Immediate Start & Pedal First
Cut off voltage 29V (+-1v).

This was originally for SLA, but I use as is for Lith-Po
Batteries40 Crystalyte, 36.00 Volt, Lithium-Polymer
Battery pack was expensive at $600, and was $400 more than SLA, but it is 1/3 the weight and size of SLAs. The most important attribute is the output stays almost constant until the end. Unlike SLAs that the power falls off in the first 5 minutes and degrades linear (almost) from there.
