You don't have to put it in tow or disconnect the batterlies as long as you are careful when checking each battery.

Re: 48v load test batteries
The easiest load tester IMO is your cart itself. Drive it full pedal up the biggest hill you can find. :)

If you have an Alltrax controller SR or XCT you can connect a laptop and collect a monitor file while running these tests. The resulting file will show how much amperage the motor draws and the voltage sags at any given moment. |

Re: 48v load test batteries
Thanks guys, to be honest I tried using the cart itself under load. Im in Florida and not really any hills here. I couldn't tell a **** thing trying this LOL. I have changed the battery meter to a SOC volt meter. Voltage drops down to 47 at full throttle.

Re: 48v load test batteries
Assuming you are running Lead Acid, that's not concerning to drop to that level.

Re: 48v load test batteries
If you want to see max Amp draw, this has worked well for me.
