The fuel table describes the state of charge based on a given voltage. For instance, 4.2 is fully charged, 3.8v is 50% and 3.7v is 20%. These are rough numbers and the actual value varies based on the C rating of the packs.

Because the fuel table is different between a lower C pack and higher C pack, select the value that most correctly describes the pack you are charging. If you want to use a single present to charge both 18c packs as well as 40c packs you can. But I would not use the AUTO charge modes. Instead use a manually set charge rate. The fuel percentage may not be completely accurate for one type of the pack, but often close enough to use as a general guideline.

However, I find it most useful to have single preset for each charge rate that I use. As 18c packs are going to have a lower allowable charge rate than the 40c packs, it just makes sense to break these out to two different presents. Then adjust the fuel gauge for each.
Thanks. Brilliant explanation. I thought it might be something along those lines. Off to do some presets now for the different C rating batteries I have.
Cheers, Rich
