How Does the SU LiFePO4 Battery Compare to Lead-Acid Alternatives?
The SU LiFePO4 battery outperforms lead-acid batteries with a 4x longer lifespan, 50% weight reduction, and 95% depth of discharge (vs. 50% for lead-acid). It maintains stable voltage under load and charges 3x faster. Unlike lead-acid, it requires no maintenance and operates efficiently in temperatures from -4°F to 140°F.
When considering total cost of ownership, the SU battery’s 4000-cycle lifespan translates to 10+ years of daily use compared to 2-3 years for conventional AGM batteries. Its resistance to sulfation and corrosion eliminates the need for periodic equalization charges. For marine applications, the lithium battery’s vibration resistance and non-spill design reduce corrosion risks in saltwater environments. Users can also reclaim 30-40% more usable capacity compared to lead-acid systems due to the deeper discharge capability.

Can It Be Paired with Solar Panels?
Yes, with MPPT charge controllers (30-100V input). The 100Ah capacity stores 1.28 kWh, sufficient for 300W solar arrays. Includes MC4 connectors for seamless solar integration.
When configuring solar systems, users can achieve optimal performance by pairing this battery with 400W panels using a 40A MPPT controller. The battery’s 3A charge acceptance rate allows it to capture 360Wh daily from solar input under ideal conditions. In off-grid setups, it supports parallel connections for capacity expansion up to 4 units (400Ah total). The built-in low-temperature charging protection prevents damage when operating below freezing, while its 140°F thermal cutoff protects against desert heat. For hybrid systems, the battery works with grid-tied inverters to enable peak shaving and load shifting capabilities.
Why Choose a Built-In BMS and USB Ports?
The integrated BMS prevents overcharging, overheating, and cell imbalance. USB ports eliminate external adapters, providing 5V/2.1A output for simultaneous device charging. The 12.6V/3A charging input enables rapid replenishment via solar panels or AC chargers.
What Safety Certifications Does It Hold?
Certified to UL 1642 (lithium batteries), UN38.3 (transport), and CE/RoHS standards. The flame-retardant ABS casing and thermal cutoff switches ensure compliance with marine and RV safety regulations.
“The SU battery’s 100Ah capacity with USB outputs bridges the gap between power storage and direct device charging—a game-changer for mobile off-grid users. Its 3A charge acceptance rate maximizes solar harvesting efficiency.”
