Our advantage
In stock , Welcome Dropshipping, 3 years warranty ,Free replacement for any quality problem .


◆separate port for charge/discharge We can customize any PCB from 1S to 30S lithium batteries with different current.

◆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

◆Use top quality (A-level) protective integrated circuit IC, from the solution of Seiko of Japan.

◆Strong load ability, constant discharge current 10A/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.
◆PCB use high anti-corrosion, high water resistance, high impedance ESD conformal Coating.
