You're comparing apples and oranges.
Well, Robert, how so? I presented three golf cart packs, each offering
about 100ah of usable capacity. Where did I go astray?
- six T105s would be about $900.
- 12 TS-LPF100s: about $1500 + $300 BMS

Continuing to cogitate on ebike batteries: can anyone give me a good
estimate of the number of ah one can pull from a lead golf cart
battery? I'm thinking my 2 20ah ebike batteries are a pretty good
fraction of a lead pack. Can you keep a lead GC battery alive if you
pull 100ah from it?

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.

I have one of those Watts Up meters. It works nicely, within its
limitations. It's US made (!), and appears to be really well built. I use it
a fair bit.
However, the specs claim a current
I'm using two parallel 20ah 36v ebike batteries in a golf cart with good
success. I had been working with the mental model that all batteries in
parallel should be of equal capacity. On more careful consideration, I
now see no reason to have equal capacity batteries. That is, I might
