I can swap and service most packs without a second thought now, and the everyday jobs feel routine. But when a pack is quietly degrading or throwing heat I can't trace, I stand there staring at readings that don't add up. The slow failures and the thermal problems are still a step past what I can read.
More people experience this than they realize.
You can service most batteries, but degradation and heat problems still stump you.
If this sounds familiar, the Library can help you find the bigger picture.
