Frequently Asked Questions
Q1: What is the range for a 48V 20Ah battery with a 1000W ebike motor?
Roughly 45–60 km in pure electric mode, and 70–100 km using pedal assist (PAS).
Q2: Why choose 21700 cells over 18650 cells?
21700 lithium ion battery cells offer higher energy density and capacity, requiring fewer parallel connections, which reduces weight and failure points.
Q3: What is the production lead time?
7–10 working days for custom battery samples; 20–25 working days for bulk OEM orders.
Q4: Do you provide matching chargers?
Yes, we supply 54.6V 2A/3A smart chargers with regional plugs (US, EU, UK, AU).
Q5: Are batteries certified for international shipping?
Yes, all shipments include UN38.3 test reports, MSDS documentation, and air/sea transport certificates.
