How Does the Hopkins Towing Solution Maintain Your Towed Vehicle’s Battery
The Hopkins Towing Solution Towed Vehicle Battery Maintainer prevents battery drain in towed vehicles by delivering a controlled charge through the tow vehicle’s electrical system. It connects via a 7-way RV plug, ensuring continuous power to the towed vehicle’s battery while towing. This device is compatible with most RV and trailer setups and includes safety features like reverse polarity protection.

How to Install the Hopkins Battery Maintainer in 5 Steps
1. Locate the 7-way connector on both vehicles. 2. Plug the maintainer into the tow vehicle’s 7-way port. 3. Connect the maintainer to the towed vehicle’s battery via the included cables. 4. Secure wiring to prevent tangling. 5. Test the connection by checking voltage levels with a multimeter. Installation typically takes 15–20 minutes and requires no specialized tools.
For optimal performance, start by cleaning the 7-way connector ports with electrical contact spray to ensure proper conductivity. When routing cables, use zip ties to fasten them away from moving parts like suspension components or trailer hitch mechanisms. If your towed vehicle has a battery cutoff switch, disable it before installation to avoid interruptions. After connecting the maintainer, test the system by turning on the tow vehicle’s headlights and verifying that the LED indicator on the Hopkins unit shows green (charged) or yellow (charging). For vehicles with dual batteries, consider installing a secondary maintainer or consulting Hopkins’ technical support for wiring diagrams.
| Step | Tool Needed | Time Estimate |
|---|---|---|
| Connector Inspection | Contact Cleaner | 3-5 minutes |
| Cable Routing | Zip Ties | 7-10 minutes |
| Voltage Testing | Multimeter | 2-3 minutes |
What Safety Mechanisms Does the Hopkins Maintainer Include?
The device features reverse polarity protection to prevent damage from incorrect connections. It also has a built-in fuse to guard against power surges and automatically adjusts charge rates to avoid overcharging. The insulated cables and heat-resistant casing further enhance safety during extended use.
Beyond basic protections, the maintainer employs thermal sensors that reduce output if internal temperatures exceed 185°F, preventing component meltdown. The 14-gauge wiring is engineered to handle up to 10 amps despite being rated for 3 amps, providing a 233% safety margin. For users in coastal areas, the corrosion-resistant connectors resist saltwater exposure better than standard brass terminals. Hopkins also integrates a fail-safe voltage clamp that disconnects the circuit if the towed vehicle’s battery voltage drops below 9V, protecting against deep discharge scenarios.

Expert Views: Redway’s Take on Battery Maintenance
“The Hopkins Towing Solution simplifies maintaining towed vehicle batteries without requiring technical expertise,” says a Redway engineer. “Its integration with standard 7-way systems makes it a go-to for RV owners. For optimal performance, pair it with a quality AGM battery and avoid using it in tandem with aftermarket lighting systems, which can cause voltage drops.”
FAQs
- Does the Hopkins Maintainer Charge Dead Batteries?
- No. It maintains existing charge but cannot recharge fully depleted batteries. Use a dedicated charger first.
- Is the Hopkins Maintainer Waterproof?
- It’s weather-resistant but not fully waterproof. Avoid submerging it or exposing it to heavy rain.
- Can It Overcharge the Battery?
- No. The maintainer automatically regulates voltage to prevent overcharging.
