Customer can not program the board, we will preset the board according to your battery's specification. Communication via EV2400 or EV2300
What we need to know from customer? |
1. Cell's manufacturer and module number
2. How many in series and parallel
3. What is the capacity of battery pack
4. Maximum continuous discharge current
5. Maximum surge discharge current
6. SMBus or RS485 or RS232 |
For other PCM/PCB, please check our PCM/PCB/BMS/CMB/UPS category
Warning
- If you want to use this protection circuit board for a battery that is less than the rated drain, you must add additional protection device to protect the battery itself. Such as: proper rated polyswitch.
- You must be professional in Lithium battery pack to buy the protection circuit board. Misusing may cause battery damage or explode. We are not responsible for any damage caused by user.
