LiPo battery packs: finished packs, not single cells
Twenty-six lithium polymer pack models, from single-series packs to multi-series packs for higher voltage. Choose a pack when you need finished wiring and protection, not a bare cell.

A battery pack is more than cells taped together. The series count sets the nominal voltage — a 3-series pack is commonly 11.1 V — the parallel count sets capacity, and the protection circuit decides what happens on overcharge, over-discharge and short circuit. That is why a pack inquiry needs more information than a cell inquiry: the buyer must state the voltage, the capacity, the peak current, and what protection the application expects.
The pack range includes medical equipment packs, consumer electronics packs and IoT and portable instrument packs. One representative example is the 603048-3S pack for medical equipment, detailed on its own page with its own listing values. Other packs in the family differ in series count, capacity and terms, and this page does not carry any one pack's numbers across the family.
When you ask about a pack, name the application first. A medical device pack, a handheld instrument pack and a portable speaker pack may share a voltage but differ in protection, wiring and documentation needs. Certificates are available upon request for the exact model, and the certificate set should be confirmed for that model before samples are agreed.
How to choose in this family
Fix the shape first, then the voltage and series count, then the capacity. Check the exact model listing for its own minimum order, enquiry price range, lead time and certificate set — those values belong to that listing and do not transfer to other models. If no listed size fits your enclosure, the custom route covers custom dimensions and shapes; describe the enclosure rather than asking for a general price.

How to place an inquiry, step by step
- Send the device facts. Tell us the device type, the available space (length, width and maximum thickness), the nominal voltage you need, the capacity or runtime you target, and the peak current if your device has motors, radios or heaters.
- Name the model or the shape. If a page on this site matches, quote its model number and listing details. If nothing matches, say so and describe the shape — flat, round, curved or ultra-thin — so the conversation starts on the custom route.
- Confirm documents and terms in writing. Ask for the certificate set for that exact model, confirm the minimum order, the listed enquiry price range and the lead time for that listing, and confirm payment and warranty terms before you pay. Terms stated for one model listing do not transfer to another model.
- Agree the sample step. Confirm whether the next step is a listed sample, an engineering sample for a custom shape, or a small trial order, and what test you will run on arrival — fit in the enclosure, runtime, or peak-current behaviour.
Send all of this in one message through the contact page: device type, space, voltage, capacity, peak current, model number if you have one, and the documents you need. That is the whole inquiry — one message, no account, no extra step.
What to send us now
Send one message with your device type, the space the battery must fit, the voltage and capacity you need, the peak current if it matters, and the model number if a page on this site already matches. Add the documents you need — certificates available upon request — and whether you need a listed model or a custom shape. Use the contact page and address it to the sales team by first name as published there. A specific message like that is what turns a catalogue of hundreds of models into a short, answerable question.
