Ebike Battery Prices

How to pick an ebike battery by price per watt-hour

Price per watt-hour is the honest way to compare ebike batteries because it divides out marketing. A watt-hour is one watt of power delivered for one hour, so a 48V 20Ah pack holds about 960Wh no matter what the listing calls it. Divide the price by the watt-hours and you get a number that lets a $150 no-name pack compete fairly with a $600 brand pack. This table keeps all 324 listings sorted by that number, and the leader currently sits at about $0.08/Wh.

What voltage do I need: 36V, 48V, or 52V?

Match your controller, not your wishes. Most stock commuter and folding bikes run 36V, most Rad Power and mid-tier bikes run 48V, and 52V packs suit performance builds whose controllers accept the higher full-charge voltage (58.8V). Putting a 52V pack on a 36V-only controller can damage it. The voltage filter above narrows the table to packs that match your system.

Which battery form factor fits my bike?

Form factor decides whether the pack physically mounts at all. Hailong and Shark packs slide into downtube mounts common on Rad Power-style frames. Silver Fish packs fit folding bikes like the Lectric XP. Triangle packs fill the frame cavity on DIY builds and swap into many full-suspension frames. Rear rack packs mount anywhere a rack bolts on. Use the form factor filter above, then confirm connector type with the seller before ordering.

How long should an ebike battery last?

Plan on 800 to 1,000 full charge cycles for a standard lithium-ion pack, which is roughly three to five years of daily riding before capacity drops to about 80 percent. LiFePO4 packs cost more per watt-hour but double that lifespan. Store the pack at room temperature, charge it indoors, and never charge below freezing, and any pack in this table will outlast its warranty.
