Sanyo 20700B 4000mAh 20700 Bench Test Results...a peek at the future?

[Mooch]

well that explanation makes a massive difference.. Thank you.. I get it now, and what you mean by the crossover point compared to other batteries. So obviously for someone like me who just want massive battery life for tottling, 30 watts and under (15 w per battery) would be absolutely ideal for me to get the 20700b, yes?

Yes

A quick question with the 20700b batteries. Is there any way to calculate the current draw from a regulated mod like the Captain? A build of .31 ohms at 65W shows around 14.6A on the screen and I assume that is the output from the chip to the coil. What would be the current draw from the 20700b's, or would it actually have to be measured?

65Watts/(cutoff voltage)6.4=10.16A assuming de efficiency is 85% 10.65*1.15%=~11.95A if im not mistaken

Thanks, that all makes sense after reading Mooch's blog entry!

Thanks, Kudos for all you do for the vaping community!

I think I got the formula down... think being the keyword lol

If I ran these batteries in the Captain at 35w Id be drawing 10.9amps so we'll say 12amps with the 10% margin of error added in... Am I even close to being right?

I'm looking for max capacity at a safe level, and run a .7ohm single coil at 35 watts or less. So these should work adequately and safely?
