E-bike battery replacement: get the maker's official pack

Your range has fallen off a cliff, or the battery just won't hold a charge, and a lookalike pack on a marketplace costs half the maker's price. This page is about why that's the wrong place to save money, and where the right pack comes from. It isn't about rebuilding or re-celling a pack: don't open it, and don't let anyone else do it for you.

Why the maker's pack, not a lookalike

• CPSC says so. Its micromobility page says to use only a replacement or secondary pack "tested and approved to work safely with your device" and confirmed suitable by the device manufacturer. It also says never to use a device with a battery pack modified or reworked by unqualified people, or built with repurposed or used cells.
• UL 2849 covers the system, not any pack that happens to plug in. The standard, per the Standards Council of Canada's listing, covers the e-bike's electrical system: drive unit, battery, battery management system, wiring and power inlet, with off-board chargers in scope. A third-party pack isn't automatically part of the system the bike was certified as. See our UL 2849 guide.
• The makers say the same. Lectric's XP4 manual says to buy a replacement battery pack from Lectric. Bosch's battery guide says other makers' replacement batteries are fine "only if it is ensured that these are compatible", and that it generally recommends original Bosch parts, which it says are always compatible and matched as a complete system. Ride1Up's pages say its packs only work with the named bikes, and that batteries are not returnable, so verify yours before ordering.
• Warranty. Velotric's warranty page says a battery bought separately is covered as an accessory for one year from its own purchase date, shorter than the battery that came with the bike.

Where each maker sells replacements

Prices below were shown on each maker's own page on 24 October 2026. They change, and some pages don't show a price until you pick your bike. Check before you order.

Details worth knowing:

• Aventon says its extra batteries need a battery cover, sold separately, and that the Pace 500.2 pack comes with a terminal conversion kit that must be used before installing. Its page says to submit a ticket for help.
• Lectric lists standard and long-range packs for some bikes at different prices. Use the compatibility line on each listing, and ask Lectric if you're unsure.
• Ride1Up says its Vorsa pack is certified to UL 2271 through TUV and doesn't include the cover, housing, charger or extra keys. We didn't find an official listing for every Ride1Up model, so call 1-877-RIDE1UP if yours isn't listed.
• Velotric: we didn't find a page for one specific pack per model. Call +1 888-559-3099 or email help@velotricbike.com (from its warranty page) and ask which pack matches your bike.
• Bosch: Bosch makes frame, rack and integrated packs, so the pack has to match your bike's mount. A dealer can match it.

If your battery is still under warranty, ask the maker first: Aventon's warranty is two years or 300 cycles and Velotric's battery warranty is two years or 300 cycles (details in how long e-bike batteries last).

Recycling the old battery

The Battery Network (the new name of Call2Recycle) runs an e-bike battery program with drop-off sites. Its page says to find a collection site that accepts your brand's batteries, because only brands that have joined the program are accepted. Enter your ZIP at batterynetwork.org/locator or call 1-877-2-RECYCLE. The locator page says some sites accept e-bike batteries, so check a location's details before you go.

For anything else, EPA says lithium-ion batteries should be taken to separate recycling or household hazardous waste collection points, not household garbage or recycling bins, and suggests contacting your local solid waste or household hazardous waste program. CPSC says the same, and that if your battery is covered by a recall or warning, you follow the disposal instructions in that notice.

FAQ

Can I use a cheaper third-party e-bike battery? CPSC says only to use a replacement pack that has been confirmed suitable by the device's maker. Bosch says other makers' batteries only if it's ensured they're compatible. We don't recommend packs the maker hasn't approved.

Are e-bike batteries interchangeable between brands? Not by default. Makers list packs by bike model. Ride1Up's pages say a pack works only with the named bikes, and Lectric lists packs by compatible model.

Can I just replace the cells in my battery? No. Bosch says not to repair or refresh worn batteries, and CPSC warns against packs modified or reworked by unqualified people or built with used cells. Ask the maker for a replacement pack.

Is the e-bike battery removable? That depends on the bike. Check your manual or the maker's spec page.

How do I get rid of my old e-bike battery? Use The Battery Network locator, or a household hazardous-waste site. Don't put it in the trash or curbside recycling.
