Why the RELHOST RW-24-E Uses a Removable 20V Battery
When you look at cordless outdoor tools, a common trend is clear: sleek devices powered by non-removable internal batteries, sealed inside plastic enclosures, and recharged through proprietary power adapters.
When designing the RELHOST RW-24-E Metal Hose Reel Cabinet, we took a different approach: The unit features no built-in, proprietary battery pack.
Instead, the RW-24-E is compatible with the DEWALT 20V MAX battery platform, including the DCB203 and DCB182 models. Battery and charger are not included.
Here is the engineering rationale behind choosing an external, swappable platform, how it simplifies yard care, and why it provides long-term reliability for your home.
1. Avoiding the Built-In Battery Dilemma
A freestanding metal hose reel cabinet is designed to organize and store up to 125 feet of 5/8-inch hose.
However, when motorized garden equipment relies on an internal, non-removable battery:
- The power cells cannot be quickly swapped if they degrade over seasons of use.
- Sourcing exact proprietary replacement parts can become difficult once product revisions occur.
- If an internal battery permanently loses charge, an otherwise functional cabinet can be rendered inoperable.
Separating the power source from the reel chassis helps protect your investment. With a swappable battery platform, you can replace or swap the power source with another compatible battery while the heavy-duty metal cabinet remains the central fixture of your yard-care setup.
2. Practical Backyard Logistics: No Dragging a 30-Pound Reel to an Outlet
Freestanding metal hose reels are heavy-duty by design:
- Net weight: 30.4 lbs (13.8 kg)
- Hose capacity: Up to 125 feet of standard 5/8-inch garden hose
- Anchored stability: Ground peg and bracket hardware helps keep the reel stable during winding
If a motorized reel relies on an integrated battery, recharging may mean detaching the anchor pegs and hauling a heavy unit indoors, or running an extension cord across the yard to reach an outdoor outlet. The RW-24-E eliminates that friction: simply open the battery access hatch, remove the compatible 20V battery, and bring only the compact battery to your regular garage or workshop charger.
Safety note: Install the ground peg before rewinding the hose to help keep the reel stable during operation.
3. Tool-Only Efficiency: Leverage the Battery Platform You Already Own
Many homeowners already maintain cordless tools for home improvement, woodworking, or lawn trimming. Including a generic battery pack and a proprietary wall charger with every hose reel can create redundant hardware that clutters your workspace.
By offering a Tool-Only configuration, with the battery not included, the focus stays where it belongs: on the heavy-duty metal cabinet and removable-battery design.
The RW-24-E is compatible with the following DEWALT 20V MAX battery models:
- DCB203: 20V MAX, 2.0Ah (36Wh)
- DCB182: 20V MAX, 4.0Ah (72Wh)
Simply slide in a compatible 20V pack to enable motorized retraction for your garden hose. Battery and charger are not included.
4. Cold-Weather Storage and Safe Battery Care
Outdoor seasonal changes require disciplined maintenance for both water fixtures and battery-powered equipment. According to the official RW-24-E User Manual, specific operating boundaries must be observed.
Moisture caution: Do not use the product in rain or wet conditions, and keep water away from the battery compartment and hose-feed mechanism.
Temperature limits: The recommended operating temperature is 32°F to 104°F (0°C to 40°C).
Console monitoring: LED indicators show battery charge and operating status.
| Indicator | Status | Recommended action |
|---|---|---|
| Red + Yellow + Green | 70%–100% charge | Optimal battery level |
| Red + Yellow | 30%–70% charge | Normal operating condition |
| Red only | 0%–30% charge | Recharge soon |
| Warning icon, solid | Circuit fault | Check the battery connection and contacts |
| Warning icon, flashing | Overheat warning | Allow the battery to cool for 30 minutes |
Winterization requirement: As cold weather approaches, always remove the battery and store it indoors. Disconnect the unit from the water supply, completely drain standing water from the hose and internal lines to prevent freeze damage, and store the entire reel indoors during cold and freezing months.
5. Manual Backup When the Battery Is Empty
What happens if your battery runs out of charge before you finish tidying up the yard?
With single-mode electric reels, the hose remains stranded until a pack finishes recharging. The RW-24-E includes a manual crank handle. If the battery is drained or not inserted, attach the crank handle to rewind the hose manually.
Manual rewind tip: To make hand cranking easier, walk the hose end back toward the unit so it forms a relaxed U shape in front of the reel before winding. This reduces ground drag and helps ensure smooth recovery.
