702030 high-discharge LiPo battery: 3.7 V, 300 mAh, 20C, for drones
One drone listing, stated exactly: 3.7 V, 300 mAh, 7.0 x 20 x 32 mm, 20C discharge rate, 500-times cycle life, with terms belonging to this listing alone.

This is the drone listing of the 702030, and its 20C figure is the reason the listing exists. A small drone needs a cell that can deliver sharp current peaks for take-off and manoeuvre without voltage sag, and a 300 mAh cell at 20C is designed for that burst behaviour. The same model number appears in other listings — including a 380 mAh listing with a different certificate set and terms — so a buyer must name the 300 mAh, 20C drone listing explicitly, or the conversation will drift to a different record with different properties.
At 7.0 x 20 x 32 mm, this is a compact cell for small drones and small portable devices. The size matters as much as the rate: a drone's battery bay is fixed, and a cell that delivers the right current but does not fit the bay is useless, just as a cell that fits but sags under load is useless. The listing's application list also names UPS, storage, solar, Bluetooth and wearable uses, which reflects the cell's general small-device suitability, but the listing title and the 20C rate are what mark it as a drone cell, and this page treats the drone use as the anchor.

Cycle life for this listing is stated as 500 times. That figure was measured under the listing's own test conditions, and a drone's real cycle count will depend on how hard it is flown — aggressive flying with deep discharges and high currents shortens life, while gentler use extends it. Buyers should read the 500-times figure as a comparison point between listings tested similarly, not as a promise of 500 flights for their aircraft.
Commercially, this listing states a 5-piece minimum order, an enquiry range of $0.96–1.50 and a 7-work-day lead time, all for this listing only. Those terms suit a sample-and-test purchase: order a small number, fly them in the real aircraft, and measure voltage sag under load and flight time before committing to volume. Confirm the price, lead time, payment and warranty terms in writing for this listing, and confirm the certificate set for your market, since this listing's own certificate field is not stated in the same detail as some other listings.
For a drone inquiry based on this cell, state the aircraft's voltage configuration, the battery bay dimensions against the 7.0 x 20 x 32 mm outline, the motor's peak draw, the target flight time and the weight budget. A single cell suits a small aircraft; a larger aircraft will need a series pack built from suitable cells, and that pack conversation starts from the same four facts.

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.
