Hi All,

I have to renew my battery stock,

I have doubts between a pack made of:

1. 4+6 cells 20C – 1,240 gram
Rhino 4900mAh 4S1P 14.8v 20C http://www.hobbycity.com/hobbycity/s...0C_Lipoly_Pack
Rhino 4900mAh 6S1P 22.2v 20C http://www.hobbycity.com/hobbycity/s...0C_Lipoly_Pack

2. 4+6 cells 25c-1,226 gram.
Rhino 4900mAh 4S1P 25C http://www.hobbycity.com/hobbycity/s...5C_Lipoly_Pack
Rhino 4900mAh 6S 22.2v 25C http://www.hobbycity.com/hobbycity/s...5C_Lipoly_Pack

I would like to hear pros and cons opinions about using:
A. 4+6 cells (lighter then 5+5 cells).
B. 20C versus 25C.

Thanks in advance,
Isaac Najary
