so two weeks ago my battery pack zapped me while I was wiring in the last 1s16p bank into my system. 64 CALB cells in a 48 volt setup. As they are not new and repurposed second hand cells load tests show me they have a capacity of 185 (avg) vice the 200 they would have as brand new. that's still over 700 amp hours or 38+ KWh available.
so I was sweating my backside off and hooking up BMS leads when I sat back and my left forearm made contact with the primary positive and negative buss bars. got the zap feeling jerked and my pinky finger and part of my forearm has had pins and needles feeling ever since. figure I did some nerve damage there.
I know, blah blah blah... waiting for all the snide remarks. normally my bussbars are covered with a plexi panel I made but as I was hooking up the latest pack I had removed them to facilitate the install and was not thinking.
now at 55 this just means its easier to give myself a numbie without the need of sitting on my hand for 10 minutes ... but it could have been truly serious. the big question is will the pins and needles in the pinky finger go away or is it a new reality for me.
