So far I’ve just been using the basic obd2 Bluetooth things but the apps available are very limited. I’ve been able to do some custom PIDs for some of my vehicles, and others you can often find tools that allow you to do some specific programming but it lacks a lot. I’ve been considering some of the ones you can find for around $400 from China but I’m not sure if those are anywhere near the same level as the 10k snap on ones.

mAh/Wh is just the capacity of the battery, and it’s often exaggerated or just plain incorrect on these cheap mass produced batteries. So battery life may be slightly different than intended for the product but it won’t cause any issues. As long as voltage is similar(all lipo batteries are 3.7-4.2v, some manufacturers label with 3.7, some with 3.8, etc. But all cells of the same battery chemistry are the same voltage range) it’ll operate and charge just fine.

484588 is the dimensions of the battery. So 4.8mm thick, 45mm wide, 88mm long. Any lipo that fits in there will do the trick, but obviously similar size is best. You should be able to find something similar on AliExpress; it would help to round the dimensions to a more standard number. For example, search “504090 3.7v” assuming a 5x40x90mm battery would fit in the cavity.

Fair enough, I guess I just end up needing to fix things for other people way more than the average person. And more often then not, a multi tool saves me a trip to my car tool box. Its mainly just the blade, and pliers that get a lot of use. But the scissors and file get used quite a bit, too.

I’m almost curious what kind of life you live? You never find yourself in a situation where having a knife, screwdriver, pliers, or a flashlight on you wouldn’t be a huge convenience?
