While the included monitor is great, for a permanent RV install, consider a sophisticated shunt-based monitor like the Victron BMV-712 for even more detailed historical data.

Tip #4: Pre-Charge Before Parallel Connection

If adding a second LOSSIGY battery in parallel, charge both individually to a similar voltage (within 0.1V) before connecting them to avoid high balancing currents.

Tip #5: Store at Partial Charge for Longevity

If storing your vehicle for the winter, charge the battery to about 60%, disconnect it, and store it in a cool place. This minimizes aging.

Tip #6: Understand Your Charger’s Profile

The included charger is a “smart” LiFePO4 charger. Don’t try to use an old lead-acid charger, as it will not charge properly and could be unsafe.

Tip #7: Leverage the Peak Power

Don’t be afraid of short, high-power demands. The 1000A peak is there to be used for steep hills or starting a large inverter load.

Common Mistakes to Avoid

1. Mistake: Using the wrong charger type. → Solution: Always use the included LiFePO4 smart charger or a verified compatible one.
2. Mistake: Installing with loose or corroded terminals. → Solution: Clean terminals with a wire brush, use appropriate corrosion inhibitor, and torque to spec.
3. Mistake: Letting the battery sit at 0% or 100% charge for months. → Solution: For long-term storage, aim for a 50-70% state of charge.
4. Mistake: Ignoring the BMS protections. → Solution: If the battery suddenly cuts off, it’s likely the BMS protecting it. Check for an overload, short circuit, or extreme temperature. Let it sit, and it may reset.
5. Mistake: Assuming it needs ventilation like lead-acid. → Solution: LiFePO4 batteries do not off-gas. They can be installed in sealed compartments, but avoid extreme heat buildup.
