Hi Colin - what's it going to power?

Hi Pete.I want one to charge li-po batteries,I have been told all kinds of batteries are suitable from car batteries,leisure batteries,to power packs but i dont want to recharge off my own car battery because i have been told by a car mechanic it can damage the alternator.

Not sure what to suggest really Colin - for the few times I've used a 12v field charger I've done it from my car cigarette lighter.
I haven't heard of alternator problems because of running a field charger from the car battery, and as yet I haven't heard of anyone flattening their car battery within the space of a normal flying session, through charging their li-po packs.

But suitable batteries can range from a motorcycle battery (15Ah or so) to a heavy duty leisure battery (100+Ah). Needless to say, the higher the Amp Hour rating of the battery the more li-po charges you'll get between having to recharge the battery

Hopefully someone with more field-charging experience might be able to offer a more useful reply
