Glad I could help! There are current limiter circuits, but they are more difficult. Batteries are not in any way smart, it is more like a team of horses. They will run until they drop, unless you control them! You are the driver, and you have to pull back on the reins, by controlling the load. Then you also have to run the brake, to keep them from running away; by installing a fuse or a breaker.

Have a lot of fun, and I hope you get a lot of free power!
