That was my first thought. That's where the value of 1-6 amps came from. 1 amp when it's murky, 6 in clear sun. Probability capable of a little more than that in ideal conditions.

I have a 100w solar panel I'm trying to use to charge a lifepo4 battery. On my e bike I used an ebay special voltage converter to drop from 36/48v down to 13.8v to run "12v" things and it worked great. This was for things like a headlight and car style accessories. With the solar panel I'm...

I previously ran a motorcycle battery made of lifepo4 a123 cells that worked well but as a project was not fitted with a BMS. I'm revisiting the idea, but this time with a BMS installed. With these BMSs they usually have one negative wire for charging and one for load. If you were to run this...

After quick testing with 2 other controllers and a motor, it appears to be a motor issue. Now just have to get the thing open to see the extent of the damage. I think it's a phase gone down or possibly a sensor.

I've been attempting to increase the current limit on my con93 controller (generic Chinese). It was a 9 fet 18 amp controller running @ 37v (42 fully charged). I upped my battery to 58v fully charged and was getting 1150w peaks. The battery is hobbyking lipolys capable of 160 amps but bms...

Is this how LiHV works? Some random cells in the batch can take a higher voltage without issue and so they report them as higher capacity/higher voltage. On the other end of the scale, in large battery packs (such as electric cars) you have to design around the lowest common denominator. So...

I've been using a voltage regulator to supply power to my lighting setup. I've seen some on ebay but I can't quite figure them out from the translated english...

I've bought a smaller power supply from ebay that I thought I might be able to use as an on the bike charger. It turned out to be this one: http://www.dss-power.com/cn/ShowProd.asp?id=137 Currently it provides a voltage across the terminals of 42.4V. The seller assures me this is correct as...

I've been looking for reviews or experiences from people buying from Sun Rise Int'l (http://theebikemotor.com). I can't seem to find any, either here or through google. Has anyone had experience with them? They seem to have a range of what i think are Q11 motors which appear decent value...

The motor connector is pushed all the way to the line, and works fine with my other controller. The controller to motor cable is 3x 3 or 4 mm bullets which are fully together. I checked the crimping on the bullets and it all looks well made. I checked mosfets as per ebikes.ca guide, and they...

I'm having trouble with a new Con 122 controller. Wondering if you guys might have had similar issues or any ideas I was running on a con 93 from green bike kit. The bike performed well with no issues. I connected this new controller with just phase, hall and throttle connections. The wiring...

I'm having trouble getting my PAS to work. I've get pretty much everything else on the controller working, but this just won't kick in. I'm using the CON93 controller from greenbikekit.com with a 12 magnet PAS. The connectors that came fitted to them match. The controller has a red, black and...

I need some help in determining the power requirements for a slightly different water vehicle. There are some guys at work looking to take part in a homebuilt rafting event.There are about 10 people taking part, with the home built raft (not yet built) probably totaling around 1250-1500kg in...

Just an update for anyone who find this in search. I tried a third option, which worked for me, may not work for you. I bought a brake disc off of ebay for £8 to play with. I talked with a guy at work and we thought it was doable to get it to fit, with some adjustment. The disc had relatively...

I'm currently trying to put together an electric bike using a cyclocross frame and a q100 cst motor. I chose it partly because it's fitted with dual cable disc brakes. I'm having an issue with the disc brake mount on the motor. Where the disc would mount, it would protrude into the mounting...
