Hello everyone. Been doing my research through everyone’s posts and decided to add some of my own.
I made this cool spreadsheet of the best performing 18650 battery cells for high current draw (140-150A). The information is based on tested reviews found on the following website:
The total cost is based on reaching 140 or 150A continuous discharge rating with a 12S voltage.
I hope this helps.
Edit: Added an updated spreadsheet which aims for 200/210 Amps instead of 140/150. Also includes a premade R/C lipo battery.
