I've recently finished my first e-bike build. It turned out great. However, I've now run into a bit of a problem with a balance lead. I was going to balance charge a couple of the LiPo packs in my battery, but one of them created some sort of "short" when I tried to connect it to the balance board coming from the charger. I had hooked the battery up to a Cell Log before connecting it to the board, and everything seemed OK. However, once I put it on the board, it created a mini light show. The voltages on the charger seemed to be reading, but it sparked again when I tried to re-seat the plug. I decided to quit there and see if I can find out what in the heck went wrong.
I've attached a picture. As you can see, the parallel board is going to need some repair. And here I thought I had this whole LiPo game figured out! Maybe I'll be the next one to have a big fire. If anyone can tell me what in the heck I did wrong, please let me know. The main battery leads weren't even connected when it sparked. I was just connecting the balance leads. The negative lead going to the parallel board was connected, but I don't know how that would affect the issue since nothing was even connected to it. I thought I remember reading that it was the proper order (balance leads, battery leads, parallel board leads). Maybe I should go back and re-read the manual. The charger is a Thunder Power TP1430C. At first, I thought I may've put the plug in backward, but I had actually tried it again (the right way) and still got the same result.
If anyone knows what went wrong, please let me know. I had a fantastic time riding the e-bike around, and I was looking forward to riding it over the holiday. Thank you for taking a look at my post!
