The longevity of ebike batteries is a BIG unknown here.
One thing to watch out for is that (according to what I read on Endless
Sphere) some of the really cheap Chinese bike batteries are made with
recycled (used) laptop cells.
I don't know how

You're comparing apples and oranges.
- six T105s would be about $900.
- 12 TS-LPF100s: about $1500 + $300 BMS
- five 20ah ebike batteries @ $285. Total: $1425.
- Experience... indicates two 20ah ebike batteries can do ($570.)
Then also instead of six Trojans, 3 deep cycle 12v Lead batteries

Thanks! Bottom line, take away: 50-90 ah on a fresh lead pack.
It's not quite that bad. The Peukert effect does not change the ACTUAL
capacity; it only describes the APPARENT capacity due to high
currents. If you have a

Just checked Ping batteries, with an established good reputation:

Somewhat against my will, I just did some lead battery shopping. T105s
are about $150. The minutes at 75 amps rating seems most appropriate.
That would be just under 100 ah. From what you say, it appears those are
usable amphours. SAMs batteries, with presumably less
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?
The apples were 100 Ah comparisons. Then you changed to 40 Ah oranges,
without going back and putting the apples on the same

So the T105 is $150/(6v x 75a x 1.75hr) = $0.19/wh.
The Sam's Club is $80/(6v x 75a x 1.75hr) = $0.10/wh.
I didn't check SAMs' battery claims. I had assumed less capacity than
T105s.
I'm not sure what your all or nothing replacement means. You
