Thanks for the explanation. Those are some very good ideas.

Thanks for your suggestions. I will take a look at some more postings

I plan on adding in parallel a slide variable resistor to create a cruise control of sorts. I am getting a ton of pain in my arm from holding my throttle. When im on my 10mile commute I want to get started from a light and set the slider to assist. It looks like i just need to tap into the...

I am building a large pack and was hoping for BMS recommendations that people have had success with. My bike is 48V 1000W I am building 2 24V LI-ION packs to put in series. Each pack has 12 18650 1800mA batteries in parallel (6 sets for 24V). So the packs should be about 21 amp hours. I would...

I have the same issue with my PAS, it is way to fast for my needs. I was thinking about replacing my thumb throttle with a linear resistor to control the sped. I want to just set it for pedal assist. I can just engage the brakes to turn it off, or mount a big e-stop button..LOL

I'm using the Imax B6 and when it hit 4.10V it stops charging, and I have found If I wait an hour the cells will all balance out. When building my battery packs I will most likely single these out since i want the packs to balance well. This makes sense now when I built my first initial pack to...

Thanks for your suggestions. I am charging them in parallel and after i unparalleled them is when I read the 3.8v right after being disconnected. I charged the cells up to 4.1 separately and im going to try and recreate the issue.

I'm new to this but researching this topic has gotten nowhere. I am using an Imax B6 set to 1s @ 5 amps. I am charging 6 18650 cells all in parallel until the voltage reads 4.1. When i pull them off the charger and check the voltages of the individual cells some are 3.8. Im starting off with...
