I generally use the AH as my "gas gauge".
The way it's setup, it's 0 when the pack is fully charged, and counts UP as you drive. I
know that my "empty" is around 140AH.
Note that it has a couple of relays that can be programmed to turn on/off based
on voltage, current, or AH values.
The OP's messages are not getting to me through the list. Probably a
gmail thing. I wonder how many other messages are not reaching me?
I just bought two those through EVWest:

I just lashed one up but haven't much tested or done a permanent
install. But, it seems to work as advertised. My applications are 36v
golf carts (with ebike batteries). The lash up used a 12v battery to
power the device; I have some DC-DCs on order. I found the instructions
obscure but I think I have it working as needed. Seems like a great
value. Just as John says, a fuel gauge if you have a good idea of your
battery capacity. I've used TBS meters the same way for years. The TBS
is around $200 as I recall.
