Details

Charging at 1C means a current equal to the pack’s capacity: divide the mAh by 1000 and you have the amps. A 1300 mAh pack at 1C is 1.3 A. The card has the sums done for the common FPV pack sizes.

1C is the cautious default. Some packs allow faster charging: check the label before you set more. On a parallel board, add up the capacity of all the packs, and only connect packs with the same cell count.

A black and white table with the default line in red. Stick it on your charger, your LiPo bag or the charging station.
