E-bike battery safety: certification, charging, storage

Lithium-ion batteries hold a lot of energy. Two things lower the risk: a certified electrical system, and charging and storing it the way fire services advise.

Certification: what to look for

UL 2849 is the "Standard for Safety for Electrical Systems for eBikes". In December 2022 the U.S. Consumer Product Safety Commission wrote to manufacturers asking them to meet it and to show compliance "through certification from an accredited testing laboratory".1

Every Velotric model we list states UL 2849 on its spec sheet, and lists its batteries under a second standard, UL 2271 (cells: UL 2580).4, 7, 8, 9, 10, 11, 12, 13, 14, 15 Velotric also rates its bikes IPX6 and its batteries IPX7 against water.5 A certification lowers risk; it doesn't remove it, so the habits below still apply.

Charging

  • Be there while it charges; don't charge while you sleep or when nobody's home.2
  • Use the charger that came with the bike or one the maker recommends.2, 3
  • Plug the charger directly into a wall outlet, not an extension cord.3
  • Not in the bedroom, not near exits (doors, windows, fire escapes), and not in direct sunlight.3
  • Charge on the floor and away from anything that can catch fire.3

Storage

  • Store and charge outside where possible, and away from extreme heat or cold.3
  • Replacement batteries: only the maker's compatible battery, or one tested and approved for your bike.2, 3
  • Watch for odors, a change in shape or color, leaking or odd noises. If you notice any, stop using it, move it away from anything that can burn if it's safe to do so, and call 911.3
  • Never put lithium batteries in the trash or regular recycling; use a battery drop-off.2

Removable battery? It lets you charge indoors while the bike stays in a shed or garage. The Nomad 2, Nomad 2X and Breeze 1 list removable batteries.10, 11, 15 Velotric's return policy lists "Batteries — non-returnable due to shipping regulations".6

In New York City, Velotric currently doesn't ship e-bikes to city addresses, citing city regulations.4
