Re: Motors/Battery life

Gene,
We are running tests on all of our batteries (some going back to 2002). Using the CBA II at 7.5 amps, we test down to 8 volts (the cutout for the RC). The computer then allows us to overlay the results and I will be printing those up shortly. It takes a few hours to run the test so we don't want to leave a battery on test when no one is present. Interestingly enough, we have another battery that has diminished cell capacity on one cell that obviously reduces by 2 volts during the test. The CBA also calculates amp hour ratings from the test.
