18650 4S 12V 15A 20A 30A 40A 50A 60A Waterproof BMS For Rechargeable Lifepo4 Battery With

Same Port for lithium battery

BMS, short for BATTERY MANAGEMENT SYSTEM, is the link between the BATTERY and the user. Its main object is a secondary battery, mainly to improve the battery utilization rate, to prevent excessive battery charging and excessive discharge, which can be used in electric cars, battery cars, robots, unmanned aerial vehicles.

4S 8S 12S 16S 12V 24V 36V 48V BMS For Lithium Battery

◆EVL4S12V 15A/20A/30A/40A/50A/60A PCB is used for 4 series 12V lifepo4 battery pack. ◆We can design it for various lithium batteries like LiFepo4, LiMn2O4, lipo and Li-polymer etc. ◆The main functions are: over charge protection, over discharge protection, over current protection, short-circuit protection, temperature protection etc. ◆According to the customer request we can develop PCM in different sizes and structures. ◆BMS manufactured by high quality Mos and IC imported . Keep your battery long cycle serivce life time.
