How Does the Harris Professional Plus Battery Work?

The Harris Professional Plus Battery uses lithium iron phosphate (LiFePO4) chemistry, providing stable energy output and thermal resilience. Its BMS monitors voltage, temperature, and current to prevent overcharging or overheating. This ensures consistent performance across extreme temperatures (-20°C to 60°C) and reduces degradation, offering up to 5,000 charge cycles—10x more than lead-acid alternatives.

What Are the Key Features of the Harris Professional Plus Battery?

Key features include a 12V/100Ah configuration, 1280Wh capacity, and 200A continuous discharge. It supports parallel/series connections for scalable voltage and capacity. The lightweight design (26.5 lbs) and IP65 waterproof rating make it portable and durable. Bluetooth connectivity allows real-time monitoring via mobile apps, while zero maintenance eliminates frequent checks.

The Bluetooth integration deserves special attention. Users can track voltage, remaining runtime, and cell balance through a dedicated app, receiving alerts for abnormalities like over-discharge. The IP65 rating ensures dustproof operation and protection against low-pressure water jets, making it suitable for marine environments. Additionally, the modular design allows up to four batteries to be connected in series for 48V systems or in parallel for 400Ah capacity, catering to diverse energy needs.

Why Choose the Harris Professional Plus Over Lead-Acid Batteries?

Unlike lead-acid batteries, the Harris Professional Plus charges 4x faster, operates efficiently in subzero conditions, and retains 80% capacity after 5,000 cycles. It’s 70% lighter and doesn’t require ventilation, reducing installation constraints. Its deeper discharge capability (100% Depth of Discharge) maximizes usable energy, whereas lead-acid batteries degrade at 50% DoD.

How to Maintain the Harris Professional Plus Battery for Longevity?

Store the battery at 50% charge in cool, dry environments. Avoid prolonged full discharges. Use a compatible LiFePO4 charger (14.6V absorption voltage). Clean terminals monthly with a dry cloth. Update firmware via Bluetooth to optimize BMS algorithms. Rebalance cells every 500 cycles if voltage deviations exceed 0.2V between cells.

How Does the Harris Professional Plus Compare to Battle Born or Renogy?

The Harris Professional Plus offers a 7-year warranty vs. Battle Born’s 8-year and Renogy’s 5-year coverage. It matches Renogy’s 100Ah capacity but delivers 20% higher peak currents. Unlike Battle Born, it includes Bluetooth diagnostics. However, Renogy’s modular design allows easier expansion, while Harris focuses on ruggedness for off-grid industrial use.

When evaluating runtime, Harris batteries maintain voltage stability better than Renogy under high loads. For example, powering a 2000W inverter, Harris sustains 12.2V for 95 minutes versus Renogy’s 12.0V for 82 minutes. Battle Born edges ahead in cold weather performance, operating down to -30°C versus Harris’ -20°C limit. However, Harris compensates with a lower price point—$899 vs. $1,049 for Battle Born’s equivalent model.
