Model: DG20S100A( 3.7V Rated Li-ion Battery not for 3.2V rated LiFePO4)

 

Constant discharge current: 100A 

Peak discharge current: 200A 

Charge wire and discharge wire share the same one.

We can customize any PCB from 1S to 30S lithium batteries with different current.

 

1. Overview

DG20S PCB is used for 20 series 72V 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 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

 

3.Technical parameter

(The following is an example for 3.7V rated  battery.

If your battery is 3.2V rated LiFePO4, we will set the parameters for it )
