20S 72V 100A Li-ion 18650 Battery Pack BMS/PCM/PCB for Electronic Devices
Model: DL20S (3.7V rated Li-ION Battery not for 3.2V Rated LiFePO4)
Common Version : common port for charge/discharge1. Overview
DL20S72V80A/100A PCB is used for 20 series 72V battery pack.
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.
2. Advantages
Uses top quality (A-level) protective integrated circuit IC, from the solution of Seiko of Japan.
Strong load ability, constant discharge current 80A/100A, 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.
