If you're replacing lead-acid with LiFePO4, the 4S1P arrangement of 3.2V 160Ah cells gives you a direct 12.8V nominal — no need to rewire your system for a different float voltage, though the operating window (10V to 14.4V) means BMS cutoff is tighter than what most lead-acid chargers expect, so verify your charge profile doesn't push above 14.4V or you'll trigger the 160A BMS protection.
Cycle life above 2000 is realistic at 80% depth of discharge, but we usually see about 1800 cycles in field data before capacty drops below 70% — the internal resisance creeps up with temperature cycling, and if you're running it at 55°C ambient continuously, that 2000 number shrinks. The 1.92kWh rated energy storage translates to roughly 93% usable capacity at 0.5C discharge, which is better than reagent grade cells for this application and actually tighter tolerance than most generic prismatic packs.
The communication interface is CC/AC, not CAN bus or RS485, so if your system expects J1939 or Modbus you'll need an adapter — something buyers don't always check before ordering, and it'll add a week to your integration. We stock these in carton boxes, 20kg each, 400x170x228mm, and the MOQ is usually 50 units or so, but confirm lead time because the BMS component sourcing can fluctuate.
What it's not suited for is high-rate pulse discharge above 160A continuous — the BMS will hard cut at 160A plus a 20% surge margin, so don't plan on starting a 3kW inverter without inrush limiting. The 3.2V 160Ah cells are grade A LiFePO4 from a domestic Chinese source, and each batch ships with an HPLC-verified COA showing capacity within 2% of nominal at 25°C.
Storage is straightforward: keep them at 50% state of charge in a dry enviornment below 30°C, and you'll get a shelf life of 12 months before self-discharge drops to about 3% per month — we've seen some units sit 18 months and still pass the 0.5C capacity test within 5% of spec. Also, the CE and IEC62619 certs are valid, but the certification covers the cell level not the pack BMS integration, so if you're selling into a regulated market, double-check your local requirement.
The BMS is rated at 160A continuous, which matches the battery's capacity for high-draw applications like inverters or trolling motors.
Our standard models come with CC/AC communication, but we can adjust the interface to CAN or RS485 for bulk orders—just let us know your protocol requirements.
MOQ is typically 10 units for stock models, but we can start with a sample or smaller batch for first-time buyers.
The LCD shows real-time voltage, capacity, and cycles. WiFi connectivity is optional on this model, so double-check when ordering if you need app monitoring.
Lead time is around 15-20 working days after payment, depending on stock levels. We'll confirm exact timing once we check availability.
