1. We can provide seplos CANBUS/RS485 24V/48V 50A/100A/150A/200A Lifepo4/NCM BMS,for prismatic or Cylindrical lithium battery pack
2.We can provide two kinds of BMS boards with different communication modes, one is BMS using CANBUS communication protocol and the other is BMS using RS485 communication protocol, so that customers can have more flexible choices.
3.Our BMS can support up to 16 units in parallel operation.
4.The main functions are: CANBUS communication,RS485 communication,Passive balance,Individual cell over voltage. protection,Over (under)voltage protection,temperature protect,over charge(discharge) protection, over current protection, Short circuit protection etc.

Attention: when we want to view the battery pack parameters through the battery parameter monitoring software, we need to use the Rj45 to USB Adapter to connect the battery pack to the computer. We recommend that you purchase an Rj45 to USB Adapter from us.Adapters purchased from the market may not work properly due to the definition of the hardware.

CANBUS mother board

Now our CANBUS communication board supports these brands of inverters,and our BMS has built-in CANBUS protocol of matching inverter brand, which can be automatically matched or manually switched:

 

RS485 mother board

Now our RS485 communication board supports these brands of inverters,The BMS with RS485 communication has a built-in RS485 protocol, please confirm with the salesman before buying what you need is that one RS485 protocol.

Seplos history

Q:Does your BMS have current balance?
A:yes,We have the current passive balance function, the passive balance function module is integrated on the BMS board, do not need external balance device.
