High-discharge LiPo batteries: current when the device demands it
Twenty-five high-discharge models for devices with sharp current peaks — drones, power tools and equipment that draws far more at full load than at rest. The discharge rate belongs to the model listing, never to the family.

Discharge rate, written as a C-rate, says how fast a cell can safely deliver its charge relative to its capacity. A 20C cell rated at 300 mAh can in principle deliver a much higher peak current than a standard cell of the same capacity, which is why drones and power tools need this family. But the C-rate on a listing is that listing's claim for that model, measured for that design — it says nothing about a neighbouring model, even one with a similar number.
The representative model here is the 702030 high-discharge listing for drone applications: 3.7 V, 300 mAh, 7.0 x 20 x 32 mm, 20C, 500-times cycle life, with its own minimum order, enquiry price range and lead time. Other high-discharge listings in the family carry different rates, capacities and terms. A buyer choosing on C-rate alone, without checking capacity and size, will often pick a cell that fits electrically but not mechanically, or the reverse.
For a high-discharge inquiry, state the peak current and how long the peak lasts, not just the C-rate you think you need. A short burst and a sustained high draw are different requirements, and the right cell — or the right custom design — depends on which one your device actually presents.
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.
