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)
