Battery & Charging questions, answered

Can I fit a bigger battery?
Only one built for your bike. Voltage, connector, BMS and the frame mount all have to match, and a replacement pack must meet or exceed the stock capacity. Do not improvise a pack from another brand.
How should I store the bike over winter?
Charge the pack to roughly half, store it indoors at room temperature, and check it every few weeks, topping back up to half if it drifts down. Storing full or storing flat both cost you capacity permanently.
Can I return a battery?
No. Lithium batteries and packs cannot be returned, for shipping safety reasons — that is in our refund policy and it is a carrier rule, not a preference. If a pack arrives damaged or defective, send photos within 7 days and we will handle the replacement.
Is a fast charger bad for the pack?
It costs some cycle life, yes. The trade is convenience against longevity. If the bike is charging overnight anyway, use the slower charger and keep the fast one for the days you need a second ride.

About Battery & Charging

The pack is the most expensive part on the bike and the easiest one to shorten by accident. Chargers here are chosen for what they do to the cells, not just how fast they go: constant current to 80%, a taper above it, and a hard shutoff at 100% so a pack never sits at full voltage on a charger overnight.

Fast charging done properly. A 12A smart charger takes a Surron Light Bee X from empty to 80% in about 74 minutes and full in just over two hours, against five-plus hours on the stock brick. Auto voltage detect reads the pack before any current flows, so one unit covers a 60V Surron or Talaria and a 72V E-Ride Pro, and it ships with the GX16, XT90 and DC8.0 leads to match.

Read battery care that adds hundreds of cycles and the winter storage guide. Lithium ships ground only, to a street address.

Look after the expensive part.
