I shorted my battery (with a spanner) from the battery fuse to the negative bus bar of the lynx distributer (see red pen) just after the shunt. Note the black cables with red heat shrink are positive cables. As such it was a short across my battery bank (not through the fuse or battery switch). There was a small spark/noise, the spanner was metal no insulation, my lithium batteries are inactive and had 0V across them prior to this, I didn’t feel any zap, the spanner and nut both have black spots and the spanner was somewhat welded on. How do I test my batteries aren’t f$@&?! given they are inactive and I need to charge them first? I was hoping by the fact that I didn’t die, the spanner didn’t melt that maybe the batteries have a self protect. I thought I read in the renogy manual online that if they short I just need to reactivate? Which needed to be done anyway. Anyone know or had this happen, they are brand new, it was a very careless mistake that I was wary of not doing, rookie error
