2005 G22e Lithium CloudEnergy

Ok, this isn't my cart, or my battery choice. My neighbor got this cart for his dad cheap, the old lead acids were boiled dry. He bought this battery off Amazon, dropped it in, then couldn't get the cart to drive. I had never worked on a Yamaha before, or a FSIP controller (51-FX302G027), or the weird voltage reducer (It's 16.8-13.6 step-down, can't find it on the internet but Sure Power 2112). I have encountered the motor before (AM&D DG1-4033). I offered to help because I was tired of staring at spreadsheets that day...

Some previous owner really hacked the wiring on this. Mismatched colors, vampire taps, ignition switch bypassed...
Once I figured out the ignition issue I could reset the controller with the tow/run switch key switch dance. That allowed it to start driving, and after a little jerking it seemed to learn and drove smoothly. That's as far as I've gotten. Owner is a handy dude who is good at 12V wiring so he may just finish it and rewire the whole thing.

The battery is super easy install. I would have gone with busbars, but the studs are deep enough for the charger and 12V step down to also fit. The BMS is a standard Xiaoxiang smart unit, but I don't hear a contactor inside when switching the battery on and off so I wouldn't use this on a lifted or high-powered cart, or in a steep hilly area. I also don't see any battery heater in here, so don't charge it below freezing!

Overall for the price, it's pretty good quality. The included charger is standard amazon variety, but has good heatfins and a fan, and uses Anderson connectors.

Were it my cart, I would most likely put a base in the battery compartment, upsize my motor wires, and reroute wiring and components to have an underseat storage area, as well as redo the 12V wiring.
