    Battery or charger issue

    Here is the issue, 6th cell of 6s batteries is over charging to 4.29 volts. How bad is it, could I get a few important flights in without damaging it? Feel free to ask any questions. Thanks

    Lipo Battery Short

    So I was flying the drone and the balance connector went through the rotors causing some of the leads to short. Seeing as I need a new set of underwear after the experience do I need to buy a new battery aswell? All the cells are at a good voltage - about 3.7V each so can I just resolder them...

In total it will have been at 2.7V for 3 weeks and I have no way to charge it until my new charger turns up. The...

    Lipo battery help

    Hello everyone, I’ve been flying for a bit on 5s batterys and it’s nice but I wanted something more casual so I picked up two 4s Tattu Rline version 2.0 batterys.

I now have very few original parts on it and subsequently have learned to...

    Which one is better?

    Hello, people! Ordering bit by bit my racing equipment (as well as a prebuilt drone) and batteries got me confused a bit. This is my first proper experience with RC world and I really don't want to fail at it and go through as smooth as possible (no pun intended). As a beginner, I tend to...
