no with gp 950s or most batteries for that matter you should get at least double that. one of my mini-z mr01s has the spider turbo with gp 950s and i have no probs. honestly you should recheck your charging specs with your batteries and make sure you charger is for nimh and you are letting it charge for the right time corresponding to your chargers mah output and the mah on your battery (950mah)…..oh yeah and it is possible…very possible that you got a bad set of gp 950s thats been d.o.a or sitting for too long.
