Wow…daggum, nice review…thanks!

Thanks. I have a few more to publish through the weekend if I can find time between getting ready to move.

I like your spread sheet layout at the top. It gives lots of info thats easy to read. I'n not sure the battery dimensions are quite right though. Thanks again for the effort.

It's the rare and mysterious 50500 battery. :D Thanks for catching that.

TY for the review. Seems good up to 10 amps to me. After that the cells track differently.
