I am chargeing up to 6s 2P 5000mah at 20 amps this way.
Yes!. Buy a deep cycle marine, keep in drunk. Charge that from the car when needed. Now you got a double buffer. Plus you can jump yourself when needed always having a fresh 12v in the trunk.
Also, you don't have time to be charging bats at the field. +-1hr per pack at recommended 1C rating, you will be waiting all day. Buy more Lipo packs for the planes. Done.
