Quick Fit Check
The CNHL 3700mAh 11.1V 3S 40C LiPo Battery with XT60 Plug is a practical mid-capacity 3S battery for RC users who want more runtime than a small 2200mAh or 3300mAh pack, but still want to avoid the extra size and weight of larger 5000mAh batteries. With 3700mAh capacity, 11.1V 3S voltage, 40C discharge output, and an XT60 plug, this pack works well in selected RC boats, RC paragliders, paramotors, sport aircraft, and other 3S setups where balanced weight matters.
This battery is a strong choice when your model supports 3S LiPo power, has enough battery space for a 136 × 44 × 26mm pack, can handle an approximately 310g battery, and uses an XT60 connector or a properly rated adapter. Before buying, always check voltage, connector, battery bay size, wire clearance, and center of gravity.

Core Description
The CNHL 3700mAh 3S LiPo battery is built for RC users who want a useful runtime upgrade without jumping straight to a large and heavy 5000mAh pack. The 3700mAh capacity gives more usable time than smaller compact 3S batteries, while the 40C discharge rating keeps power delivery smooth and predictable for everyday RC use.
For many 3S platforms, this battery sits in a practical middle ground. It is large enough to improve runtime, but still compact enough for models where battery weight affects handling, launch feel, hull balance, flight trim, or center of gravity. That makes it a good choice for users who care about control as much as capacity.
The XT60 connector is another practical advantage. Many modern RC aircraft, boats, and custom 3S setups already use XT60, which keeps the installation simple. If your model uses EC3, IC3, TRX, T/Dean, or another connector type, use a properly rated adapter or connector change and confirm polarity before running.
3S LiPo Battery for RC Paragliders and Paramotors
The CNHL 3700mAh 11.1V 3S 40C LiPo Battery with XT60 Plug is a strong mid-capacity option for RC paraglider and paramotor pilots who want longer cruising time without making launches feel heavy or sluggish. Compared with smaller 3S packs, this 3700mAh battery gives more duration. Compared with larger 5000mAh packs, it can be easier to balance and more comfortable for canopy-wing models.
For RC paraglider and paramotor setups, battery selection is not only about capacity. Weight, CG position, launch behavior, motor load, and ESC cooling all matter. This 3700mAh 3S pack is a practical option when your setup needs a little more flight time while still keeping the aircraft responsive.
It is included in our dedicated 3S battery lineup for canopy-wing models here: 3S LiPo Batteries for RC Paragliders & Paramotors.
ProBoat Sonicwake 24 Battery Upgrade
This CNHL 3700mAh 3S pack is a strong pick for ProBoat Sonicwake 24 owners who want more time on the water without moving to an oversized battery. If your goal is a Sonicwake 24 battery with extra capacity, this is a practical step up from smaller 3S packs while still staying within a sensible upgrade range for a compact deep-V boat.
For the Sonicwake 24, battery choice affects more than runtime. A heavier pack can change hull balance, self-righting behavior, acceleration, and handling in chop. This 3700mAh 3S LiPo battery gives a useful runtime increase while keeping the setup more manageable than larger high-capacity packs.
Since the Sonicwake 24 runs an IC3 / EC3-style connector and this battery uses XT60, pair it with the XT60 to EC3 adapter for easier compatibility. For users searching for a 3S LiPo for Sonicwake 24, this setup keeps the wiring simple and the runtime longer.

FAQ
What is this 3700mAh 3S LiPo battery best used for?
It is best used in RC models that need a balanced 3S battery with more runtime than smaller packs but less weight than larger 5000mAh batteries, including Sonicwake 24 setups, RC paragliders, paramotors, sport aircraft, and selected RC boats.
Can this battery work in the ProBoat Sonicwake 24?
Yes, it can be used as a Sonicwake 24 battery upgrade when paired with a suitable XT60 to EC3 adapter. Always confirm tray fitment, wire clearance, hull balance, and secure mounting before running.
Is this battery direct plug-and-play for Sonicwake 24?
No. This battery uses an XT60 plug, while the Sonicwake 24 is commonly associated with IC3 / EC3-style connector setups. Use a properly rated XT60 to EC3 adapter or connector conversion before use.
Is 3700mAh better than 3300mAh?
It depends on the model. A 3700mAh battery usually gives more runtime than a 3300mAh pack, but it is also heavier. It is a good choice when you want a little more duration and your model can handle the extra weight.
Can this battery be used for RC paragliders and paramotors?
Yes, if the model is designed for 3S power and can balance properly with a 310g battery. Always check launch behavior, CG, motor load, and ESC temperature after changing battery size.
Is XT60 the same as EC3 or IC3?
No. XT60, EC3, and IC3 are different connector formats. EC3 and IC3 are often discussed together in RC battery searches, but this specific battery comes with an XT60 plug. Use the correct connector or a properly rated adapter for your model.
Notice
- Only use a compatible LiPo balance charger designed for 3S LiPo batteries.
- Stop charging immediately if any cell exceeds 4.2V.
- Check voltage, connector type, adapter rating, battery tray size, wire clearance, and model balance before purchase.
- Inspect the battery surface, connector, wires, balance lead, and cell voltage before first use.
- Do not use the battery if it becomes swollen, damaged, overheated, or physically deformed.
- For adapter use, confirm polarity and current rating before connecting to the ESC.
- For long-term storage, store the battery at proper storage voltage in a cool and dry place.
- If a new battery does not initially hold full performance, several normal balanced charge and discharge cycles may help stabilize the cells.
- Always follow standard LiPo safety procedures during charging, storage, transport, and use.
