Well, mine was wired up and rocking for a few days. Then the 3rd cell would not read in escribe so I touched up the solder and all worked for another day. Now the chip will power up on battery but error message of "check battery" and I get no reading from the battery in escribe at all. Checked all solder points and everything seems legit, no visual issues I can spot. Any advice? Thinking of just desoldering (a true pain) and reattaching everything. Maybe aim the balance board down to save space if the error is due to interior clearance, which it is tight in my 3d printed case but I don't. Know. Haaelp
