[MorTech]

The charge/discharge parameters on the EZGO application are all WELL within the 80% capacity/1000 charge cycles. Most likely it will be closer to 90% after 1000 cycles. The charge voltage is 4.05V per cell with very low charge (0.15C) and discharge current. Even the momentary max discharge current won't make the cells breathe hard (perhaps 0.5C). I don't know the cutoff voltage in the EZGO application but I suspect it is around 3.1V cell or 43.4V total battery pack voltage. However, the regen braking parameters are an unknown so don't know how that will effect longevity.

Cell phones trade battery cycle life for charge speed to max capacity. They want you to upgrade every few years. I doubt you will even get 500 cycles in a cell phone. If you charge at 5W to 90% max then you will probably double your cycle life.

The bulk price is just the bulk price.
