Separate Port 24V 60A bms protection circuit module lifepo4 battery BMS 8S
About the battery BMS/PCB/PCM Function:
- Detect and protect the battery from over-charge ;over-dicharge, over-current ,
- Short-circuit ,temperature detecting protection and auotmatically voltage balance function .
Advantage:
- Use top quality (A-level) protective integrated circuit IC, from the solution of Seiko of Japan.
- Strong load ability, constant discharge current 10A/25/35A/45A/60A/100A/200A/350A , use high voltage resistance, low innerresistance power Mosfet. The heat sink will greatly help cooling.
- IC itself has power balancing function. The circuit is simple and reliable.
- Typical voltage detection for each cell. So each battery will be prevented over charged or over discharged. Over current and short circuit protection function is very reliable.Long time short circuit of the load won’t affect the PCB and the battery.Temperature protection during charging and discharging.
- Extreme low power consumption. The consumption of the whole device is less than 50uA.
- PCB use high anti-corrosion, high water resistance, high impedance ESD conformal Coating.

Q: How many Ampere protection circuit boards should choose?
A: It depends on your load power such as electric motor power please contact the sales or technical support before buying.
Q: What is the distinction between same port wiring and different port wiring?
A: The cathode of charger and load is different for different port wiring , the cathode of charger and load is same for same port wiring and the charging current is equal to the discharge current.
Q: What is the distinction between balance and unbalance function?
A: Equilibrium function is that high voltage cells will be discharged with resistor, waiting for the low voltage cells , to achieve the each cell voltage is consistent , to improve the battery performance for the whole group.
Q: Do you have Minimum Order Requirement (MOQ)?
A: No, We don’t have MOQ, Different customer have different requirement ,We can provide various capacity and size is per your requirements,Also ODM / OEM is welcome.
Q: What is your term of payment?
A: PayPal, T/T, L/C,
