Buying Guide: Flywoo P30B 3000mAh Long-Range FPV Battery
The Flywoo Explorer Molicell P30B battery is designed for pilots who want longer cruising time, stable power delivery and an efficient alternative to a heavy 21700 battery pack. Its high-power 18650 cells make it a strong choice for long-range exploration and smooth cinematic flying.
Buy the 4S1P version for the Flywoo Explorer LR4 or another compatible 4S micro long-range drone. Choose the 6S1P version only when the motors, ESC, electronics and connector are fully compatible with 6S voltage.
MEPSKING Expert Review
In MEPSKING’s specification and application assessment, the main strength of the Flywoo P30B battery is its balance of weight, usable energy and current capability rather than maximum throttle punch.
The 4S version provides approximately 44.4Wh of listed nominal energy while weighing 196.5g. On an efficient four-inch platform, it provides a much larger cruising window than a small 750–900mAh LiHV battery. The trade-off is a heavier takeoff feel, slower braking and reduced agility.
Flywoo rates the pack for up to 35A peak output, while Molicel specifies a 30A continuous discharge rating for the P30B cell. This makes it more capable than many energy-focused 18650 packs, but it remains a Li-Ion cruising battery rather than a high-C racing LiPo.
Real-World Flight Experience
Compared with a small LiHV battery, the P30B pack makes an Explorer-style drone feel heavier during acceleration, turns and braking. In return, it provides a noticeably longer cruising window and more time to plan the return route.
The best results come from smooth mid-throttle cruising. Repeated full-throttle climbs and aggressive freestyle increase voltage sag and heat while reducing the endurance advantage. Flywoo states that a compatible Explorer LR4 can reach up to approximately 28 minutes under efficient cruising conditions, although wind, payload, propeller condition and flying speed can change the result substantially.
Pilots who want maximum agility or a sub-250g setup should consider a smaller LiHV battery. Pilots planning dedicated long-range missions should choose the P30B. Read the Flywoo Explorer LR4 long-range review for more information about battery and flight-time choices.
Flywoo P30B 4S vs 6S: Which Should You Buy?
| Specification | 4S1P 3000mAh | 6S1P 3000mAh |
|---|
| Listed Nominal Voltage | 14.8V | 22.2V |
| Maximum Charge Voltage | 16.8V | 25.2V |
| Approx. Listed Energy | 44.4Wh | 66.6Wh |
| Weight | 196.5g | 295.7g |
| Discharge Connector | Flywoo XT30UP | XT60 |
| Best Application | Explorer LR4 and efficient 4S micro long-range builds | Compatible 5–7-inch 6S long-range builds |
| Purchase Advice | Choose for an Explorer LR4 or confirmed 4S setup | Choose only when the complete power system supports 6S |
Do not select 6S simply because it has a higher voltage. A 6S battery can damage a 4S-only ESC, motor or power system. It also adds almost 100g compared with the 4S version.
Flywoo P30B vs iFlight Fullsend 6S 4000mAh
The fair comparison is between the Flywoo 6S 3000mAh version and the iFlight Fullsend 6S 4000mAh Li-Ion Battery. The Flywoo 4S pack belongs to a different voltage class and is not a direct replacement.
| Comparison | Flywoo P30B 6S 3000mAh | iFlight Fullsend 6S 4000mAh |
|---|
| Cell Format | Molicel P30B 18650 | EVE 40P / 40PL 21700 |
| Capacity | 3000mAh | 4000mAh |
| Nominal Energy | Approx. 66.6Wh | 88.8Wh |
| Weight | 295.7g | 430g |
| Connector | XT60 | XT60H |
| Main Advantage | 134.3g lighter for better handling and efficiency | 22.2Wh more energy for maximum cruising endurance |
| Purchase Advice | Choose when lower weight matters more than maximum capacity | Choose when a large 6–7-inch drone can carry 430g |
Choose the Flywoo 6S P30B when lower takeoff weight, easier handling and better energy-to-weight performance are the priorities. Choose the iFlight Fullsend when the aircraft can carry an additional 134.3g and maximum cruising endurance is more important.
Frame and Application Compatibility
Choose the 4S1P version: For a Flywoo Explorer LR4, another efficient 4S micro long-range drone or a build that requires the Flywoo XT30UP connector.
Choose the 6S1P version: For a confirmed 6S-compatible long-range or cinematic build with an XT60 connector and enough frame space for a 295.7g battery.
Choose a LiPo instead: When racing performance, repeated punch-outs, rapid recovery and aggressive freestyle response are more important than maximum cruising time.
Before ordering, verify the supported battery voltage, motor KV, ESC input range, connector, frame dimensions, center of gravity and expected cruising current. Browse more FPV batteries if your build requires a different voltage, weight or discharge capability.
Charging and Installation Notes
Use a balance charger that supports the selected cell count and Li-Ion chemistry. The P30B data sheet specifies a maximum charge voltage of 4.20V per cell, which equals 16.8V for 4S and 25.2V for 6S. A conservative routine charging current for this 3000mAh pack is 3A.
The ISDT 608AC balance charger supports both 4S and 6S charging, but the appropriate XT30 or XT60 charging cable may be required.
Secure the battery with a non-slip pad and battery strap, keep the balance lead away from the propellers and check individual cell voltages before every long-range flight. Never charge unattended, and stop using a pack that is damaged, badly unbalanced or unusually hot.
Do not use the cell manufacturer’s laboratory 2.5V cutoff as a normal landing target. Return with adequate battery reserve for headwind, route changes and unexpected current draw.
