DL21S 72V 20A PCB is used for 21 series 72V battery pack.
The main functions are: over charge protection, over discharge protection, over current protection, short-circuit protection, temperature protection etc.
BMS manufactured by high quality Mos and IC imported . Keep your battery long cycle service life time.
Uses top quality (A-level) protective integrated circuit IC, from the solution of Seiko of Japan.
Strong load ability, constant discharge current 20A, 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.
Extremely 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.
