Product Description :

Deligreen BMS 4S 12V 80A 100A 120A 200A PCB BMS for 3.2V LiFePO4 battery pack 18650 Lithium Battery Pack

Model: DG4S BMS( 3.2V rated LiFePO4 not for 3.7V Rated Li-ion Battery)

Constant discharge current: 80A 100A 120A 200A 

Peak discharge current: 100A 200A 300A 300A 400A

Charge wire and discharge wire can be common or separate. Please choose what you need.

We can customize any PCB from 2S to 24S lithium batteries with different current.

1. Overview

DG4S BMS is used for 4 series 12V 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 200A, 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 3.2V rated LiFePo4 battery.

If your battery is 3.7V rated battery, we will set the parameters for it )
