Custom 36V 20Ah Ebike Lithium Ion 18650 Battery Pack

A 36V 20Ah lithium-ion pack for electric two-wheelers, where pack volume and mass set the vehicle’s range and handling. It carries 720 Wh of usable energy and delivers 30A continuous — a full 1.5C draw, with headroom for the surge loads motive duty demands.

Charging at 10A brings it to full in roughly 2.5 hours. The operating window is -20~60°C on discharge and 0~45°C on charge. The pack measures 365 x 110 x 90 mm and weighs 5 kg.

Where it sits in the range

This is the entry point of our 36V range. The next step up is 30Ah, which is where most projects land once the duty cycle is modelled properly.

What we customise

Cell format, pack geometry, connector, wire gauge and BMS thresholds are set per vehicle. Communication over CAN or RS485 is available where the vehicle needs dashboard integration, with Bluetooth for rider-facing state of charge.

Common questions

Can the pack be removable for charging indoors?
Yes. Removable designs need a different connector and latch approach; tell us at quotation stage.

What certification do we need for our market?
Varies by market. Every pack ships with UN38.3 and MSDS; tell us the destination and we will discuss what else applies.

Cells, compliance and lead time

Grade A 18650 cylindrical ternary cells, generally specified with UL recognition at cell level. Every pack ships with a UN38.3 test summary and MSDS prepared for air, sea and road transport. Assembly and testing take around 7 working days. Cell supply is what sets the overall schedule: when the cells your design needs are in stock, samples ship in 12–15 working days; when they have to be sourced, allow 20–25. Tell us your target date early and we will confirm cell availability before you commit to it. Production runs 30–35 working days. There is no minimum order quantity — this is a custom design business and we quote single units, with pricing improving noticeably from 100 packs upward. Ternary lithium warranty typically runs 2 years.
