how long does the battery last with using it constantly ?
in other words, will it last for a long day at carlisle without recharging ?
The first two years the batteries would last two full days. Then we had two years of zero use due to covid but I would still buzz it around the yard occasionally. Last year they lasted a full day of the Mopar show doing the whole swap meet as well as the show field. But at fall Carlisle they were dying by the time I hit the hill. But that's about the same as the whole Mopar show.
I asked a dealer about battery life and apparently age has something to do with how long they last. A full set will run me about $400 Canadian. If you figure mobility scooter rentals at Carlisle are $90/day, this isn't a bad price to pay to do at least three Carlisle events for a few years or more. There's zero maintenance other than the batteries and checking tire pressures.
Also, I built a fully detachable large rack that mounts on the front. I doubt it would hold an engine block without tipping forward but it will hold a lot of stuff. I generally leave it off and will go back to the truck and get it if I buy anything large enough to need it.
