Hello everyone, I've bought KOKAM Li-Po 7.4v 720mah and installed on my x4. The result on load was good.
The withdrawal capacity of this batt. is 8C. Big discharge seems to have eliminated the problem of ABC Crp.
And the size is perfect, light weight, with no crp problem. So this is what I've long wanted.
Thank you for everyone, and especially Kyle, you've helped me very much.
And I reported it on my website.
