BATTERY HELP!!
 

ok so i have the onyx 230 charger and i have 2 nimh batteries , i did all the setting s per instructions but the batteries seem to be charging hot , and my main worry is one battery when done charging only says 3028mah all 3 times i charged it but the other battery reads 48-4900 mah, both batteries a brand new could it be a bad battery>??

What are you running the batts in? Reason I ask, my Emaxx runs one batt down noticeably more than the other - this is the side that powers the BEC and runs the rx and the servos. I run 7 cell pacs that are "handed" so I always see the same batt take more than the other.

Unless you're running them as a pr like this, there's no reason I can think of that they shouldn't be much closer together and I would suspect a batt prob too. When NiMHs peak, they should be hot - 120-130F, but not so hot that you can't hold them.

i'm running them in a salsh but one at a time, my point is when the charger say complete one battery always says 3025mah(its a 5000mah batt.) but the other reads good

Is your runtime the same for both batteries? I've only charged Lipos on my 230, but the number of MAH's you see is what the charger is putting into the battery, not the capacity. If your runtime is different for each batter, that would explain it, if your runtime is the same for both batteries, then you'll have to wait for the experts to chime in.
