Fried battery electronics...

[MrChef]

So I had a mishap while futzing with the Tigger earlier this week. I wasn't paying attention enough to sparky metal bits touching other sparky metal bits. Got that sizzle sound and some smoke and all went dead. I had thought that I fried a brand new board but after testing it turns out that all the board and all components are indeed fine but the battery itself is showing an error code on my charger saying that it is incorrectly connected when in fact it is connected properly. Soooo fried.



The battery is about 8 months old with at most 5 full charges on it always properly balance charged. I'm assuming the electronics are fried.

Anyone have an idea if these can be serviced or fixed? And or where you'd send it?

Another Tanker buddy said they're warrantied for a year and that MotionRC where I got it from may replace it so I'm gonna check that out. But I'm curios what the hive mind thinks and might share.

My guess is that there are no electronics in that pack. There is a balance connector, but if it's like a lot of my Li-Ion batteries there is no balance board. My guess is that one or more cells in the pack is/was internally shorted and the charger has detected that.

Those are 18650 cells and fairly robust, but if a lithium cell is bad, it's a matter of replacing the cell. Being a 2S2P battery means that it's a 4 cell pack. There are two sets of two cells wired in parallel and then those two sets are wired in series to each other.
