Absolutely. I’ve only done it once or twice, just long enough to get the one low cell voltage high enough to switch back to lipo mode. Also, all the lipo charging I do is inside of a steel ammo can. My drone buddy teases me about it but I don’t care, big and/or lipo batteries are fucking scary.
If you try the ammo can idea make sure you poke a hole in it otherwise you run the risk of it becoming a bit of a pressure vessel.
