> 6S 4000mAhr is getting seriously into "do not fuck around with this" territory. yes indeed. I've recently been involved with the design of some fairly large 18650 and 21700 cell based battery packs for designs that closely approach the manufacturer datasheet rated maximum continuous amp draw per cell. my main message for the people who use these is the following: "any sufficiently advanced battery in serious amount of energy storage, becomes indistinguishable from a bomb or incendiary device, if you look at it from the point of view of watt-hours stored per kilogram of mass"
