You are correct. The price is too high. For 7K, I could buy 10 power supplies to charge 10 batteries and 10 battery testers like the Revolectrix Power Lab 8 @ $330 each.

Any tester I can buy to speed up the process? Yea, but you won't like the price. We have a battery tester from Midtronics at work that could test conductance (which accurately relates to capacity) of 400 cells in a couple hours. At least when we bought it about decade ago, the cost was something like $7K. We use it for testing 48 volt stationary battery plants such as this one: https://drive.google.com/file/d/0BwIdhkNRMTaRdnp3U0hNT0xrR2s/view?usp=sharing BTW, that's 3,600 AH at 48 volts -- 73 ------------------------------------- Jim Walls - K6CCC j...@k6ccc.org Ofc: 818-548-4804 http://members.dslextreme.com/users/k6ccc/ AMSAT Member 32537 - WSWSS Member 395 _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA) -------------- next part -------------- An HTML attachment was scrubbed...
