SEPLOS Mason Kit and x16 Grade A EVE LF280K Battery Bundle

Sold out

Please note: The V2 and V3 Seplos Mason kits are not compatible

Our Seplos Mason battery bundle contains everything you will need to create a DIY 48V 14.3kWh battery. As part of this bundle you’ll receive a SEPLOS Mason kit and 16 Grade A V3 LF280K EVE LiFePO4 cells with the SEPLOS Grade A Busbars.

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 so you must select the correct BMS type for your set-up. If this is your first and only kit, you can select the V3 BMS.

This is the ideal DIY kit for home energy and solar battery storage.

Seplos Mason Kits are modular in design and can be paralleled should you wish to create additional units.

The kit includes a 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).
