I bought my Fly 7 moped new in Dec 2021 and have since put 1800 miles on its 60 V 20 AH lead acid battery. I took these measurements today: Fully charged 66.5 V. @ full throttle it sags down to 55 V with a draw of around 34 amps per my clamp ammeter. Does that sound typical for a 3 year old lead acid battery with 1800 miles?
I am thinking of replacing it with a 60V 30 AH LiFePo4 battery from Amazon for $569 (+ tax). LiFePo4 is supposedly less prone to fire risk compared to Lithium Ion chemistry. BtrPower Amazon.com
Is BtrPower reputable? It has a BMS but no mention of balancing cells. Is $569 a reasonable price for such a battery? Are there other LiFePo4's you recommend?
Will I feel more pep from the LiFePo4 battery? What kind of sag should I see @ full throttle?
