Gens ace 850 mAh 4S Battery with XT30 Connector
The Gens ace 850mAh 4S battery is a compact LiPo battery for drones and other RC models with power systems compatible with a four-cell battery rated at 14.8 V. Its 850 mAh capacity, manufacturer-specified 80C discharge rating and XT30 connector make it a suitable choice for models that require a balance between battery weight, dimensions and current delivery. Weighing approximately 96 g, it is particularly suitable for applications where a higher-capacity battery pack would add too much weight or take up too much space.
4S LiPo Battery for Drones with Compatible Power Systems
The battery uses a 4S1P configuration: four lithium polymer cells connected in series provide a nominal voltage of 14.8 V. A fully charged 4S LiPo battery reaches 16.8 V, so the drone’s electronic speed controller, motor configuration and any other components powered directly by the battery must support this voltage.
When choosing the Gens ace 850mAh 4S battery, follow the drone manufacturer’s recommended battery voltage and capacity. An XT30 connector alone does not guarantee full compatibility: the model’s current requirements, battery dimensions and suitable weight must also be considered. A correctly selected battery matches the drone’s power system and helps maintain appropriate weight distribution.
850 mAh Capacity and 80C Discharge Rating
The 850 mAh capacity is suited to applications where a compact battery pack and low weight are priorities. Battery weight affects both a drone’s overall mass and its flight characteristics, so a higher-capacity battery is not always the best choice. This model’s approximate weight of 96 g makes it easy to account for the battery’s contribution to the total weight when building a drone or selecting a replacement battery.
The manufacturer-specified 80C discharge rating describes the battery’s current delivery capability relative to its capacity. This is relevant for drones whose motor loads change rapidly during flight, such as during acceleration or sharp manoeuvres. When assessing the suitability of the complete power system, the current limits of the connector, wiring and electronic speed controller must also be considered.
Actual flight time depends on the drone’s weight, motors, propellers, flying style and weather conditions. A specific flight time therefore cannot be determined from the 850 mAh capacity alone.
Compact Dimensions and XT30 Connection
According to the manufacturer, the battery pack measures approximately 60 × 31 × 30 mm. Its compact size allows it to be used in models with limited battery space, provided the drone’s design and mounting arrangement accommodate these dimensions. Before choosing the battery, measure the battery compartment or mounting area and allow sufficient room for the cables and connectors.
The battery features an XT30U-F power connector, part of the XT30 connector family. The drone must have a compatible mating connector. A JST-XHR-5P balance connector allows a suitable charger to monitor and balance the voltages of all four cells.
Charging and Everyday Use
Charging the Gens ace 850mAh 4S battery requires a LiPo-compatible charger that supports 4S battery packs and balance charging. Select the appropriate LiPo charging programme and four-cell setting on the charger. Follow the battery manufacturer’s instructions when setting the charging current: 80C is the discharge rating, not a recommended charging rate.
Balance charging helps keep the individual cell voltages consistent. If the battery will not be used for an extended period, a suitable charger’s storage mode can bring it to the appropriate storage voltage.
A Suitable Choice for a Compact 4S Drone
The Gens ace 850mAh 4S battery is suited to drone users looking for a lightweight LiPo battery pack with a nominal voltage of 14.8 V and an XT30 connector. Its key specifications include an 850 mAh capacity, an 80C discharge rating, an approximate weight of 96 g and dimensions of 60 × 31 × 30 mm. If these specifications meet the drone’s technical requirements, the battery is a suitable option for both a new build and a replacement for an existing battery.
