PowerPlus 24V 20 Amp Battery Charger and Maintainer

$359.95

Description

The Battery Tender® PowerPlus™ 24V 20 Amp is engineered for both portable use and permanent on-board installation — suited for commercial marine vessels, large diesel trucks, industrial equipment, and any application running 24V battery systems in demanding environments. IP68 waterproof, UL marine ignition protection, and full Multi-Chemistry support for both lead-acid and Lithium batteries at full 20 Amp output.

24V On-Board Charging for Commercial and Marine Applications

24V battery systems are standard in large commercial vessels, ocean-going fishing boats, heavy-duty trucks, agricultural machinery, and industrial equipment where the additional voltage provides the power density required for demanding electrical loads. At 20 Amp output, the PowerPlus™ 24V 20 Amp charges large 24V lead-acid and Lithium battery banks efficiently — recovering a 200Ah 24V battery in approximately 10 hours at full output — with ISM (Infinite Sequential Monitoring™) managing the full charge cycle and transition to float maintenance automatically.

IP68 — Installation in Wet Environments

IP68 certification provides complete dust protection and water immersion resistance at manufacturer-specified depth, exceeding the IP67 standard. The PowerPlus™ 24V 20 Amp can be permanently installed in bilge compartments, engine rooms, and enclosed wet areas where water exposure is routine. No shelter, no protective enclosure, no periodic removal required.

UL Marine Ignition Protection

Certified to not produce sparks capable of igniting fuel vapors during normal operation or connection — the independent certification required for any charging device installed in enclosed marine spaces near fuel systems. The PowerPlus™ 24V 20 Amp is suitable for installation in engine rooms and bilge areas where ignition-protected equipment is mandatory.

Multi-Chemistry: Lead-Acid and Lithium at 24V

A chemistry selector delivers the correct ISM profile for either lead-acid or Lithium (LiFePO4) batteries at 24V. Commercial vessels and industrial equipment increasingly use Lithium battery systems for their weight and cycle life advantages — the PowerPlus™ 24V 20 Amp supports both chemistries at full 20 Amp output.

ISM: 4-Stage Charging at 20 Amp

  • Initialization — Battery health check before current flows at the selected chemistry
  • Bulk Charge — Full 20 Amp output restores depleted capacity at 24V
  • Absorption — Current tapers automatically as the battery approaches full charge
  • Float Maintenance — Correct maintenance protocol for the selected chemistry delivered 24/7, indefinitely

Compatible battery size range: 40Ah to 300Ah at 24V. Lead-acid: flooded, AGM, gel cell, sealed MF. Lithium: LiFePO4.

Applications

  • Commercial and fishing vessels with 24V house battery systems
  • Large diesel trucks and commercial vehicles with 24V batteries
  • Agricultural and construction equipment with 24V systems
  • Industrial equipment requiring permanent on-board 24V charging
  • RVs and large campers with 24V electrical systems
  • Marine vessels transitioning from 24V lead-acid to Lithium

Automatic Temperature Compensation

Charge voltage adjusts automatically based on ambient temperature for lead-acid applications — ensuring complete charging in cold conditions and preventing overcharge in heat. Critical for vessels operating across seasonal temperature ranges.

Safety Features

  • UL marine ignition protection — certified for enclosed marine spaces
  • Spark-proof connection
  • Reverse polarity protection
  • Short-circuit protection
  • IP68 sealed housing
