PowerMax PM4-60A 60A Deck-Mount RV Converter Charger — 12V Regulated Output, Lithium-Adjustable

The PowerMax PM4-60A is a deck-mount 12V converter charger that supplies up to 60 amps of regulated DC power and supports multi-stage charging for lead-acid and properly configured lithium battery banks.

Designed for RV electrical systems, the PowerMax PM4-60A converts 120V AC shore power into steady 12V DC power while delivering intelligent charging to maintain battery health. Its deck-mount format installs near the battery bank or electrical compartment for tidy wiring and efficient operation. Built-in protections and an adjustable lithium-compatible output give installers flexibility and reliability without adding bulk.

How does the PM4-60A handle RV power needs?

The PM4-60A provides a regulated 12V DC output capable of supporting typical RV loads such as lights, pumps, fans, and control systems while charging batteries. It keeps voltage steady under varying AC input conditions, reducing the risk of undervoltage to onboard devices.

• Up to 60 amps continuous DC output for running appliances and charging.
• Regulated 12V output to protect electronics and accessories.
• Deck-mount layout for proximity to battery banks and cleaner cable runs.

Can this charger work with lithium batteries?

Yes—PowerMax built the PM4-60A with adjustable output settings that let it be configured for compatible lithium battery chemistries when used with the correct battery management or a lithium-ready battery system. Always follow the battery manufacturer’s charging profile and wiring recommendations to ensure safe operation.

• Adjustable charging parameters to match lithium charge requirements.
• Works best with battery systems that include a BMS or lithium-compatible controls.
• Not a plug-and-play replacement for batteries requiring proprietary chargers—verify compatibility first.

What safety features protect the converter and batteries?

The unit integrates multiple protections to promote dependable operation in mobile environments. Thermal safeguards, reverse-polarity protection, and current limiting help prevent damage from wiring errors, overloads, and elevated temperatures.

• Current limiting to prevent excessive draw during faults or heavy loads.
• Reverse-polarity protection to guard against incorrect battery connections.
• Thermal protection to reduce risk of overheating in confined mounts.

How easy is installation and maintenance?

As a deck-mount converter, the PM4-60A installs close to the battery bank for short DC runs and cleaner wiring. The compact housing and clearly labeled terminals simplify hookup; routine maintenance is limited to periodic visual checks and ensuring ventilation around the unit.

• Deck-mount form factor for near-battery installation and tidy wiring.
• Clearly accessible terminals for AC input, DC output and battery connections.
• Minimal maintenance: inspect ventilation and wiring periodically.

Who is this for? The PowerMax PM4-60A suits RV owners, fleet technicians and DIY van builders who need a reliable, compact converter charger to power onboard 12V systems and maintain battery banks. It’s especially useful for setups that require a higher-output, adjustable charger capable of supporting properly configured lithium batteries while providing robust protections for mobile electrical environments.
