Product Description

Six advantages of BEST BMS
1.Use top quality (A-level) protective integrated circuit IC,from the solution of Seiko of Japan.
2.Strong load ability,use high voltage resistance,low inner resistance power Mosfet.The heat sink will greatly help cooling.
3.IC itself has power balancing function.The circuit is simple and reliable.
4.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.Lontg time short circuit of the load won't affect the PCB and batetry.Temperature protection during charging and discharging.
5.Extreme low power consumption.The consumption of the whole device is less than 50μA.
6.PCB use high anti-corrosion,high water resistance,high impedance ESD conformal coating.

How to Select BMS
1.Clarify battery type (LiNCM,LiFePO4,LTO),how many series in your pack,select the PCB according to number of series.
2.Clarify battery charging is common port or separate port.
Common port:charge wire and discharge wire share the same one;
Separate port:charge wire and discharge wire are separate.
3.Clarify which current you should choose:
Tips 1:The max current the motor need=Rated power of motor/battery pack voltage*2;
Tips 2:The current of the PCM must be higher than the max current shown on the controller.
4.Passive balancing via resistor to discharge higher cells,this works only if the batteries voltage difference is small.
5.Temperature protection:Can be  customized if you need.It will protect batteries via monitoring battery temperature.When it is under extreme situation such as exposing to the Sun.

Notice:
1. We can design it for various lithium batteries like LiFepo4, LiMn2O4, and Li-polymer etc.

2. The main functions are: over charge protection, over discharge protection, over
current protection, short-circuit protection, temperature protection etc.
3. According to the customer request we can develop PCM in different sizes and structures.
4. BMS manufactured by high quality Mos and IC imported . Keep your battery long cycle service life time.

Features:

1.Protection Circuit Board for 37V 10S 15A Li-ion and Li-polymer battery pack;
2.BMS applies for 10 cells Li-ion/Li-polymer battery pack;
3.To prevent the battery packs from overcharge,overdischarge,over current, over temperature ,short circuit ;
4.With cell balance/equilibrium function;
5.Compatible with both Li-ion and Li-Polymer cells.
6.How balancing function works? after battery pack is fully charged. PCM will detect each cell's voltage and trim higher voltage down until other cells reach the same voltage level. Therefore, it helps cells have longer service life.
