Thanks! First I thought that I use lipos but there is few problems with them:
-Wires. There is a lot of them if you are using for example 4x 3s lipos.
-If you are using only two lipos for example 2x 5s they are too thick.
-Also some lipos tend to swell
I went with 18650 cells because I can build a pack with the size I want. They are safer and wiring is not such a hassle. Plus they are only 18mm thick!
Hey!
I’m going to be building on the same deck as you, and I was wondering if you would think of selling me the enclosures?
Think i’ll copy your 18650 idea as well, looks awesome!
Really nice build! I’m interested in setting up the same battery on my build and was wondering how it is all wired. Specifically where do you connect the balancing leads to the batteries and why are there 6 balancing leads for 5 pairs of batteries on each row? Is one just connected to the ground wire? Any pics before you wrapped it? And lastly what kind of real world speed/distance are you getting?
There is 6 wires in JST connector because 5 of the leads balance the cells and one negative (the red wire)
Sorry, I forgot to take any pictures during assembly, but I hope that the picture helps!
I have tested the board in parking garage and with gearing ratio of 14/36 I think it will max 40kmh. I will post real results when I am able to ride outside. Battery is 185Wh so theoretically the range will be 18,5km with one charge.
@Dunkirk Could you give a diagram on how you discharge in series and charge in parallel without removal of your enclosure? I’m confused as to how you have wired everything. Thanks!
