Battery not fully charge vtbox200

Looks like a bad cell 3 (multi metre readings will match EScribe values) or bad connection to the balance connection (the cells will measure correctly on a multi metre) for that cell, really you should return the mod or battery.  To measure the cells with a mm start at the negative side or the 4 pin connector with the black probe on that side and the red in the adjacent pin for cell 1, then move them both 1 space up for cell 2 and both 1 space up for cell again for cell 3.

Obviously you have an extremely unbalanced LiPo battery, and while you can get the battery balanced it's safe to say you have a bad cell. I'd first recommend you RMA (return) at least the battery if not the Mod. If not then I'd recommend a new LiPo. To balance the LiPo you can either discharge the two 4.2V cells to around 3.8V or charge the 3.8V cell to 4.2V. I would not continue to use the LiPo until it's balanced. Certainly, you can leave it on the 'charger' until all three cells are fully balanced, it's going to take a while. I would change the Charging screen to show Cell 1, Cell 2 and Cell 3 to make certain it doesn't overcharge the pack. Here's an excellent video: https://youtu.be/wIbHLacozFo

I had the same problem with mine and I replaced the battery with a new battery(as suggested by Gear Best service). When I pushed the fire button all looked fine. Then I put it on e-scribe to finish charging the new battery And instead of charging it drained the new battery to a dangerously unbalanced state. I have since sent it to Evolv for evaluation and possibly repair. Good luck I know how frustrating it is to be in your situation.
