I used a agm 12 volt 18 ah agm battery lasted about 45 min but had very low power to push dirt it was fine to push snow but that's about it .what I found is that when I test the voltage at each motor with a sabertooth 2x25 I was only getting 6.7 volts to a motor . I would recommend to find some large higher voltage lipos turned my dozer from being a turd in the dirt to having all the power I need plus it last twice as long with out such a drop in power as the battery gets low.
