High Energy Density Series

Energy density is the number that decides how long a surveying, agricultural or delivery drone stays airborne. What most buyers miss: the same Wh/kg number can behave differently under load. Discharge rate, temperature and cycle depth all shift real-world endurance.

Our high energy density series spans 270 to 350 Wh/kg across configurable models. A 270 Wh/kg pack gives balanced endurance and cost per cycle. A 350 Wh/kg pack pushes endurance to the limit, which matters when payload margins are tight on mapping and delivery platforms.

Ask your supplier three questions: What Wh/kg does the pack actually deliver at your continuous discharge rate? What voltage sag appears at 10–20°C? And what is the cycle-life rating at 80% depth of discharge? The answers separate a catalog spec from a mission-ready pack.

Most commercial drone batteries on the market pass through a trader before they reach you. That trader adds a margin and, more importantly, a layer of distance between your spec sheet and the production line. When you buy direct from a drone battery manufacturer in China, the margin disappears and the distance closes.

Shengya Electronics is a drone battery supplier, not a broker. Our factory in Taixing, Jiangsu handles cell sourcing, pack assembly, BMS integration and testing under one roof. That single control point is what makes factory-direct pricing possible: bulk orders skip the middleman, and the price you approve at the sample stage is the price that ships with your batch.

Three things matter to any wholesale drone battery buyer: unit price at volume, consistency across batches, and lead time you can plan around. A direct supplier answers all three with the same production record — not a catalog page.
