Default Things I’ve done so far.

2021 I60L with dealer installled twin 56Ah roypow packs in parallel with the roypow green lithium charger. Originally was going with the single 105Ah but the hills around here with the lifted 6 seater was causing the BMS to shut down the battery. Putting two in parallel gives the same capacity but cuts the amperage to each BMS in half. We have gone up and down monster hills with no issues.

The dealer could not figure out how to remove the onboard Icon (Delta Q) charger so he left it and wire a separate power cable for the new onboard charger.

I removed the factory charger and routed the new charge input to the factory port so that functions like normal with the removable power cord. I had to go back to the dealer to pick up the cord because they didn’t include it. The SOC is a little iffy because I dont think it is set up for lithium so i installed the Roypow supplied power meter in the dash.

The trick to removing the factory charger is a two wire cable from the charger that supplies on/off logic to the motor controller so that you can’t drive off with the charge plugged in. A jumper across that connector fools the controller into thinking that the charger is disconnected and the cart will run, i just have to make sure to not drive off with it plugged in. This can also be done in programming by disabling charger check (Line 5) in the programming.

I’m going to try to trade my factory charger back with the dealer for a spare roypow charger or sell it to someone who needs a spare.

I installed the 2” aluminum spacers from amazon, definite improvement in stability.

Dealer upped RPM to 5000 to give 25 up from factory 19 mph. I make take it 30 but 25 is plenty fast for my wife.

I installed a backup camera powered by the power cable that originally went to the very annoying backup horn and it comes on automatically when switched to reverse. Very very nice unit for 35 bucks.

Installed the flashing turn signal side mirrors. Dealer installed bluetooth stereo with speakers in rear deck behind second row.

I built the cable that Atrain suggested and it works like a champ. We probably get 25 miles of more before the charge gets below 50%. The lithium maintains full 51 volts throughout the discharge range which is great.

I rewired everything the dealer did and put the wires inside plastic wire loom to protect from elements and routed everything neatly up high on the chassis to prevent any damage.

Some pics attached. Hoping Icon will come out with some glove box covers soon.

This forum is great and I love all the great ideas and experiences. So far I am thrilled with this cart.
