Store your pack at about 40–60% charge somewhere cool and dry, top it up every few months, and never leave it full, empty, or hot — that's how you keep it healthy for years.
Store it at about 40–60% charge (~3.6–3.8V per cell, roughly 48–50V on a 48V pack or 51–53V on a 52V pack), somewhere cool and dry, and top it up every few months so it doesn't drift too low. Don't store it full, dead-empty, or hot — those are what age a pack fastest. Never charge below freezing.
Volts, amps, and capacity made simple: convert any pack to watt-hours (volts times Ah) and you can always tell which battery really holds more energy and range.
We ship every order rather than offering local pickup or will-call. Keeping the warehouse lean is part of how we hold prices down and pass the savings on to you.
We ship anywhere in the United States, with a couple of limits to know: no international orders, no PO boxes for kits or batteries, and batteries to the continental U.S. only.
Own a bike shop? Getting wholesale pricing is simple: submit the dealer request form on our wholesale page, and we typically approve accounts within about 24 hours.
Track your order anytime: once it ships you'll get an automated tracking email, and you can view full order history by logging in or using our no-account tracking page.
