Let's look your old throttle's wiring diagram Red- is battery power. Black - ground for both the LED panal and the Hall device Green -...

That's a KT display that I never heard of, the LCD800. Can't find it in Google. This is just a recap from your document. P2 = magnets x...

Maybe the power wires behind the XT60 have frayed down to a few strands? That could drop 10-20 volts.

The battery is a lie. With the best cells in the world, a 7s3p arrangement will be 10.5Ah. This battery is probably 6-7 AH if you're...

P1 is (the number of magnets) x (gear ratio). Your count includes the gears turning the motor. If you're getting the right speed, then...

I think the big clue is the drop to 30V. A 52V or 48V battery with a BMS cannot show 30V on the output. If you see that, it's just...

I wouldn't call them slick but we all have different standards The Marathon tires can get pretty aggressive but are specialized in...

Motors should have different windings when offered with 20" rims versus 29* rims, You want the higher speed windings for same wheel...

Start with a full charged battery. Put it under load and monitor the Ah or WH or whatever your "coulumb counter" measures along with the...

Almost certainly either your throttle ground is broken, or you have something else (PAS, etc) connected to the throttle signal wire that...

Former Ecotric owner. I've read on the ecotric facebook forum that S900's from different models are not compatible. . I'm sorry that...

Screwdrivers will scratch the rim and puncture tubes, unless they are really old with wide dull blades that are rounded off.. I use...

The shiny plate on these adapters is like ,10 inch steel. Too thin to work as a torque plate. If they are braced against the dropout, a...

I did not realize you had already measured all the groups. Normal operating voltage of a lithium cell is 3.0V to 4.2V, The typical BMS...
