Recently for my Vector, I used a 7.4v battery on it. With the mods that I installed, it was too much for the battery and it went poof and what not. The vector just needed an easyFET replacement but that’s all, its fine now. After this unfortunate event we went off to buy deans connectors and a new 11.1v battery. We installed the plugs the correct way and tried to test it. The first battery, a 2000mAh (probably not actually 2000mAh) SKD 11.1v, didn’t work. When we plugged it in, it was like no electricity was coming from the battery. It was fully charged and we had to push down on the battery side cables to get it to work. The second battery, some 11.1v 1800mAh one, did get electricity running to it, but had a different problem - its charge lasts for literally a few seconds. We plug it in, get a few shots out, and its dead again. It also just magically loses charge just lying around. And, additionally, when we plug it in to my B3 charger, when its fully charged only 2 cell lights will go green. The 3rd stays red. This is really annoying as these were my only batteries and now I got none. Do you guys have any ideas as to why this happened?
The mods are listed on this post I made.
