1. Overview

DG6S45A PCB is used for 6 series 24V 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.


2. Advantage

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


◆Strong load ability, constant discharge current 45A, 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
