 300A BMS, 360 kg and an 897 × 520 × 760 mm cabinet. Both use 314Ah LiFePO4 cells, 2A active balancing and the same 5-inch touchscreen.
Are the cells Grade A, and which brand is used?
Yes, both packs use Grade A 314Ah LiFePO4 cells. The 32kWh currently ships with CALB cells. Cell brand can vary between batches on the 48kWh, so confirm the exact configuration in the current batch specification if brand consistency matters for your project.
Can I connect a 32kWh and a 48kWh pack in the same bank?
No — Docan does not recommend it. Parallel only packs of the same capacity and cell configuration. A 32kWh and a 48kWh in one bank will not share current in proportion to their capacity: the smaller pack works harder, drifts out of balance with the larger one and ages faster, so the bank underdelivers and wears unevenly. If 32kWh is not enough, add another 32kWh; if you need more than that, build the bank from 48kWh units. Note that BMS brand is not the constraint — different BMS generations of the same capacity can be mixed, different capacities cannot.
What is the maximum working current of each pack?
The Panda 48kWh supports 300A continuous charge and discharge, and the Panda 32kWh supports 200A continuous. Both are confirmed working figures, not short-term peaks. We suggest running at roughly half of that for daily cycling to maximise cycle life, and the cable, breaker, fuse and inverter on site must all be sized for the current you plan to run.
Will it work with my Deye, Victron, Growatt or Sol-Ark inverter?
Most likely, if the model and firmware are on the current compatibility list. Confirm the exact inverter model and firmware before ordering, because protocol support changes between firmware releases.
How long is the warranty, and what does it cover?
Assembled Panda packs carry a 10-year warranty. Grade A bare cells carry 5 years, and DIY boxes and parts such as BMS units and testers carry 1 year. Warranty terms, including capacity retention thresholds, are set out in the warranty document supplied with the order.
Can the Panda be installed outdoors?
The 32kWh cabinet is IP20 and must be installed indoors in a dry, ventilated space. The 48kWh cabinet is IP55-rated, but it is still a lithium battery cabinet and should be sited under cover, away from direct rain, standing water and direct sun.
The Bottom Line
The new Panda line removes the most common sizing mistake in home storage: buying one cabinet size and hoping it fits the load. The 32kWh covers a typical European home with a 5–8kW inverter; the 48kWh covers whole-home backup, heat pumps and higher-consumption households, with a 300A DC path and room to parallel. Both now run a DAREN 16S smart BMS — 200A and 300A respectively — and both remain parallel- and communication-compatible with earlier Kesheng-based Panda packs, so existing installations can be expanded instead of replaced. Both are in stock in the EU and US, both leave the local warehouse within two working days and arrive door-to-door in 3–10 days, and both carry the same 10-year assembled-pack warranty.
