Re: Building a light ebike with Q100 motor : advices ?

Hi Docw,
By "balance" you mean equalizing the tension during charge and discharge ?
Why do you say there is no balance function ?
A BMS is clearly made, among other things, to balance your cells. How do explain the connection of this BMS to each cell if there is no balance function ?

I found the info here: http://lygte-info.dk/review/batteries2012/Common18650comparator.php to be very helpful. After you've selected the cells you'd like to compare, there is a link to read the full review of the cell. For example, here's a review of the LG MJ1 which I'm using in my packs. From thi...

Re: BBS02B 48v contoller on BBS01B 36v

Hi
I’ve replaced the 36V controller of my BBS01B by a 48V controller for the same reason (pedaling rpm). It works well, I’m using a 14S battery.

If you are SO SURE that solar energy has no future, don’t forget to explain it (with better arguments) to the majors like Total, EDF, Eon, and many others, who invest heavily in the sector ;)
