All about making LFP Batteries

 as per rates in jun 2026 

1) LFP cylindrical cells for small projects cost Rs.5 per watt 

 suitable for small projects.. lessthan 100ah - 3.2 volts

if your projet needs 12volts and 100ah then using Prismatic Cells are cheaper ---  (max is 3.2 volts indvidual cells- join 4 cells for 12 volts join with bolts) - life 2 to 3 times high uo to 6000 cycles vs 2000 cycles for cylindrical --

Prismatic cells are avialble even in 50ah but cost difference between 50ah and 100ah is much.. beyond 100 ah difference is less.. 

minimum cost for 12 volts set comes to 9500 for 4 cells and case and BMS

Ganfeng 100ah Lithium rechargeable phosphate cell - 3.2v 100AH - 320WH - 1900/- 5.9 per watt
