Trojan doesn't publish AH @ 1-hr rate for their batteries, but US Battery does.
Their 8V 170AH cart battery has 105AH at the 1-hr rate.
If only 50% is usable, there is 52.5AH available.
The Li battery is 100AH @ 1-hr rate, but how much of that is usable?
I don't know much about LI battery packs, but from what I've read they aren't fully charged or fully discharged because overcharging and over-discharging kills them. Again, from what I've read, some people charge to 90% and discharge to 10% while others only charge to 80% and discharge to 20%, so the usable range is either 80% or 60%, so 60AH to 80AH is available.
On the other hand, the 1-hr rate for the lead-acid battery is an amp flow of 105A, which is a pretty high for the average amp flow while driving a cart, so their true AH capacity is likely to be in the neighborhood of 55AH, or more.
Looks like the 48V 100AH Li pack linked to will provide more driving distance than the T-875 pack without taking the lighter weight into consideration.

Question to those that know more about lithium battery packs.
Should the max battery amps slider in the XCT be set to the recommended max amp draw from the 100AH Li battery pack?
