I have 32 Vapextech 4300mah nimh cells that need a home- only used a dozen times if that, just need reassembling with decent battery bars. I'd rather give them away for free (just pay shipping) than let them rot away sat on my bedroom shelf; sure someone could make use of them...
Lipos would be better for sure though, they arent that expensive, easy enough to charge and look after, and the power & runtimes are just brilliant compared to nimhs, not to mention the weight savings. No pressure....
