4S EpicBMS 150A+ Lifepo4 Battery Management System for 12V DIY Batteries v2.0
05/13/2022 - Now stocking v2.0 BMS with large rear heatsink and single connection points for lugs.
Have the know how or guts to try your own battery build? Awesome! Do it with the best BMS possible. This BMS is for a 4S 12V configuration of lithium-iron-phosphate battery cells.
Due to overwhelming demand I am offering my BMS as a standalone product. If you have heard of the Overkill Solar BMS this is very similar. I liked that BMS so much but did not like that it was originally only designed for 100A so I decided to seek out the manufacturing company and have a higher spec unit built. The EpicBMS is nearly identical but slightly taller to accommodate 150A charge/discharge rate. All settings are fully programmable via the included Bluetooth module and iOS or Android app. There is also a Windows application and support for Arduino setups. It has low temperature cut-off by default set to -1c, high temperature cut-off, cell over-voltage protection, cell balancing
Includes BMS, balance leads, bluetooth module, crimp on connectors for balance leads
Hydraulic pre-crimped 4 gauge wire leads available as add-on by default with 1/4" hole lugs that fit 280AH style cells & 5/16 on charge/discharge side. Different combinations available by special request (1/4, 3/8, 5/16)
