CALB 3.2V 68Ah - LiFePO4 / LFP / Lithium Iron Phosphate Prismatic Cell
217Wh Lithium cell - 5 year warranty, 3000 cycles @ 100%
Why 68Ah?
As lithium cells become larger, their cycle life decreases, 68Ah is a good balance between practicality and lifespan.

5-YEARS after-sales guarantee.
After 5 Years OR 3000 cycles, whichever is first:
- the cell capacity must meet or exceed 54Ah
Providing:
- A BMS with cell balancing and overvoltage/undervoltage logging is required to prove suitable usage of the cells. Please see the Daly BMS or REC BMS units.
- The battery is being charged with lithium compatible chargers
- There have been no out of tolerance events
- The battery is stored out of the elements (under-bonnet use not acceptable)
