So I am starting a small project first before tackling a power wall in order to get a better grip on 18650 usage. AND, I'm all ready confused.
I'm building an external starter (one you hold in your hands to crank a motor). The company recommends 2 deep cycle lead acid batteries in series for 24V with 900 cold cranking amps, so i wanted to do with 18650 harvesting and going through the whole process to learn.
So my question is, do I need to build a battery with 900 Ah rating, or can I use the C rating (max discharge) of the cell since it will only be a short couple second burst? OR is it something that as long as I have the equivalent watts, it should be good? For example run a 36 V battery instead of 24V?
Thanks for the help. Watched tons of YouTube videos and can't seem to get this answered. Love the projects!
