Best on Test
Ovonic Rebel 2.0 6S 1400mAh 22.2V 150 C Lipo Battery with XT60 Plug
This pack is at the top of the Ovonic Range. It lives up to it's rating providing enormous power and great energy density. Hard to find right now but a great performing pack.
DOGCOM MCK 1380mAh 160C
A larger pack with excellent burst performance and good energy density but a little on the heavier side. DOGCOM have good results in my testing so this is another solid option from them.
