Re: PAS backwards - how to flip?

I flipped two of the wires, ill try to find the one I did to see wich wires I flipped. theres a signal. example, 010101 but if on wrong side you get 101010. I flipped 2 wires to make it 010101 again

Re: Runabout Upgrade - 20" wide tires Mule with DD hub motor

I saw you had drilled 3 holes in the square tubing where you have thick wire running, I thought the other two were getting rodded through the case, holding the weight off the bms but I didn't see any nuts on the outside of the case. I was just curious the bms does have those stand off things. nice b...

Re: Blown halls

ive never used those testers but youd think atleast some kind of lights would go on, maybe its the red or black hall wire that's broken

Re: Blown halls

I would be tempted to check for continuity of the hall wires. ive never blown a hall sensor, its always been the motor cable where it passes through the axle gets damaged.if you don't have a dmm maybe try hooking the ebike tester back up and wiggle the cable at the axle and see if the lights give a ...

Re: Top 3 (18650 cells) for high continous Amp output?

did you mean the bms is 100 amps? if so you can split the pack and parallel the two 5p packs together using two bms gives 200 amps. if your thinking 25r you might consider the 30q at 12p No I cant split it. Yes em3ev said the BMS can handle 100A. But if the cells can handle 200A, then how could I g...

I wish I could fit a 3.0, I think im a 2.20 on the back tire.

Re: Adding cells to a pack

id check to see if your bike will turn on at 68v, I wouldn't up the amps on your bms, if your running 21700 with 5000 mah, its probably called a 10 amp cell but really you need to find out what 21700 it is, like a Samsung 50e is a 10amp cell at 5p is 50amp bms if you pull more than 50amps from the p...

Re: fast charging through phaserunner

it gets really interesting if youre running 48v or 52v or 60v or 72v solar panel to the equation.

I saw doctor bass was asking about solar charging at 48v and I thought about nucular needing 53v then boosting it for charging.

the pf lifecycled at 4amp discharge has 2500mah after 300 cycles on the spec sheet, sounds good to me. that boats going to float like a cork bobber. are you going to have to some sort of gear like a 2to1 or just play with different props

Re: Speed limit 25km

yes but if you had something like a wireless key fob that turned on and off the switch inside the controller the cops would have a lot of fun trying to figure it out. unless they get your fob that throttle isn't working. this was fun.

Re: Speed limit 25km

is it against the law to have a street legal/off road switch. street legal is pas only. all it does is turn off the throttle. off road turns on throttle.

Re: Electric 22 feet speedboat from 1957

I think youre asking for too many amps from an 18650pf. 550amps from 60p is about 9amps/cell. and that wouldn't be a quick burst. from the boat sitting still how long would it take to get on plane? im no expert but it would really suck to spend all that money on batteries and time doing spotwelds th...
