I've got two 280ah cells that were left for a year at a high SOC. Last night I hooked up this EB tester for the first time and was able to start discharging one of the cells using the 'Single Test'. I let it go at 20A for 20 or 30 seconds. I was satisfied this thing works so I stopped it and shut the EB tester off then disconnected the cables with the intention of doing my first capacity test this morning.
So this morning after booting up the EB software and connecting the tester I loaded the saved batch parameters I prepared the night before. I hooked up the 10awg cables and clamps to the appropriate positive and negative terminals (and double checked that). Also the voltage leads are to the cell terminals as well. After pressing the start button the fan starts up and stops instantly. The software keeps running but the charger does nothing.
There is a red blinking box beside the connect/disconnect button which I'm not sure if that means there is some kind of communication error or if this means its connected?
I think this means there is a data connection.
I've tried two other USB posts on the laptop with same results and also the wife's laptop with same results. I took the PC cable (round plug) apart hoping to find a broken or shorted wire as there is essentially NO strain relief on the cable but it looks fine.
I hooked up cell#2 same results.
I tried a resistance test which also seems to fail without results but the fan does stay on for ~1 second.
Here are my batch settings (have also tried 'Single Test' charging and discharging at various amperages down to 0.01A and it still does nothing):
I tried several reboots of both PC and EB tester, uninstalled the driver and the software and reinstalled both, tried it and same results. With almost nothing left to try I tried updating the firmware (which was already current) which also made no difference.
I read someone had trouble with a board but this thing literally worked fine last night for 20 seconds before i turned it off. I reached out to the vendor so I guess I will see about that.
Anyone got any more ideas or experience this type of issue?
**edit - after figuring out how to use the control panel on the front of the tester I eliminated the PC connection all together but the problem is still there.
