🔋 Battery Storage
✅ Quick answer: store at ~40–60% charge, cool and dry.
If you are putting your ebike away for more than a week or two — over winter, during a move, or between seasons — a little storage prep dramatically extends the life of your pack.
Store at a partial charge (40–60%). This is the sweet spot. On the battery's LED indicator that is roughly 1 green light + 1 red light. Lithium cells age fastest when stored full and slowest at a middle charge, so a half-full pack loses far less capacity over a long rest than a full one. (For the technically inclined: 40–60% is about 3.6–3.8V per cell — roughly 48–50V on a 48V pack, or 51–53V on a 52V pack.)
- 40–60% (storage sweet spot) — ~Voltage: 3.6–3.8V per cell — ~48–50V on a 48V pack, ~51–53V on a 52V pack · LED: 1 green + 1 red
Store cool and dry. A cool indoor spot at room temperature or a little below is ideal — think a closet or basement shelf, not a hot garage or a freezing shed. Heat is the enemy of stored lithium cells. Keep the pack safe from falls and impacts.
Disconnect everything. Remove the battery from the bike, unplug it from the charger and the motor, and switch it off if it has a power switch.
Top it up every few months. Check the pack every 2–3 months during long storage and, if it has dropped, charge it back to that 40–60% level. Do not let a stored pack slowly self-drain down to empty — a pack that sits below its cutoff for a long time can be permanently damaged.
One thing to avoid: don't leave a battery sitting fully charged and unused for long stretches. Full + idle is the hardest combination on the cells. If you accidentally charged to 100% and then plans changed, either ride it down a bit or just be aware it is fine for a few days — the concern is weeks and months at a full charge.
Batteries are a final-sale item, so treating a stored pack well is real money saved.
