Prismatic 3.2V LiFePO4 cell with red and black terminals

LFP cells

LiFePO4 cells in cylindrical and prismatic formats

Same iron-phosphate chemistry, two shapes. Cylindrical parts span IFR18500 (850mAh) to IFR42110 (10Ah) and suit packs that must fill awkward spaces or deliver high current from a small footprint. Prismatic parts span 10Ah to 300Ah in aluminium or plastic housings and suit storage banks where space efficiency counts.

Size a bank before you sample

For every cell we list the dimensions, the cycle life measured at 80% depth of discharge, the maximum charge voltage and the weight — enough to lay out a bank on paper first.

Bought by

Pack builders who assemble their own modules
Storage integrators ordering prismatic cells by the pallet
Lighting and instrument makers needing one exact cylindrical size

Solves

Data sheets that bury the test condition behind the cycle figure
Mixed batches that refuse to balance in series
Enclosures no published cell seems to fit
