Order Number: 701532
Product Name: Thefpv - The Battery V3 (6s, 1200mah, “120c”)
Brand: TheFPV
22v on main power leads but only 11v on balance lead. 6s battery so won’t let me charge it.
Tested on just power lead. Testes on just balance lead. Reset charger that I bought at the same time from yourself. Checked plugs fully incerted. All pins look good and fully seated.
Thank you for reaching out to us and providing detailed information about the issue with your TheFPV - The Battery V3. I’m sorry to hear that you’re experiencing difficulties with the battery and charger.
Based on your description, it seems there might be an issue with the balance lead or the internal connections of the battery. Here are a few steps you can take to further diagnose the problem:
-
Multimeter Test: If you have a multimeter, try measuring the voltage of each cell individually through the balance connector. This can help identify if a specific cell is not functioning properly.
-
Alternatively please provide us a photo showing each cell voltage so we can try to isolate the cause of thee issue, as its odd that half the cells on your battery are dead.
-
Alternative Charger: If possible, try using a different charger to see if the issue persists. This can help determine if the problem lies with the battery or the charger.
If these steps do not resolve the issue, please let us know. We may need to arrange for a return or replacement, depending on the warranty status and our return policy.
Please feel free to reach out if you have any further questions or need additional assistance. We’re here to help!

Thank you for the reply. I’ve measured voltages across the balance lead. Negative on white wire and my results are from cell 1-6 are followed in volts. 3.8 7.6 7.6 11.4 15.2 19.1. Impossible to take photos while taking readings one handed. Do these reading look normal and maybe the battery charger at fault. It only registers 3 cell voltages on the charger and I even made sure it was updated to the latest version. Unfortunately it’s the only charger I have as this is the first drone I’ve ever had. Thanks.
Just had a thought. Please see attached pictures. Do you think the plus has been wired wrong? (possibly assembled upside down)
Hi Rhys good day,
I looked through the video and images, yes, this is a bit odd.
Do you have a second battery you can plug in and check if it behaves in a similar manner?
