5kwh is about the usable rating of the original lead batteries. Plenty of power to run either the cart or my 48V UPSverter.

Would it be possible to fit current limiting cct so you drop the surge volts when going up hill - better to turn the wick down rather than keep tripping the bms on OCP - 500A @48v is a lot of dc spark energy to break for solenoid kit. The PWM speed control box on board can probably be repurposed to reduce speed on overload. Attention to motor starting inrush needed - probably a feature of the cart control box - or does it start with a big kick?
I would advise you treat a Lifepo conversion with tender care as the FLA was a crude animal by comparison
I would advise you put a rubber foam mat under the rack to help absorb riding shocks.
Is you battery box fuse protected? Do you carry on board some proper cable cutters if it goes nuclear. FLA history makes you careless.
Done properly, a Lithium conversion is a huge improvement - but the devil is in the detail.
BTW, how do you recover a GC when it breaks down? Not as if you can push it? Tow it? Trailer it

Would it be possible to fit current limiting cct so you drop the surge volts when going up hill: My foot makes an effective current limiter. I purposefully tripped once to learn, and only tripped once on accident. South TX is flat so hills are not a problem. Worse case I purchase a second SOK for 10KWh and 200A
The PWM speed control box on board can probably be repurposed to reduce speed on overload. The motor is AC so is inverter controlled. I know of no method to limit the current.
I would advise you put a rubber foam mat under the rack to help absorb riding shocks: Per above the ride quality greatly improved with the ~300lb weight reduction. Minimal road shock and I never go offroad.
Is you battery box fuse protected? SOK has a front mount circuit breaker that I can easily access to shutoff.
BTW, how do you recover a GC when it breaks down? There is a “tow switch” that prevents regen breaking. Towed it a couple times when the terminals corroded [worst thing about FLA]. Rolls very easily without power.

Good to know buddy. Yes your right foot is your current limiter! So here's a thought make up a force feedback like a servo motor driven spring that pushes back on the gas pedal. So the more current drawn, the more force pushing back to tell you to ease off on the pedal - a simple low cost expedient, or how about an Amp meter on the dash board (hall effect type) so you know when you are redlining - that would be an easy fix - or maybe get a sounder that starts up wailing or something when you are in over current region, could make it an Alexa sweetie "Hey Barnie you are making me hot"
Lifepos need a proper bms like JK with BT readout and cell balancing. Flying blind is not wise
