48v carts draw around 50-70amps on the regular to power the 3hp motor but require more for initial movement, going up hill or continuous wide open throttle. First tests with just the single unit allowed me to run it around at a moderate accerleration and speed and even went WOT for a brief stretch without tripping the BMS. I did not try any lengthy hill pulls because if it does trip, I need to push it back up the hill and to the house to hook to the charger to reset. I havent built by step up yet to reset. I will test that once I get my second pack in. In the brief time of driving the cart I have been pleasantly surprised by the pack. The pack is rated at 50A continuous with 200A peak for 10 seconds.
