Bikes: Too many to list, some I built myself including the frame. I "do" ~ Human-Only-Pedal-Powered-Cycles, Human-Electric-Hybrid-Cycles, Human-IC-Hybrid-Cycles, and one Human-IC-Electric-3way-Hybrid-Cycle

It should be noted that for best life Lithium batteries should only be discharged to about 80% depth of charge. Just like lead-acid should only be discharged 50%. Ni-Cd, NiMH, & NiFe are about the only ones that do well with 100% depth of dis-charge.

So in sizing with Lithium batteries one should size it to 125% of what you need to allow for only using 80% of the rated capacity.

Long story short a 48V 25Ah Lithium battery should give you the same amount of usable power as a 48V 40Ah lead-acid battery without over dis-charging the battery.
