If by that you are referring to the purple efest I have some of them. I would not go lower than 0.3 ohms with a build on one. The 35A on that battery, as I understand it, is the pulse rating. I consider it a 20A battery. Rule of thumb for safety is 80% of constant current rating so in this case that would be 16A. At max voltage of 4.2 V divided by 16A equals 0.2625 ohms (lowest resistance).what one would be better to run on a 18650 35A 2500mah batt?
I have the purple efest 2500, LG 2500HE2 20A, and Vappower IMR 18650 2500 35A. I treat them all as 20A cells.
The VCT4 is an awesome cell!
