Works great.
Charges 10S6P 18AH pack at rate of 2.5amps in full sun.
I use it for both my Etrikes.
Anchored 100W panel to south-facing side of garage.
Grounded panel to steel pipe on gas meter using 12awg solid copper.
Drilled 1/2" hole through wall for 12awg solid copper wire to charge controller.
Inside garage (other side of wall where panel is anchored) I mounted shelf for electronics.
Charge cable is 10' soft multistrand 12awg appliance cable.
I'm using a programmable (set to 41.5V) boost MPPT lithium 12V solar charge controller.
Also using "positive disconnect" Lithium Battery Charge Controller Protection Board set to 42V.
BMS overcharge disconnect protection on BMS as well.
