Actually the main reason we went with this one is the BMS integration is pretty much complete — three-stage protection plus active balancing built into a single board, which saves a lot of wiring headache when you're assembling a rack.
Nominal 48V at 50Ah gives you about 2.4kWh usable, which is decent for mid-size storage setups, and teh max continuous current is 50A so it'll handle a 2,400W draw continuous without sweating, though we'll likely see brief peaks higher than that.
it support SMBus, I2C, RS232, RS485, and Bluetooth — so you can talk to it from basically any controller you'd run in a lab or field setup, and Bluetooth app works for quick checks (usually within 10 meters range or so).
The real detail most people miss is the SoC reporting accuracy: it maintains about 3% error across -10°C to 50°C, which is tighter tolerance than most generic packs we've tested, but if your enviroment runs below -20°C you'll want to add a heater circuit because the BMS will just shut down discharge.
Lead time form Shenzhen is typically 18-22 working days after payment, and they'll send COA with every batch — we usually have stock for samples, but confirm before ordering if you're on a tight schedule.
One thing to note: the plastic case is fine for stationary storage but I wouldn't use it in an RC boat unless you seal the connectors well; moisture ingress is a known issue with their standard housing.
The max continuous working current is 50A, so you can draw up to that continuously without tripping the BMS. For short bursts, the BMS may handle higher peaks, but 50A is the safe continuous limit.
Yes, we can configure it with either common or separate ports depending on your application. Just let us know which setup you need when placing the order.
The BMS supports SMBus, I2C, RS232, RS485, and Bluetooth, so you have plenty of options for real-time data access. Bluetooth is handy for mobile monitoring; serial interfaces work well for integration into larger systems.
We can supply UN38.3, MSDS, and CE test reports upon request. Since it's a LiFePO4 pack, it's safe for air and sea shipping with proper documentation.
Our MOQ for factory direct orders is typically 10 units, but we can be flexible for first-time buyers or sample orders. Contact us with your quantity to confirm lead time and pricing.
