Custom 11.1V 2.6AH 18650 PVC Wrap Battery Pack

A compact 11.1V 2.6Ah lithium-ion pack in PVC wrap, sized for OEM device integration where internal volume is the binding constraint. It carries 29 Wh of usable energy and delivers 1.3A (Peak 5A) continuous, a 0.5C rating. This is a steady-load design rather than a high-rate traction pack.

Charging at 1.3A 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 57 x 70 x 19 mm and weighs 0.18 kg.

Where it sits in the range

This is the entry point of our 11.1V range. The next step up is 5Ah, which is where most projects land once the duty cycle is modelled properly.

What we customise

Almost everything is bespoke on a wrap pack: cell arrangement, connector, gauge and length, NTC placement, printing, protection thresholds. Most builds this size use a protection board; Bluetooth, CAN or RS485 are available where the device needs them.

Common questions

Can you match the footprint of our existing pack?
Usually. Send dimensions, connector and the device’s current profile and we confirm whether the cells fit the envelope before quoting.

How long does a design revision add?
Each revision restarts the 20–25 working day sample clock. Locking the envelope and current profile early is the biggest time saver.

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.
