4S 60A PCM/PCB/BMS Protection Circuit Board for LiFePO4 LiNCM LMO

Rating
$24.78 $22.30





Model: DG4S60A

Constant discharge current: 60A

Constant charge current: 60A

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

DG4S50A PCB is used for 16series 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 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.

◆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

4.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 )

P-: Connect to load -

CN1: Voltage detection terminal for each cell

C-: Battery charging –

B+: Battery charging + output

6. Operation instructions

6.1: Battery connection sequence: First connect B-,and then connect other cell voltage detection terminals.

6.2:Cell volt detection terminal use 2.0 distance wires loop, the 1 st pin of CN1 is B-, the 2 nd is B1,the 3 rd is B2…… 17 th is B+

6.3:Cell voltage detection wires use standard wires ,B- P- need to be appropriate wires in terms of constant discharge and charge current.

6.4:After the wiring is finished, please measure the voltage between B+ and P-.

If the voltage is equal to the total volt of the pack, it means the PCB is working fine.

Attention: Connect the PCB to battery cells, or disconnect from the pack, you must follow the instructions above. If you don’t follow, it will damage the part of PCB and result in serious result.
