Product overview
The WES 16000mAh 6S1P LiHV LiPo Battery Pack from Huizhou WES New Energy is a flight battery, not an aircraft or airframe kit. It is built for heavy-lift multirotors used in crop spraying, surveying, and inspection. Six lithium high-voltage polymer cells are wired in series with no parallel strings, charging to 4.35V per cell. That gives a 23.1V nominal rating, a 25.8V maximum, and 16000mAh of capacity, or 369.6Wh. Because the capacity sits in one pack, there's no need to pair two smaller batteries in parallel, which simplifies wiring and fleet charging.
Physically, the pack measures 58 × 71 × 200 mm and weighs 1600g, give or take 20g. The manufacturer positions it for drones carrying 8–12kg payloads. Main power runs through an XT90 connector, and a JST-XH lead handles balancing and telemetry. The rated continuous discharge is 30C (480A), with a 40C pulse rating (640A) allowed for up to 10 seconds. That headroom is meant to cover combined loads such as gimbals, RTK receivers, and spray pumps. Charging current tops out at 80A, but the recommended rate is 5C.
There are some practical limits to plan around. Reaching full capacity requires a charger set to LiHV mode. In standard LiPo mode, which stops at 4.2V per cell, the pack holds roughly 7% less charge and flight time drops. The pack can also run on systems designed for 22.2V 6S batteries, but only if the ESCs accept a maximum input of 25.2V–25.8V. Under lab conditions (25°C, 300A constant load, 80% depth of discharge), the rated cycle life is at least 400 cycles with less than 10% capacity loss. For real agricultural and survey work, the manufacturer cites 250–350+ flights before noticeable degradation.
