Molicels are High discharge & huge capacity but there are others In my 1st pack I used Lishen 21700R
36Throwback to the First Battery I ever made, I went with an alternate cell that saved me Big $$$ as I got them on sale on Black Friday for 1/3 the Cost. Now even tho I've never ever built a Battery I've built far more complex electronics like amplifiers ac and dc. Solid state and tube high current amplifiers and high voltage complex equipment. A Battery is really simplistic, as theres nothing complex to a battery build at all. Its more about using premium materials that can transfer power with extreme large amount of current flow while being safe. Dont take any short when it comes to batteries use BMS to monitor voltages and thermistors to look at pack tempter. Very crucial in the summer as packs over heat and heat is the batteries number 1 enemy. This Pack did very well, It was sold later as
