Home-brew battery measuring station

[hoober]

I've offered to test batteries on a few forums before up to 500 watts. I have one cc-400 and 1 cba that is paid for already. It produces nice repeatable graphs , but no-one seemed interested enough to send me any packs.

I know you like to invent/engineer/build stuff , but my point/question is how much are you looking to spend on labor/equipment? This set-up seems available for about $1 per watt, maybe $500 total and can add multiple cc-400's at about the same $ per watt.

I figured it this way: I had already paid for the test equipment and didn't want to buy batteries. I thought perhaps users may send battery samples, but shipping twice really comes close to some of the battery packs I'd be testing. So then I'm left with simply buying the packs myself (packs I don't need)

We've talked about standards too, I can't remember which forum. I kinda like testing single cell for direct comparison , but doing "packs" seemed to be the choice of many users even though it requires 2,3,4,5,6 times the power.

Looking forward to the results here for sure. Someone send me a "test" pack, so I can pull the equipment out of the box ,lol. I don't think there will be any credibility issues with your testing/graphs/data/info Brian.
