4.2ah OnlyAmps "Pint BIGBOI" 21700 Drop In Pint Upgrade

Compatible with hardware 5314 / firmware 5050 and earlier. Newer hardware / firmware will attempt to end your ride after energy equivalent to the stock pack has been expended by initiating low battery pushback and various errors. Rewheeling/downgrading firmware to an earlier version or using an OWIE chip to get full range may be possible, though with each new hardware and firmware revision these tactics become more difficult. Pints with internals replaced with VESC can access full range without issue.

I want all my customers to be satisfied but the Ebay return policy can easily be abused by the buyer (buying pack and improperly installing, using faulty equipment or "renting" a battery). My reviews are great and I would not jeopardize them by not honoring my reputation and my word.
