1. Overview: 16s 200A bms is used for 16 series 52V battery pack. We can design it for various lithium batteries like LiFepo4, LiMn2O4, 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 service life time.

2. Advantage: Use top quality (A-level) protective integrated circuit IC, from the solution of Japan. Strong load ability, constant discharge current 25/35A/45A/60A, use high voltage resistance, low inner resistance 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
