A custom 12V (or 12.8V nominal) 3.3Ah lithium PVC wrap battery is a lightweight, compact power pack typically built using LiFePO4 chemistry (such as 32700 or 26650 cells) wrapped in protective blue or black PVC film rather than a hard plastic or metal case.

A compact 12.8V 3.3Ah LiFePO4 pack in PVC wrap, sized for OEM device integration where internal volume is the binding constraint. It carries 42 Wh of usable energy and delivers 2A continuous, a 0.61C rating suited to mixed duty: sustained running with periodic higher demand.
Charging at 2A brings it to full in roughly 2.5 hours. The operating window is -20~50°C on discharge and 0~50°C on charge. The pack measures 118 x 76 x 30 mm and weighs 0.45 kg.
This is the entry point of our 12V range. The next step up is 10Ah, which is where most projects land once the duty cycle is modelled properly.
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.
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.
Why PVC wrap instead of a plastic case?
Wrap saves volume and weight and costs less at low volumes. A moulded case makes sense when you need ingress sealing or the volumes justify tooling.
Grade A 26650 cylindrical LFP 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. LiFePO4 warranty typically runs 3–5 years, set against the discharge duty of the application; high-rate cycling shortens it.
