Unmatched MAH

[Memoriesman]

I have a specific question. I received a Flitepower 6s 4900 25c battery as a door prize. I already had several Flitepower 2s 5000 25c batt. Can I safely and successfully connect a 4900 to a 5000 in series to obtain 8s? This would be for an S/T mono. Thanks

I personally wouldn't, one pack will drain quicker than the other and give you unmatched voltage. Some people have done it in a pinch, but I wouldn't.
