Hey thats cool!! I wanted to do a load test on my GC2 batteries when brand new and then throughout their life. Plan was to do something like a 20a load and monitor voltage drop on a fully charged battery. That works well (not at fully charged) for lithium batteries found in RC toys. Not sure if its a good test for a flooded lead battery though.
