SEPLOS Mason 48V 280Ah DIY Battery Kit (14.3Kwh)

SEPLOS Mason 48V 280Ah DIY Battery Kit (14.3Kwh)

Seplos
£499.99

Please note: The V2 and V3 BMS are not compatible.

The Seplos Mason Kit includes all of the critical components required to create a DIY 48V 14.3kWh battery (prismatic cells sold separately).

We offer both Grade A and Grade B kits to account for the different terminals found on our EVE LF280K Prismatic Cells (Grade A & Grade B). The overall size of the kit does not change, however, the supplied busbars are different depending on your choice of prismatic cell.

There are two different types of BMS, the V2 (pre-December 2023) and V3 (post-December 2023). It's important to note; the V2 and V3 BMS are not compatible. Not sure what kit you have? Get in touch with our team and we'll be happy to help.

This kit is also suitable for EVE LF304K cells, to create a 15.5Kwh battery. LiFePO4 Prismatic cells are available to purchase here (16 required). We also offer a vertical, mountable version of the Seplos Mason kit - which you can find here.

Seplos Mason Kits are modular in design, and can be paralleled and stacked should you wish to make additional units, thus increasing your overall capacity in the future.

 
The kit includes the Seplos BMS (complete with Bluetooth) - which can be used to communicate with several inverters via CAN & RS485 such as Victron, Growatt, Sofar, Solis and more (a full list of inverter protocols can be found here).
