If someone wanted to test 300 - 400 NICAD or NIMH cells for capacity, how can it be done efficiently? I do not want to take 6 months charging and discharging one cell at a time. The purpose of the testing is to match cells so as to build a large battery. 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)
