I am lookinng at buying a new pede and i am not sure which model to get. The price isn't the issue but i am leery of the potential risks associated with the lipo's. I would like to use the 2s batteries but i'd also like to use the nimh packs i already have, Is there any risk with running nimh with the vxl? Would using nimh shorten the lifespan of the esc? Thanks for the help!
