Hi well i was looking at large power-supplies in general and hoping to find a good variable voltage supply, then i wanted to build a current limiter in, i didn't like the idea of fast charging the cells all of the time, especially if they had just been used. I thought it would be good to slow...

Thanks for the input Fechter, it is starting to make more sense to me. It could be a bit of a gamble buying an old industrial switch mode powersupply but i guess there is always a way and hopefully i would get there eventually. It's just i'm not sure that some of the chargers for sale (for...

Hi y'all, i am just getting into the world of e-bikes and although my knowledge of electronics is not bad, some of the people on this forum seem to be way ahead of my level and there seems to be years and years of reading on here. I was wondering if anyone could point me in the correct...

Well i can't seem to load the image but here is where you can see it, look at the BMS's on this page and notice the ones with the missing components http://www.bmsbattery.com/index.php?cPath=3_10&osCsid=49df0f4384bb261e2c928a5f63bffe79 Don't forget, if you get a BMS which can handle a higher...

For some people building their own packs out of separate cells is a good option. At least you will know how to maintain your pack and how to upgrade the pack itself. In case you want to go for more Ah or a higher voltage. The initial choice of the C rating for the cells you are going to use...

Perhaps not everybody fully understands Ah (Amp hours, the amount of hours you can draw one amp or how may amps you can draw for one hour, etc.) and the discharge rate or C rate (how much power or current in Amps your battery is designed to provide at any one time, there is a constant discharge...

Hi This post is to help shed a little light on the complications of buying batteries, i hope it can help some people who know a little less about electronics to find the correct batteries or cells for their task. I would like to start with this suggestion. Don't forget that a battery can be...

Thanks for the insight guys, yea the regen braking will deffo take some more thinking perhaps i'll keep it to one wheel only, two wheels takes some thinking too as they need to spin at the same speed. Thats good to know about the 30A and 50A versions though, i have been chatting with Ann from...

Hi needWheels Well i didn't pay him yet so i guess i will see tomorrow or later tonight what his answer was. I was about to pay 705$ so he has some pretty good motivation to help me out although i could end up with some bad feedback if i don't pay for something! I can handle one bad feedback...

This is the latest email, so so far they are trying to help: Hi James Thanks for your reply I have checked for you. "What i propose is that we find some high rate cells and build a 20Ah pack. If the C rating of the cells was between 3C and 20C constant discharge (depending on Ah) then we should...

By the Way yes i am also izzzzzz6 but i will be using lifeonourplanet as my profile name from now on. I am new on the forum and forgot to change my post the other day to the new profile name. I will be posting youtube videos later this summer to lifeonourplanet on youtube. There are currently no...

Hi i just want to point out a few things about batteries as not everybody fully understands Ah (Amp hours, the amount of hours you can draw one amp or how may amps you can draw for one hour, etc.) and the discharge rate or C rate (how much power or current in Amps your battery is designed to...

Hi Guys, this is my first post on any forum ever :D I am considering buying two of these magic controllers for one bike. I live in the mountains in France (Chamonix Mont Blanc). This is one of the reasons i am interested in regenerative systems. My first e-bike is going to be an off road on...
