Got it. So bonkas are the best option on the market eh? I might need 10 of them for better flight time lol!
The Bonkas are the best compromise of price, power and weight for the X4 for most pilots. If your ok with launching and landing 22kilos of batteries plus the frame, over 30 total, then there may be other options to consider.
I don’t think I can see that, just poor soldering. And I have not put them through any real load that would have built up enough heat.
Not even sure they were trying with this one, must be working, on a per solder joint qnty per day and if it tested ok they get their money☹️
Two bats re-soldered and now no errors from the charger. Waiting on some Kapton tape to close them back up I think I will only run these batteries at 80% load.
