I think the 4 chargers I have may be wreaking my batteries.
Now I know I don't have the top of the line batteries but I think after a few different brands and many packs, I think somethings wrong.
After any were from 25 to 50 flights the batteries start to drift in voltage while on the charger. They also begin to not balance very well and some times one cell will over charge to 4.28 volts. I'm afraid higher if I leave it. Sometimes instead of the cells going up in voltage they drop and climb and drop and what ever.
This happens with all packs on any one of the four random chargers I happen to put them on. I know the balance connectors and all connectors are ok.
What else could it be but cheap chargers right??
I'm using the four Turnigy Max 200 Watt chargers pictured below.
I am not hard on my helis and fly my Blade 130S with a Glacier .450 mA 3S packs for 5 to 6 minutes.
I fly my 450 for 8 minutes with HK Zippy 2600 mA 3S packs and they get warm and started to puff at 5 whole flights.
These and other brands have the same characteristics early on in there lives.
Oh I only use a 1C charge rate.
After a flight I will only charge the packs to the storage voltage, (3.8/3.82 volts until needed again. The charging time goes from a nice 40/45 minutes to the 120 minute limit and their not balanced.
So what do you guys think? Is it me?
