V12 battery repair
Inmotion showed me how to do a battery pack reset, which didn''t work. I''m not certain but I think the BMS is broken. I was able to charge the wheel to 100%, ride it until battery levels dropped below 18%, then suddenly it started complaining about a broken pack. Up until that point it rode perfectly fine, even up to 50kmh at 20% battery.
V12 battery pack balancing?
Today my V12 forced me off of it (tiltback) and in the display mentioned that not all battery packs are enabled. Sure enough, one was disabled, I assume because at idle it had over 1V less than the other pack. I have now charged it to 100%, the warning is gone, and there''s still a 0,7V difference...

The left (non-board) side will have space below the battery. On the right side, the board and all the cabling is in that space, so you won''t get many cells into there. So unless you start hiding cells in every small opening in the wheel with your own self-made crazy battery pack, probably only 260Wh would work with a normal-shape battery pack.

6 FAQs about [Parameters of the unicycle battery pack]
What determines the consistency of a battery pack?
The consistency of the battery pack is reflected by the statistic characteristics of the single battery cell. The battery pack is usually made in parallel and series by thousands of cells, and all parameters of the battery cells meet certain statistical behavior. 2.1.3. Weight property
What is battery pack capacity?
The definition of battery pack capacity is similar to the single cell. That is, under 25 °C environment, the battery pack starts to discharge in 1/3C rate when one of the cells in the battery pack is in the fully charged state, until one cell has completely released its capacity.
How many cells are in a battery pack?
The battery pack model with 96 cells in series is established. The influence factors of the consistency on battery pack are studied by simulation and experiment. The capacity loss composition of the battery pack is obtained and verified by the temperature variation experiment.
How does the consistency of a battery pack affect the experiment?
The consistency of the battery pack is gradual, so it requires a very long time to the actual experiment. In addition, because of the statistical of the battery pack consistency, more cells are needed to experiment in group. The control and measurement of the single cell parameters will affect the experiment of battery pack.
Why do we need more cells in a battery pack experiment?
In addition, because of the statistical of the battery pack consistency, more cells are needed to experiment in group. The control and measurement of the single cell parameters will affect the experiment of battery pack. The complexity of the experimental study is not operational.
Why is a battery pack equalized?
Therefore, the battery pack is usually equalized to reduce the inconsistency. There are two general equalization methods: one is the dissipative cell equalization, and the other is the non-dissipative cell equalization (energy transfer).
