Does not charge at 10 amps on all batteries

I bought this because I thought it would be an upgrade to my current 6 amp charger. As I recently got a big 10 amp battery and wanted to be able to charge it faster than 2 to 3 hours. This charger won't do it. On a 6S battery it will only charge at a max rate of 4 amps for some reason. Even though my other character will charge a 6S at 6 amps just fine. So this one takes even longer than the charger I was trying to replace. The only thing that caused me to give this charger 2 stars instead of 1 is that the fans are a nice feature. My 6 amp charger doesn't have a fan and it gets really hot when running for a long time at 6 amps charging that 10 amp battery. This one stayed mostly cool due to the fan (plus it only charging at 4 amps). I'm disappointed, they should specify this charge rate limitation on higher cell count batteries in the description IMO. I'm most likely going to return it due to this omission.
