Seplos CANBUS/RS485 24V/48V 50A/100A/150A/200A Lifepo4/NCM BMS


You can find Seplos CANBUS/RS485 24V/48V 50A/100A/150A/200A Lifepo4/NCM BMS for prismatic or Cylindrical lithium battery pack from us.

Two kinds of BMS boards with different communication modes available: one is BMS using CANBUS communication protocol and the other is BMS using RS485 communication protocol, so that customers can have more flexible choices

Such BMS can support up to 16 units in parallel operation.


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:

 *The default is the Pylontech CANBUS protocol

 * Goodwe

 * Growatt (The default is SPF(off-grid) protocol. If your inverter is SPH(on-grid) , please contact the sales person)

 * Victron

 * LUX POWER

 * Sofar

 * DEYE

 * Sermatec

 * RENAC

 * TBB POWER

 * SOLIS

 * SMA

 * FoxESS

 * IMEON

If the inverter brand is not listed, please ask your inverter supplier for the protocol to define. We'll help confirm that.
