hi all, i have a question.would a 12 volt motorcycle battery be ok to use on a ac/dc lipo charger.as my car battery is sealed in a plastic box and a pain to undo and connect wires to.

If your charger has a 12V input
you will be fine although you may not get many charges

Depends on the Ah rating of the motorcycle battery

I think most modern motorcycle batts tend to be small but powerfull gell cell type batts, not sure how they would cope with a couple of "deep discharges" if you have a good few flights & charges on the same day.
I say this because a couple of years ago I eneded up flattening a 40AH batt after a good day at the field & ended up having to jump-start, had to replace it a couple of months later as it was well "donald ducked"(was a couple of years old though to begin with though)

yes it is a gel type.will find out next year when im at field all day.i do no my charger has a warning to tell you your car batt is below a certain voltage.so you don't get stranded.so on this info i can then run it till the warning sounds then determine.how many chargers i get .if i only get a few then will have to have a rethink.
