thanks. yeah i figured id just messure before i bought any others. but can you help me with the 40c burst i mentioned before? ive been looking at some nice batteries that say 30c constant and 40c burst (10 seconds). just wanna know if that burst will damage anything or if its fine since its just a burst. i was told to not go over 30c with the backdraft 8e. i would love a constant 25c or 30c and burst of 40-50c if its safe. ive seen some 30c constant and 50c burst so if its safe id probably go that route. thanks for the info on the battery size. im sure if its a little small i can find a way to make it not rattle or move.
