Umm, if you've had EV training, I don't think you would be talking about EV batteries like that. It can be second nature and not be a big deal to you, but these batteries are not "nothing." They have enough voltage and amperage to kill you instantly. There's a reason they sell insulated tools and such for working internally on EV batteries. The battery cells are only nothing when they're completely disconnected from the rest of them and not in the pack. Don't tell people they can mess with high voltage without training, there are already too many people online that overestimate their abilities of working on cars, but most of the time that won't get them killed.
We're not talking about LT oil pumps, we're talking about LS oil pumps. This is the 07-14 section.
old thread, sorry for the late reply, missed it and only saw while looking for a towing post. but I can't leave it as you trying to scare people away from battery's.
Yes I have ev training, more than most and I will be getting some of the first rounds of sodium batteries to test.
half my fleet is now ev. no one uses insulated tools. even the warranty techs come out with some black tape wrapped around wrenches. it's fine.
basic knowledge is all that's needed, and a little bit of research to find how your specific pack is wired and where the disconnect is. it's not rocket science. I feel the internet is going the wrong way with electric car info. driving everyone away from learning anything. way more people in shops have been injured from a 12v lead acid battery exploding in their face than ev batteries ever will and we don't tell the average person to go run and hide from their 12 volt battery
here's pics of the stuff I deal with almost daily. new pack came with a random fault in the wiring in the bottom of that rats nest. that's 26 cell 1000lb pack with 2 bms's slaved together. it's a cluster to work on, you're not pulling all the cells out to work on it. it's not practical. you disconnect circuit and then don't cross the individual cells like you would any other battery. reach down and start pulling harnesses out.
like with all batteries, even your 12v car battery. don't complete the circuit by touching pos and neg together with anything.
as for the oil pump, yes I'm talking about an ls engine, not a LT. they did put a variable displacement oil pump on a ls engine( specifically the Hybrid engine being talked about in their thread) and it can be installed on any ls engine across the board, it is completely different from the one used on LT engines. Just like with batteries, just because you don't know it doesn't mean lock down and run away. do some research and don't be scared to work on your own vehicles.
