Battery comparison
To find the best batteries for our projects we compared the specifications of available batteries on the market. Some of the batteries did we order and test manually.
Below we have different spreadsheets that have been in considerations when we selected the Headway 38120HP cell to gokart 2. Gokart 1 is aquiped with Winston 60Ah.
