Re: 20 li-ion battery doesn't reach full charge.

Anyways, since I just got it together in the last week, when I charge the battery the charger shows 84v on the lines but the battery has never reached over 78v at startup. What exactly does "at startup" mean? I would assume that the 84v means that at the end of charging, it is resting at 84v before...

Re: 20 li-ion battery doesn't reach full charge.

I tried this, thinking there was a voltage drop somewhere, but my potentiometer on my throttle is surprisingly accurate. Only off by 0.1v. I don't understand what your throttle has to do with the battery voltage or the multimeter being used to measure the battery? You should make sure first that th...

Re: 20 li-ion battery doesn't reach full charge.

0.1V is a lot Break down the pack, divide and conquer troubleshooting Identify 20 good matched capacity cells, get close to balanced and reassemble a string to thoroughly test the BMS.

20 li-ion battery doesn't reach full charge.

My baby is finally all put together. If anyone somehow remembers me, this has been a 3 year project for me. I built the battery myself using a vuzrend kit and 140 VTC4s brand new from a vendor I found on this forum. Battery is 20s7p and broke in to two 10s sections that are houses on either side of ...

Re: new cyclone 3000 w mid-drive kit?

Hello again everyone! It's been a while since I've posted. My Cyclone 3kw ebike project is still a project at the moment. I'm going to be ready to order a BMS and assemble my battery in the next few weeks. Balancing my funds has been tricky but at least this way I'll get to enjoy and test it all spr...

Re: Homemade Battery Packs

Hey all, I have 140 18650 cells that I plan to configure in to a 20s7p battery. Since I'm using 7p, I'm thinking about using 2" - 2.5" ABS, or Polycarbonate tube to house my batterys. Depending on how snug the fit is at 2", I was thinking about wrapping the batteries, or lining the tube with either...

Does anyone have recommendations for non consuctive material? In the form of matting
I want something like a yoga mat, that can compress a bit. I'm planning to use the material as some what of a spring, in order to compress my battery contacts together.

Tha ks for your time and calculation..

Correct, and your cass...

Re: new cyclone 3000 w mid-drive kit?

The luna kit says 7 to 1 gear reduction..i thought the motor was 6 to 1 ? Are they exactly the same motor as on the cyclone site? Their site says it's a 6:1 on one page and a 5:1 on another page. Someone on this thread calculated the correct value. Based on the tooth count it's something lik 5.3:1 ...

Re: new cyclone 3000 w mid-drive kit?

Why limit the purchasing to only Luna or Cyclone direct? From everywhere I ended up visiting, luna has a really good price for their kit, and you continue to get good discounts when you upgrade parts. For example, the kelly controller Luna offers is a kelly kbs72121x, this controller is a $90 upgra...

Re: new cyclone 3000 w mid-drive kit?

Yeah, you should definitely research the Samsung 25r. I really feel that it is the best for high-current use. The other cell I would consider is the 30q, but its voltage drops off toward the end. Study the discharge graphs. http://lygte-info.dk/review/batteries2012/Samsung%20INR18650-25R%202500mAh%...

Re: DIY assembly kit for 18650 without spot welding/Solderin

The USA seller told me that the V1 version is rated by them for about 2.5 amps per cell. I am waiting for V2 because I need about 6 amps per cell as a max draw. I must have missed the post(s) about how to raise that number for the V1 version. Do you have a link to information about that? It's actua...

Does anyone know how well this:
http://www.ebikes.ca/product-info/cycle-analyst-3.html
Works with the cyclone 3kw, or the KbS72121x kelly controller?
It sure seems to do quite a bit for you. Maybe it's better for people with one of the 'stock' controller that would come in a kit?

Re: E-Bike won't start (sometimes) - any help?

Does your controller have starting throttle protection? Maybe your throttle sensor is sending a signal to your controller, and the built in protection is stopping everything so you dont lurch yourself off he bike or pull current before everything is ready and all your curcuits are charged.

Re: new cyclone 3000 w mid-drive kit?

Those cells are a great price, but I had a hard time finding what kind of current they are rated for.

Buying cells with good data, ...
