How to build your own LiFePO4 battery
A DIY battery needs cells, a BMS board, busbars or nickel strip and a case. Here you will find EVE LF280K (3.2 V, 280 Ah) and LF105 (3.2 V, 105 Ah) prismatic LiFePO4 cells, JK and Daly BMS boards, copper busbars and nickel strip.
How many cells you need
The number of cells in series (S) sets the voltage: 4S gives 12.8 V, 8S 25.6 V and 16S 51.2 V for a 48 V inverter. Parallel groups (P) add capacity. For example, 16 EVE 280Ah cells in 16S give 51.2 V and about 14.3 kWh. We walk through the wiring and BMS step by step in How to build a 48 V DIY battery, and the DIY configurator works out a parts list in a minute.
Choosing a BMS board
The BMS protects cells from overcharge, deep discharge and overheating and keeps them balanced. Its S count must match the battery and its current rating should exceed the inverter current with headroom: 100 A or more for a 5 kW, 48 V inverter, 200 A for 8 kW. JK boards with an active balancer suit large packs; the Daly 4S is made for 12 V batteries.

FAQ
How many EVE 280Ah cells do I need for 48 V?
16 cells in series (16S): 16 × 3.2 V = 51.2 V. That battery stores about 14.3 kWh (51.2 V × 280 Ah).
Which BMS should I use with an inverter?
The same S count as the battery (16S for 48 V) and a continuous current 20–30% above the inverter’s maximum: 100 A or more for 5 kW, 200 A for 8 kW.
What is the difference between LF280K and LF105?
The LF280K holds 280 Ah and suits large stationary 48 V batteries. The LF105 holds 105 Ah and is lighter and smaller, so it is used for 12–24 V packs, boats and campers.
