Howdy all,

Purchased a one owner 2017 RXV last march, and have been working out the kinks. It came with a set of 215/35r14 backlash tires, no lift, and the 235 amp curtis controller was programed to 23 mph by the original dealer. It has a 48v "4-12v trojan 1275" setup. The batteries have had to be replaced, 3 in 2019, 1 in 2018. After sifting through BGW threads for a year come to find its not the most reliable setup even with good maintenance. AKA stunted range after extended storage, low total amperage available to the drive system. So, I did order a lester summit II to see if I can extend the battery life/range for a few more seasons. Also, after fighting micro leaks in the back two tires all summer I ordered four Duro 225/40r14... 21" tires , and for better fitment for the cart.

This is where I think I'm making the mistake. I've come across a few posts from a well experienced expert... Mr. Boyce, where by going bigger than 20.5" the stress on the drive system is too high, and will burn up the 235 amp controller. But, this is the only place I've seen or heard of this. Is this running at max speed, at max potential/full controller amperage for extended periods of time? Or just running the cart? This cart is primarily used on the golf course, but I do get up to max speed running the dogs, but they can only run so long before they need a lift. I haven't come across any threads with detrimental issues or horror stories, but any incite or shared experience would be greatly appreciated before I fix a headache with a hammer.
