Not at all. If the mechanical system is working properly (i.e. all the gears/shimming/setup/etc...) then power is power is power. As long as the battery you choose can supply enough Amps to power your system efficiently, at a voltage you desire...then you're good to go. Be it NiCd, NiMh, LiPo, LiFe/LFP, etc...
