Hey! AEPs are great and I won't stand idle while they're slandered!
There are two ways I've got to charge my AEP batteries (I have the TM MP7 AEP and it's a lovely little gat, especially for people who think "he's a sniper, just rush as he won't have full auto!"). First way is that I have is using the
TM AEP battery adapter thingy that the MP7 uses an combine it with a
adapter to plug it into my smart charger. Second way I have is a custom job that I got from a friend who knows a guy who knows how to do wires that basically I plug the balance lead into and it has a balance lead and deans connector out, again so I can plug it into my smart charger.
If you're using NiMH batteries you don't have to worry about it. Just plug them in for a while and they'll be fine. My lipos generally take about 40 mins from storage voltage (whatever that is)
