Rechargeable Li-ion battery packs: the second chemistry on this site
Fifty-seven rechargeable Li-ion pack models for equipment, devices and instruments. The page is deliberately titled with the rechargeable variant, keeping the generic pack terms for their existing use elsewhere.

Li-ion packs differ from LiPo packs mainly in cell format: cylindrical or prismatic hard-case cells rather than pouch cells. That changes the mechanical design — a Li-ion pack is often built around standard cell sizes — and it changes what custom means, because the pack is assembled from cells rather than shaped as a pouch. For a buyer, the practical difference is the enclosure: a Li-ion pack suits a device designed around rigid cells, while a pouch suits a device designed around a flat or curved cavity.
The range covers packs for portable devices, power tools, consumer electronics and equipment, with capacities and voltages varying widely across listings. As with every family on this site, the certificate set, minimum order, enquiry price range and lead time belong to the individual listing. Some listings carry extensive certificate combinations; others carry fewer. Compare listings, and ask for the certificate set for the exact model you intend to buy.
If you are choosing between a Li-ion pack and a LiPo pack for the same device, the deciding facts are usually the cavity shape, the voltage you need, and the peak current. The comparison guide on this site explains the chemistry trade-offs in general terms; the model listings decide the specific case.
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.
