High Voltage Series (4.35V)

A 4.35V charge profile lifts energy density roughly 10–15% over standard 4.2V chemistry on the same weight. For weight- or volume-sensitive platforms — compact UAVs, racing drones, wearable devices — that gain is real.

The trade-off is cycle life and charger discipline. A 4.35V pack needs a charger and BMS that stop at the right voltage; overcharging shortens life fast. If your fleet already runs 4.2V chargers, standardizing on 4.35V means new chargers or strict voltage limits.

We spec 4.35V packs with the matching BMS and charging profile so the higher density actually survives field use. Tell us your platform's charge limit and we will confirm the right configuration before you commit.

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.
