TRUEcharge3 20A 3-Bank Battery Charger - 24V delivers a compact, high-performance charging solution for multi-battery systems in RVs, boats, and commercial applications. Designed to fit tight spaces, it combines low electrical interference, a power factor–corrected multistage charging algorithm, and global compatibility to keep your batteries healthy and ready to go.
Key features
- Ultra-compact, drip-proof design for flexible mounting in multiple orientations
- Microprocessor-controlled multistage charging with two- and three-stage settings
- Three-bank, 20A total charging for 24V systems
- Battery compatibility: Gel, Flooded, AGM, and LiFePO4 (lithium-ion) support
- Parallel stacking capability with an optional remote panel
- Ability to charge batteries that are deeply discharged down to extremely low voltage
- Quiet mode option for reduced noise
- Built-in surge and spike protection on the AC input
- Power Factor Corrected (PFC) charging for efficient use of shore power
- Easy-to-read display with optional remote panel for convenient monitoring
Three-stage charging for optimum care
TRUEcharge3 uses a three-stage charging profile to maximize battery life and performance while minimizing wear. Bulk stage rapidly replaces 70–80% of the battery’s charge, Absorption stage carefully replenishes the remaining 20–30% at a safe rate, and Float stage keeps voltage stable to prevent damage and sustain a full charge over time.
Global compatibility and reliability
- Universal AC input: 90–265 VAC, 47–63 Hz for worldwide use (travel-ready and tolerant of variable power)
- Nominal output and settings for 24V systems, including charging and float voltages tuned for diverse battery types
- Battery types supported: Gel, Flooded, AGM, and LiFePO4
- Built-in protection against surges, spikes, reverse polarity, over-temperature, DC over-voltage, and circuit breaker triggering
- Drip-proof construction and wide operating temperature range (0–60°C / 32–140°F)
- Minimum recommended battery bank size: 40 Ah
- Dimensions: 70 x 170 x 250 mm (2.8 x 6.7 x 9.8 inches); Weight: 2.2 kg (4.8 lb)
- Regulatory approvals: CSA, UL, IEC/EN IP32, FCC Part 15
With its compact footprint, sophisticated charging algorithm, and broad battery compatibility, the TRUEcharge3 20A 3-Bank Charger is the trusted choice for keeping your 24V electrical systems ready—whether on the road, on the water, or at the job site.
