Aloha, All. I have the hksunwin 800w 60v controller and it just died on me. It was 8 months old and had around 2500 miles on it. Is this a typical life span? Here are the conditions it worked under. I cruise at 800-1500w and up to 2500 sometimes @ 64v. then why is this controller...

Aloha, All. ok this is really weird. I accidently "over-charged" my 5000mah LIpo 4x4s=16s hardcase turnagy cells to 72v (4.5v per cell) last nite. They didn't get warm and there was a LOT of AH in the 4.5v and down. (ie the battery did not deplete quickly at all in the 4.25-4.50v range...

Aloha all. for my CA...is there a way to: 1) change the display to show amps rather than amp-hr remaining? 2) slow the watt display so it is readable? Now it is a blur as the wattage changes too fast. thanks Francis

Aloha, I mentioned before I am getting jerky starts and suspect the Halls. Here are the tips from Leaf to trouble-shout and what the results: Connect all wires,power on.Just disconnect that white big plug with five wires( yellow,blue,green,red,black) Then measure controller’s hall sensor: *...

It says it is for 6/12 v. How will it drain a 3.4v battery? Will it take forever? I have the smaller/plain load tester that you hold the switch on and it heats the element inside, is this the same as the Carbon Pile Load Tester?

Aloha, I have a bank of 400ah "Thundersky" 3.5v batteries and one of them is a bit high. All the others are at 3.35v and this one is at 3.5v already. How do I knock it down? I read all about toasters and heating elements here but they assume 36v or so, but mine is only 3.5. What can I...

Aloha, I just bought this hub and working a bit on the frame for the wheelchair trike. (similar style to the gas 'ped below.) QS V3 Hub Motor 4000w-6000w 1500rpm Electric bike, Scooter, Motorcycle 4kw-6kw This is what my gas moped trike looks like that I will now make another the same style...

If you are fully convinced the amps\volts controller are correct, in spite of the suggestion above. And Not able to limit your wrist action to 1/2 twist on the throttle Then you will need to: Get a Cycle Analyst to program your wattage or fashion a stopper or some block on your throttle to...

I am running my motor at up to 900RPM. Would that mean that the halls are working properly? (ie 38mph, 14.3" dia tire) francis

So is the only function of the halls are for smooth starts? francis

Aloha, When starting out, the motor hesitates and goes into reverse for a split second and then forward causing a clunk. (If I slightly roll forward it is fine. I checked all my wiring and also did a "re-learn" but still happens. Probably totally unrelated, the motor is totally silent...

I solved the squealing by putting a bit of teflon tape behind the pad instead of grease. lets see how long that lasts. francis

Aloha All, I have built my "bicycle" setup and now want a bigger road worthy motorcycle, so to cut to the chase ------------------ Here are my parameters For a motorcycle/Scooter (125-150cc frame) which motor and controller would I use to do the following: 1) 50-55 mph (85kph) 2) 72v-96v 3)...

Aloha, this is the Hydraulic setup. http://www.ebay.com/itm/PROMAX-DECIPHER-FRONT-HYDRAULIC-DISC-BRAKE-BIKE-PARTS-CBP824-/291884313469?hash=item43f5a92b7d:g:hVYAAOSw0UdXvckf and this is the pad that it takes...

Aloha, all. a couple of questions on my hydraulic disc brake pad setup. (pads are the smaller round ones, Avid BB5) 1: mine start to squeal after about 80 miles and I have to take them apart and file a bit of the glaze off the pads. is this normal? 2: What kind of life do you get out of a...
