CNHL 3700mAh 14.8V 4S 40C Lipo Battery with XT60 Plug

Compatible RC Models & Use Scenarios

The CNHL 3700mAh 14.8V 4S 40C LiPo Battery with XT60 Plug is built for pilots who want a little more endurance and headroom without jumping to oversized packs. Compared to shorter 4S options, the added capacity provides longer flight times while still maintaining stable and predictable power delivery.

This pack is commonly used in mid-size RC airplanes where space allows for a slightly longer battery footprint. Models such as the E-flite Habu SS, Turbo Timber SWS, and Ultra Stick benefit from the balance between punch and efficiency that a 3700mAh 4S setup offers. The 40C discharge rating delivers confident throttle response without feeling overly aggressive, making it suitable for sport flying, scale aerobatics, and fast cruising.

Because of its length and weight, this battery works best in aircraft with a bit more room in the battery bay, where pilots can fine-tune center of gravity without pushing components to their limits. When installed cleanly and secured properly, it offers a very repeatable setup that many pilots appreciate for consistent flight behavior.

Eflite Gee Bee R2 1.0m 4S Lipo Battery Considerations

For aircraft like the Eflite Gee Bee R2 1.0m, battery selection is often less about maximum discharge rating and more about size, weight, and repeatable center of gravity. The compact fuselage and narrow CG window mean pilots tend to choose packs that can be installed consistently without forcing placement.

While shorter 4S packs are often preferred for fine CG tuning, a 3700mAh option can still work for pilots who want slightly longer flight times and have enough room to balance the aircraft properly. As with any Gee Bee setup, careful positioning and clean wiring make a noticeable difference in landing behavior and overall feel.

General Usage Notes

• Always confirm both voltage and connector compatibility before installation.
• Stop charging immediately if any cell reaches 4.2V; normal operating range is 3.7V–4.2V per cell.
• Inspect the battery for physical damage and verify cell voltage before first use.
• If a new battery does not hold charge consistently, perform several balance charge and discharge cycles before regular use.
