great! a beer cooler it is. gotta look into liquid cooling, i think tesla announced a new system a few weeks ago.

dont get me started floyd. just drank a cup of espresso. i can sum it up: building a house using 90% dirt and 10% cement. the walls behave as a thermal battery. your 18650 powerwall can run your house off grid with no need for A/C or cooling. building with traditional sticks and insulation will...

do you have a fireplace? if so you could build in a rocket heater to burn super hot with much higher efficiency. store the heat somehow without burning a ton of wood.

oh the visual is amazing, and makes sense why i couldnt find any info on this. kinda moot to worry about any 18650 below 3.5v. so im understanding that the low cutoff recommendations are for purposes of not over discharging/degrading lifespan. usable voltage is same for both of my mixed and...

building a small pack to play around with. using battery hookups molicell medical pack 2200mah cells. i have about 50 mixed cells (LG, samsung) with similar capacity to the 50 pieces of identical molicell. i planned on mixing them together and matching capacity in each pack. looking at the...
