Freewing BAC Lightning 64mm EDF Battery Guide – 4S LiPo Battery Options

LiPo Batteries for Freewing BAC Lightning 64mm EDF (4S 14.8V)

The Freewing BAC Lightning 64mm EDF is a light, compact, toss-and-go jet built around a 4S power system. With its hand-launch friendly fuselage and strong 4S thrust, choosing the right battery capacity and weight makes a noticeable difference in how confidently the Lightning leaves your hand and how long it stays in the air. This page collects the most suitable 4S LiPo options for balanced performance, smooth handling, and reliable hand launches.

For the Lightning’s compact airframe, the ideal battery range begins with 4S 1800–2200mAh packs, which match the aircraft’s recommended weight and deliver strong acceleration with minimal launch effort. Pilots who prefer slightly longer flight times can explore higher-capacity packs, provided takeoff method and airfield conditions allow for the extra weight.

Hand launching benefits from a lighter pack, typically 2200mAh or below, helping the jet climb immediately after release. When using the optional fixed landing gear for rolling takeoffs, the aircraft can tolerate a higher all-up weight, making 2500–3000mAh packs a practical step-up option.

The Lightning’s battery bay supports XT60-connector batteries as standard. Larger 4S packs equipped with XT90 connectors may also be used when paired with a suitable XT90-to-XT60 adapter. Ensure that wire routing remains clear of the hatch and that the battery sits securely against the tray without compressing foam surfaces.

As with any EDF jet, using high-quality LiPo batteries with strong continuous discharge ratings helps maintain punch during vertical climbs and avoids voltage sag in demanding maneuvers. Allow packs to cool before recharging, and avoid flying below safe voltage levels to maximize cycle life.

Best 4S LiPo Battery Options for the Freewing BAC Lightning 64mm EDF

The Freewing BAC Lightning 64mm is designed around a 4S power system using packs in the 1800–2200mAh class. These batteries keep the jet light enough for confident hand launches yet still provide strong vertical climb and the distinctive jet-like sound of a 12-blade EDF. For pilots who prefer extended flight times or rolling takeoffs, larger 4S packs can be used as long as the aircraft’s center of gravity remains stable.

How to Select Capacity and C Rating for a 64mm EDF Jet

EDF jets pull high instantaneous current during acceleration, vertical climbs, and full-throttle passes. A higher C rating reduces voltage sag and helps maintain thrust throughout the flight. Capacity determines the balance between weight and duration: smaller packs improve launch characteristics and agility, while larger packs increase flight time at the cost of added mass.

Hand Launch vs. Rolling Takeoff: Why Battery Weight Matters

The Lightning hand launches exceptionally well when using 2200mAh-class packs, allowing the jet to leave the pilot’s hand cleanly and climb without hesitation. Heavier packs, such as 2500–3000mAh, are best paired with rolling takeoffs using the optional landing gear. These combinations offer noticeably longer flight times and increased energy retention in windy conditions.

Understanding Connectors, Adapters, and Fitment

Most 4S packs suited for this model use XT60 connectors, which align with the factory ESC. Larger 4S performance packs equipped with XT90 connectors may also be used when paired with a reliable adapter. It is important to ensure that wire routing does not interfere with the spring-loaded battery hatch and that the pack fits firmly without compressing the surrounding foam structure.

Community Impressions of the Freewing BAC Lightning 64mm

The Lightning has generated strong enthusiasm among EDF pilots, many praising its unique silhouette, stable flight characteristics, and the novelty of seeing such an iconic British interceptor represented in foam. Numerous pilots have already placed orders, with some expressing intent to purchase more than one. Others are calling for larger 70mm, 80mm, and 90mm versions, reinforcing just how well this aircraft has been received by the community.
