it says there using 10 130ah 12V bats.
and there saying it can "in theory" take 2,300LBs 20 miles at 20 mph, not bad.....would like to know how long it runs a tiller or a mower....that would be more realistic to hours of usable run time.
trouble is 2,300LBs is WAY LESS than what im talking about
like over 7,500lbs less....that does not include any working load eather.
also im not talking about driveing around in a parking lot, we have some grades that push\go over the 20% mark and many in the 7 to 15% range.....
granted most of the pulling is down hill.
using bat of that size, i think i could jam 30+\- of them in there...
a plug in, diesel-electric is looking more and more practical.
