Quick Fit Check
The CNHL 3300mAh 14.8V 4S 30C LiPo Battery with XT60 Plug is a standard-length 4S battery for RC airplanes, twin-engine aircraft, sport models, STOL platforms and other installations designed around the 3200–3300mAh battery class.
Its 136mm-long case and approximately 361g weight make it different from a lightweight shorty battery. It is best suited to models with a conventional elongated battery compartment and enough center-of-gravity allowance for the installed mass.

Standard-Length 3300mAh 4S Battery for RC Airplanes
The CNHL 3300mAh 4S 30C LiPo Battery provides slightly more capacity than the commonly recommended 3200mAh battery class while remaining within the same general application range.
Its 136 × 44 × 30mm layout follows a conventional long aircraft-battery shape. This format is useful in models with elongated battery trays, where the pack can be supported along its full length and positioned consistently for repeatable center of gravity.
The approximately 361g weight makes this battery better suited to medium-size aircraft than lightweight foam models designed around 2200mAh packs. It can also provide useful forward ballast in models that naturally require a heavier battery near the nose.
Why Choose This Battery?
-
3300mAh capacity: Provides a small capacity increase over a 3200mAh pack while remaining within the same practical battery class.
-
Conventional 136mm format: Fits aircraft designed around a long, narrow 4S battery rather than a shorty layout.
-
Stable battery placement: The elongated case can be supported securely across a conventional battery tray.
-
Standard 4S voltage: Charges to 16.8V and does not require LiHV-compatible electronics.
-
30C output: Suitable for sensibly matched sport, STOL, twin-engine and recreational EDF power systems.
-
XT60 connector: Connects directly to corresponding XT60-equipped models without an adapter.
A Near-Stock 4S Battery for the Dynam E-2C Hawkeye
The CNHL 3300mAh 14.8V 4S 30C LiPo Battery with XT60 Plug is a practical near-stock-capacity option for the Dynam E-2C Hawkeye 1500mm twin-engine RC plane.
Its 3300mAh capacity is only slightly higher than the aircraft’s 3200mAh battery class, allowing pilots to remain close to the intended setup while gaining a small amount of additional capacity. The XT60 plug connects directly to the stock power connection.
The 30C rating is appropriate for the Hawkeye’s standard twin-motor power system, while the 136mm case provides a conventional elongated installation inside the top-loading battery compartment.

Compatible RC Aircraft and Applications
Twin-Engine RC Airplanes
The combination of 3300mAh capacity and a conventional long case is well suited to compatible twin-engine aircraft that require a stable 4S power source and have enough space for the 136mm battery length.
STOL and Bush Aircraft
Compatible STOL and utility aircraft can use the battery for mixed-throttle flying, repeated takeoffs and landings, and longer recreational sessions. Confirm that the approximately 361g weight does not move the center of gravity beyond the approved range.
Sport and Aerobatic Aircraft
The 30C discharge rating is suitable for sport models using a correctly matched motor and propeller system. The long case can provide repeatable positioning in aircraft where the battery tray is designed around a conventional stick-style pack.
Eflite Habu SS
The battery may suit compatible Eflite Habu SS configurations when the battery compartment accepts the 136 × 44 × 30mm case and approximately 361g weight. Confirm the exact model version, ESC voltage, center of gravity and connector before use.
Eflite Turbo Timber
For compatible Turbo Timber versions designed for 4S operation, the 3300mAh capacity can support STOL flying, general sport use and repeated touch-and-go practice. Check battery weight and center of gravity carefully because individual Timber versions have different battery and connector requirements.
Eflite Ultra Stick
The 3300mAh 4S battery can be considered for compatible Ultra Stick setups that accept its dimensions and weight. Its conventional long format can suit elongated battery trays, while the 30C rating supports normal sport and aerobatic flying in a correctly matched power system.
RC Boats and Custom 4S Projects
The battery may also be used in compatible RC boats and custom 4S vehicles where the battery tray, ventilation, connector and current demand match. It is a softcase aircraft-style pack and should be protected from impact, water and sharp mounting surfaces.

FAQ
Does this battery fit the Dynam E-2C Hawkeye?
Yes. The 3300mAh capacity remains close to the Hawkeye’s intended 3200mAh battery class, and the XT60 plug matches the stock power connection. Secure the battery and confirm the recommended center of gravity before flight.
Is 30C enough for a twin-engine RC plane?
It can be sufficient for a correctly matched twin-motor aircraft such as the standard Dynam E-2C setup. Confirm suitability through actual current draw, battery temperature and voltage performance.
Can this battery be used with an Eflite aircraft?
Yes. Many Eflite aircraft in this battery-capacity class use an IC3 power connector, so an XT60-to-EC3 adapter is required. EC3 and IC3 are physically compatible at the main power interface, allowing the battery to supply normal power through the aircraft’s IC3 connection. This setup does not provide Spektrum Smart battery data.
Should this battery always be charged at 5C?
No. The 5C specification is the maximum charge rate, not the required routine rate. A lower balanced charge rate generally creates less heat and places less stress on the cells.
Notice
- This is a standard 4S LiPo battery with a maximum charge voltage of 4.20V per cell.
- Use a compatible LiPo balance charger and select the correct four-cell setting.
- Confirm the 136 × 44 × 30mm dimensions, approximately 361g weight, XT60 connector and center of gravity before use.
- Secure the battery firmly and keep the main and balance wires away from motors, retracts, gears and other moving parts.
- Never charge unattended, and do not use a swollen, damaged or overheated battery.
- Allow the battery to cool before recharging and use storage mode when it will not be used for an extended period.
CNHL LiPo batteries come with a 90-day warranty from the date of purchase, unless otherwise stated in the product listing.
This warranty covers original defects in materials and workmanship. It does not cover normal wear and tear, puffing, swelling, over-disacharge, over-charge, improper storage, crash or water damage, connector changes, or any damage resulting from misuse or mishandling.
If you find that a battery purchased from us is defective within the 90-day warranty period, please get in touch with us to arrange a return for inspection. Based on our evaluation, we will usually repair, replace, or offer an appropriate solution at no additional charge.
