Q: Which 50ah or 50ah pro would be ok for a golf cart? is the 50ah base version have much worse cells than the 50 pro? whats the 50ah pro advantage? thx
A:"Dear Customer, Thank you so much for reaching out. I'm so sorry to tell you that Timeusb batteries are not supposed to apply on Golf carts because the current required when the golf cart is turning corners or going uphills might be much higher than the BMS's Max. instant discharge current. If the current is too high, the batteries might be shut down for protection. So it is kind of dangerous if the golf cart stops when you're going up a slope or a hill. For your safety and a better battery experience, we suggest you going for specified golf cart batteries If you need anything else with other battery application, we'll be glad to help you figure out. Hope you have a good day. From Timeusb Service Team "
