How to Choose the Right RC LiPo Battery Strap
A reliable battery mounting setup starts with choosing a strap that matches the battery's physical dimensions and the mounting arrangement. Whether you're securing a compact FPV drone battery or a large LiPo pack for an RC airplane, car, or other battery-powered model, the strap needs enough length to wrap around the pack while leaving sufficient hook-and-loop overlap.
CNHL offers three practical strap lengths: 250mm, 300mm, and 500mm. The 250mm version uses textured woven fabric and a metal D-ring buckle, while the longer 300mm and 500mm versions feature a smooth PU surface and reinforced plastic rectangular buckle.
Each version is available as a 3-pack, making it convenient to equip multiple RC models or keep spare straps for battery changes.

250mm Woven FPV Battery Straps: Compact and Easy to Adjust
The 250 × 16mm FPV battery strap is designed for compact battery mounting setups. Its textured woven fabric construction differs from the smooth PU surface of the longer CNHL straps, and its metal D-ring provides a convenient return point for tightening.
For everyday FPV applications, the 250mm length is particularly suitable for LiPo batteries around 2200mAh and below, where the battery dimensions and frame mounting path allow sufficient fastening overlap.
Both available logo versions share the same dimensions, material construction, and fastening design:
- CNHL Logo: Black woven strap with stitched CNHL branding.
- Speedy Pizza Drones Logo: Same 250 × 16mm construction with distinctive Speedy Pizza Drones branding.
Choose the logo you prefer without needing to compromise on strap dimensions or buckle design.
Actual FPV Fit: 6S 1500mAh and 2200mAh
The CNHL 250mm woven strap has been physically fitted around CNHL 1500mAh 6S and 2200mAh 6S FPV LiPo batteries. The Speedy Pizza Drones version has also been demonstrated around the CNHL 2200mAh 6S pack.
These examples show the practical size range of the shorter woven strap. However, a battery that can be wrapped on its own may require additional strap length when installed on a frame, especially if the mounting slots require a longer routing path.

300mm PU LiPo Battery Straps: Versatile Fit for FPV and RC Batteries
The 300 × 20mm CNHL PU battery strap is the versatile option for users who need more wrapping length than a compact FPV strap provides, without moving to an extra-long 500mm design.
Its smooth polyurethane front features CNHL branding and stitched edges. The reverse uses separate hook and loop sections, while the black reinforced plastic rectangular buckle allows the strap to be tightened and fastened.
From 1300mAh 6S FPV to 9500mAh 6S
Actual fitting examples demonstrate the versatility of this length. The 300mm strap has been used with both a compact CNHL 1300mAh 6S FPV battery and a considerably larger CNHL 9500mAh 6S LiPo battery.
That range makes the 300mm version a practical starting point for users who own different RC battery sizes. However, always verify the battery dimensions, the mounting arrangement, and the available fastening overlap rather than treating 9500mAh as a universal size limit.

500mm PU Battery Straps: Extra Length for Large LiPo Packs
Large-capacity RC batteries require considerably more strap length, especially when the pack is wide, thick, or installed in a mounting setup with a long wrap path. The 500 × 20mm CNHL PU battery strap offers an extra-long alternative for these applications.
It shares the smooth PU front, reinforced plastic buckle, and two-section hook-and-loop fastening of the 300mm version, with an additional 200mm of length.
Actual Fit Example: CNHL 32000mAh 6S LiPo
The 500mm strap has been physically fitted around a CNHL 32000mAh 6S LiPo battery. This makes it a useful option to consider when securing batteries of approximately 10000mAh or larger, subject to the battery's actual dimensions and installation requirements.
Because very large LiPo batteries can be heavy, the ability to wrap a strap around a pack should not be interpreted as a tested load rating. Select the full retention system according to the model's mounting requirements, and use additional restraints when necessary.

PU vs Woven Fabric: Understanding the Strap Designs
Not all LiPo battery straps have the same surface construction. CNHL's 250mm woven straps and 300mm/500mm PU straps use different materials and buckle types, making it easy to choose according to the intended installation.
Woven Fabric FPV Straps
The 250mm straps have a textured woven fabric body, a stitched logo patch, and a metal D-ring buckle. Their 16mm width and relatively short length make them well suited to compact FPV battery mounting arrangements.
Smooth PU Battery Straps
The 300mm and 500mm straps feature a smooth polyurethane front with stitched edges, a black reinforced plastic rectangular buckle, and hook-and-loop sections on the reverse. Their 20mm width and longer length make them suitable for a broader selection of RC battery dimensions.
Neither strap type should be selected solely because of its surface material or buckle appearance. Correct length, secure fastening overlap, and compatibility with the mounting arrangement are more important for a reliable installation.
How to Measure for a LiPo Battery Strap
A battery's mAh rating describes its electrical capacity, not its external dimensions. Two 6S batteries of similar capacity may have different widths, thicknesses, and case designs. That is why checking the required strap length is more reliable than using capacity alone.
Step 1: Measure the Battery Cross-Section
When the strap wraps around the battery's width and height, estimate the perimeter using:
Battery Wrap Perimeter ≈ 2 × (Battery Width + Battery Height)
For example, a battery measuring 45mm wide and 35mm high has a cross-section perimeter of approximately 160mm.
Step 2: Allow for the Mounting Path
If the strap passes through slots in an FPV frame or around an RC battery tray, the actual path may be longer than the battery's perimeter. Measure this additional routing distance rather than assuming the strap only needs to wrap around the bare battery.
Step 3: Leave Sufficient Fastening Overlap
The strap must retain enough usable hook-and-loop engagement after passing through the buckle and following the complete mounting path. The entire nominal strap length is not available as battery circumference, and a strap that barely reaches the closure may be too short for the installation.
Choose a longer option if the 250mm strap does not provide sufficient overlap. Similarly, select 500mm rather than 300mm when the larger battery or tray requires a longer fastening path.
LiPo Battery Strap Installation Tips for FPV Drones, RC Cars and Planes
- Position the battery correctly: Place the pack in the designated mounting area, using a suitable tray or anti-slip pad where appropriate.
- Route the strap: Pass the strap through the mounting slots or around the intended support points.
- Use the buckle: Thread the free end through the metal D-ring or reinforced plastic buckle, depending on the strap design.
- Adjust the tension: Tighten the strap sufficiently to prevent movement without crushing or deforming the battery.
- Engage the closure: Press the hook-and-loop sections together with adequate overlap.
- Check the installation: Ensure the battery, leads, and connectors remain clear of propellers, gears, steering mechanisms, and other moving components.
For high-vibration applications or large and heavy battery packs, use multiple straps or supplemental battery retention when specified by the RC model manufacturer. Inspect the strap and fastening surfaces for damage or wear before use.
Frequently Asked Questions About RC LiPo Battery Straps
What size LiPo battery strap do I need for an FPV drone?
