I like nimh better than lipos.
I ALWAYS have a habit to fully charge my NIMH packs when im storing them.
I try to cycle them once when i take them out of storage.
The maintenece doesnt bother me at all. Lipo's you have to do more maintence.
I have never seen a lipo fire either at the tracks i race at, only puffed lipos.
I'm just used to the "plug and play" aspect that NIMH has.
Lipo's have to be balanced, Nimh's do not.
There's just so many things you have to do to a lipo to keep it's performance to last. If one small thing goes wrong you can ruin the lipo.
Every once in a while I'll see someones ESC let out the magic smoke.
That's probably the reason why i have not smoked any of my esc's.
Personally Id rather play in the snow with a Nimh over a lipo.
I do it all the time, just let the battery dry for a few hours before i recharge it.
