No issues as of now, but I have a feeling they will stand by their product if I do have any issues in the future. I would say this pack has at least 2400mah of usable power The leads had heat shrink on them to protect the battery.
This is an excleent little battery.As soon as you dump it in the controller you will notice the weight difference and the amount of run time you get out of this using your controller.I have only charged once in 4 race meets.Soon as you pull this beauty out of the bow you will notice it is good quality cause of the packaging but also once its been all unwrapped its just a matter of throwing it in with no modification to the plugs.
I'm using of this on my Ko Helios and it's a direct fit.
You don't need to change anything on tne connector, only plug it with the posittive on the rigth side (looking the TX with the battery comparment near you.
Saves weigth and last a lot.
I used today all evening and the voltage level only drops 0,2v... It's awesome
