Neu4900xp 2s1p
 

Is there another pack I can run in series with this that will not hurt it. Either 2s or 3s. 3s would be better.For a total of 4 or 5s. I found a neuenergy4900 7s1p pack. I could see if Link would make one 5s and one 4s out of the three. I would rather get a 3s pack to run with the 2s1p neuenergy 4900 though.

yeah that should be fine as long as the cells are the same, and they are in similar condition. you cant have 2 tired cells working with 3 new cells.

The neuenergy packs are sold out. The 2s1p 4900 I have has about 6 runs on it. Is there another brand of pack I can use that anyone knows will work? I just do not want to ruin any packs or a rc.

I would say thats a pretty bad idea.

I was'nt sure if it was a good one. I did'nt know if there was another company using the same cells to make there packs.If there was that would work as long as it was the same specs.4900mah 25c
