Those who've followed us over the past 6 years will remember that at various times we've carried multitudes of batteries from many manufacturers in all different voltages, chemistries, and form factors. This has lead to a wealth of firsthand battery experience, sometimes rewarding but mostly filled with hair pulling frustration.

We've decided for this year to simplify things (cut our losses) and just carry 3 battery choices from eZee that have proven dependable so far. The 36V 9Ah LiFePO4 as a standard option, a 36V 14Ah Samnsung LiMn pack for extra range, and 48V 10Ah Samsung LiMn for extra speed. All of these batteries in the same compact eZee flat pack enclosure casing. It's a tight form factor that we like, and there are several rack mounting options to facility secure attachment to the bicycle.
