I do not ever want to find myself in that position again. It hurt. Not where I thought it would - the very tip of the skull. Felt like I was wacked with a piece of rebar. I really do want to keep fooling around with this stuff. But I use mechanic's nitrile gloves or medical exam gloves. Either gives good protection against 120 vac. I do have to laminate the work area deck with plywood. The super warm temperatures make going barefoot tempting. And tile or concrete is a dangerous conductor.
Might as well add this...
Even 12vdc can burn tender skin. Make an optimum negative contact with sweaty skin then complete the circuit again with salty moisture and a 1st degree burn can happen on inside of wrist - forearm - cheek - etc.
Back to testing. Use a cellphone ET for timing. That DROK 4-1/2 digit voltmeter is priceless for stuff like this. Use a DMM ma scale to qualify a shunt. Again a 4-1/2 digit DMM is worthwhile. I have the assortment module of 5 resistors in a bar in a case. All 5 are 10 ppm accurate. Curious error in DC voltage vs resistance seems linked in all my DMMs. I also have a handful of 8.1000 volt qualifying zeners. I'll see if I can get some to you Jeff. They are fun to play with.
My interest lies in factoring watt minute performance of a battery. LiPo wins hands down. Nothing else is even close. Take a 316 ampere hour L16. The Rolls has much higher voltage at a 150 amp draw than say a US battery of similar A/H. Factor cost per kWh transacted and a few surprises are in order. My big bank has had it easy for going on the 22nd year. The L16s in Quicksilver were installed in 1998 and have subsequently lived The Life of Riley. The frame is on pylons to ease the load on the tires. My son in law is good with that 22 air over hydraulic jack. The engine PT drive has a huge York compressor.
Wouldn't it be great to see tests between whatever battery Costco is vending versus a Trojan? Or an Odyssey versus a Lifeline?
