Somehat off topic... What voltage do those buggers operate at? I always
wondered if a trickle charger, the kind I use on my car or motorcycle
could even keep up if the voltage was compatible.

Mine's 12 volt, 36 volt is very common too. It pulls 50+ amps charging. I
tried a farm heavy duty charger at first many years ago, didn't have enough
power.

Mine is 24V, and the battery is 1,571# and 875AH. I charge mine with a
little 10A charger and it will take several days to top up.
