Hey guys, as I mentioned in the title I have a problem with my charger: it keeps overcharging my batteries.
A couple of years ago I decided to purchase a high level charger with twin output to charge two batteries at the same time, and after considering all the options available on the market I decided to go for a brand new Team Orion Touch Duo V-Max.
It worked great for the first few months, then it started overcharging.
After a full charge cycle, the battery cells (sometimes just one, sometimes all of them) read a voltage higher than 4.20 volts. In the last charge, one of my Kraton's 3s batteries read 4.27, 4.24, 4.35. The weird thing is they are also heavily unbalanced, even if they are ALWAYS balance-charged.
Why the hell does it do that?
All of the safety features are active (overvoltage, overheat, security timer...), and the overvoltage cutoff is still set at 4.20, and yet at the end of a charge it still reads higher.
I always double-check with a voltmeter, and it gives me the same measurements as the charger, so if it can read that it's going over the value of cutoff, why doesn't it stop?
I should add, the batteries I charge are 3s Turnigy Nano-techs (4 of them) and a 2s Turnigy Nano-tech Ultimate for my Losi scte. I used to run a 2s gensacearespammers hardcase in my Losi, but it got ruined to the point of being unable to sustain a simple 5-minute bash session. The charge rates vary between 0.5 and 1C.
Does anyone have any tips on how to deal with this problem? Anybody with the same charger that can give me a tip or tell me if they have any issues as well?
Thanks in advance to anyone that wants to chime in.
