Li-ion battery BMS 48V 40A 14 series 48V battery pack.
The Li-ion battery BMS 48V 40A (lithium-ion 18650 Battery Management System).functions are overcharge protection, over-discharge protection, over current protection, short-circuit protection, temperature protection, etc.
According to the customer’s request, we can develop PCM in different sizes and structures. BMS manufactured by high-quality Mos and IC imported. Keep your battery long cycle service lifetime. resistance power Mosfet. The heat sink will greatly help to cool.IC itself has a power balancing function. The circuit is simple and reliable.
Common voltage discovery for every cell. So every battery will be forestalled overcharged or over-released. Over-current and short-out assurance work is entirely solid. A long time short out of the heap won’t influence the PCB and the battery. The utilization of the entire gadget is under 50uA.PCB utilizes high enemy of consumption, high water opposition, high impedance ESD conformal Coating.
This Li-ion battery BMS is comparable to LI iON (NMC)battery pack.
