I currently have a 48 volt 10ah stock LiMn battery(pedego). testing the volts it charges to 58.75 volts. Why does my current battery go well beyond 48 volts , is pedego peak charging them for more power. Question 1 is how low can I run down the voltage and not shorten the battery life too much . Question 2 when I purchase a new battery Will a 52 volt luna battery charge higher than 52 volts a 48 v luna higher than 48 ,

Assuming what you're measuring is accurate that probably is a 52V battery pack.
It must be because true 48V 13S would then have 4.5V per cell group which is on the verge of catching fire.

ok pedego claims its 48 volt 10 ah battery, but right on the charger (from them ) it states charging voltage 58.8volts at 2 amps per hour , my watt meter on both batteries I own confirms this. want to purchase another battery that costs less they want 900 , with more amp hours (luna triangle do I go with 24volt or 52volt x 24ah , and do the 52 volt batterys max out at 52 volts charge?Comment

A 52V battery is 52 volts 'nominal'. Since a typical cell that Luna uses is 4.2V fully charged, a 52V pack that has 14 cells in series could fully charge to 58.8V. However you don't normally want 100% charge. Here, this article explains it better than I could, https://www.electricbike.com/52v-battery-3077-fet/Comment
