If I accidentally deleted my bq3055 chip info, but I have it saved on a file can I rewrite it back on to the chip or if I have several of the same bms can I copy it from them and load them on the chip that I deleted it off of ??

I need to replace the Phantom 4 motherboard

laarnova — Fri, 27 Mar 2026 05:48:44 +0000

Hi, I have a Phantom 4 battery with 8 cycles, but the drone is showing a battery error and won't take off. Everything is fine in NLBA. I also have a Phantom 4 battery with 136 cycles that works fine, but I need to replace the circuit board. Can I do this with the 8-cycle cells? After replacing them, will it still say it's a genuine 8-cycle battery?

Thanks

Phantom 4 battery LED light problems

Hello
What could be the reason why, after unlocking a Phantom 4 battery, it works perfectly, but whether it's at 10% or 100% charge, it always shows 3 LED lights?

This happens to me both with an external charger when charging the cells and with the original charger.

(Before unlocking, all 4 lights were on.) Thank you very much.

Plate replacement

Hello
I bought a Phantom 4 Pro battery (new on eBay) knowing it was locked, but the problem is the circuit board isn't working. I need to know if I swap the circuit board from another Phantom 4 Pro battery, will it show 0 cycles or the cycles of the old battery?

Thanks

Hi, I have a question about how to connect the Mavic Pro battery to the NLBA. The battery is over 12V and no lights are coming on. I need to know if it should be connected like in photo 1 or photo 2?
Thank you very much

Hello, I have this Phantom 4 battery that the software and NLBA say is not locked, but it doesn't turn on or give any signal, and its voltage is fine (I also tried reset + GND on the board). In no case do the battery lights come on.
