Havent been around for a while, as I was testing out the truck. The kelly kdh 9500 quietly died(no smoke or full on, just quit). My range was another problem, so I did some load testing on 8 75 ah batteries. I hooked each one to the motor, and used a voltmeter and my amp gauge, and this is what I got. 6 of them ran the ADC 9 for 25 min average, at 45 amps. starting voltage was 12.5 and ending was 6.5. battery recovery was back up to 11.3 in a minute after running for 25 min. 2 of them went flat in 17 min from 12.5 to 5.5 with poor recovery. My question is, are the 6 working properly, or are they all shot? I was only able to get 5 to 6 miles to a charge. any thoughts? Watt
