PowerMax Battery Chargers: Precision Power for Every Application

PowerMax has built a strong reputation as a manufacturer of professional-grade battery chargers and DC power conversion equipment. A privately held corporation based in Bradenton, FL, PowerMax manufactures DC converter chargers, battery chargers, power supplies, DC converters, DC-DC converters, and automatic transfer switches. Their products are trusted across automotive, RV, marine, and industrial applications where consistent, clean power is non-negotiable.

The PM3 Series: A Versatile Converter-Charger Platform

At the heart of PowerMax's battery charger lineup is the flagship PM3 Series. The PM3 Series converter/chargers are versatile, advanced power source solutions, available in output ratings of 35A, 45A, 55A, 75A, and 100A, delivering clean, reliable DC power ideal for powering electronics and appliances. These chargers can do double duty, recharging your batteries and supplying power to your load at the same time — a key advantage for anyone who needs uninterrupted power in demanding environments.

The PM3 features a 3-stage smart charging mode and fixed single output modes, accommodating all battery types including Lithium, Lead Acid, and AGM. The fixed output mode allows voltage adjustment between 13.0 Vdc and 16.5 Vdc, optimizing charging for various battery chemistries. This makes the PM3 Series especially well-regarded among LiFePO4 battery users, since the ability to manually adjust the charging voltage allows precise tuning for lithium battery packs.

PMBC Series: Professional Diagnostics & Reprogramming Support

For shop technicians and dealerships, PowerMax offers the PMBC Series battery charger and maintainer. The PMBC series is the leading power solution for ensuring exceptional battery support during vehicle diagnostics, calibration, reflash, or electronic scans, setting itself apart from standard battery chargers and jump boxes — which can overcharge or lose their charge over time — by delivering consistent voltage for extended periods to ensure accurate diagnostic results.

The output voltage can be adjusted between 13 Vdc and 16.5 Vdc to meet various vehicle battery requirements, including lithium batteries. The PMBC Series is equipped with a digital output voltage display, a 15-foot cable set with clamps, an on/off switch, and an LED indicator, along with multiple protection features such as overtemp protection, brownout input, reverse polarity, and over/under current protection.

Built-In Protection You Can Count On

Across both the PM3 and PMBC product lines, PowerMax engineers safety and longevity into every unit. The PM3 Series is protected by multiple features for a long, trouble-free life, including reverse battery polarity protection, brown-out input protection, and over-current protection with cycle-by-cycle peak limiting as well as rated current limiting to maximize the life of the charger. An integrated temperature-controlled quiet fan provides effective cooling during operation, maintaining optimal performance.

Wide Compatibility Across Battery Types and Voltages

PowerMax chargers properly charge Flooded, AGM, Spiral Wound, Deep Cycle, and Marine batteries. Products feature adjustable voltage control, low ripple output, precision charging technology, and clean stable DC power for RV, automotive, marine, industrial, and energy storage applications. Whether you're maintaining a weekend camper, running a professional diagnostic bay, or keeping a marine vessel powered, PowerMax's battery charger lineup offers a purpose-built solution engineered for reliability.
