@LeoTheHuman,
Do you have a spare 12v vehicle battery laying around? Even though this might be considered irresponsible (I have no idea) I’d just hook up a 12v charger (turnigy accucell or something) to the battery with the alligator clips it comes with. That’s how I charge all the time, but sadly I haven’t gone on any trips with that setup.
Another option is if you can get a 12v plug (the kind in a car) that has contacts on the end, then you could use your car’s 12v system to power the charger, etc.
As for the 12v battery I know you can get contained ones specifically for this kind of thing. It’s nice to charge off a big separate battery, as you have a reliable power source that won’t be interrupted.
You know there’s reasons to be cautious with LiPos, but you’d probably be fine charging in the car, there’s just the risk if the LiPo does burn up you’d have to pull off, etc. which could pose to be a problem. As that (hopefully) won’t happen, I don’t see why not go ahead.
I actually don’t have any experience on the subject so this is what I would do, but someone else might have actual experience, so I’ll be watching this thread.
