We should be moving towards Li-ion for RC tanks, since weight and speed are not a factors at all.

I don't see the issue with sticking with a 5000mah nimh battery pack either. It pretty much lasts an hour for a 5kg tank at max volume with lights, which is more than anyone needs. If you go longer, then get 2 packs and charge one with a fast charger will using the other. Certainly cheaper than using lipos with a good charger, LVCs, and all the other tools you need to make it run safely.

All batteries will burn, but lipos are by far, the most temperamental and destructive.Can't take hard knocks, needs constant supervision while charging, need LVCs, charging bags (doesn't work - see youtube), and other nonsense.

Charging bags don't work either. The only way to reasonably store them is in an ammo box, lid off with a bad of sand on top, and even then, there's still smoke damage. Every other way is just asking for a fire.


Burning down a $1k tank aside, property damage is far more concerning. I'm a homeowner, and no lipos will ever be passing through my doors.
