With regular use at 80% Depth of Discharge (DOD), the 12v 100ah lithium battery lifepo4 offers 6,000+ cycles, equating to up to 10 years of reliable serve, significantly outperforming lead-acid alternatives.
VTCBATT supports three fast and efficient charging methods:
AC charger: Ideal for home and RV use. We recommend a 14.6V LiFePO₄-compatible charger with a current of 20A–50A.
Solar panel: Compatible with MPPT solar charge controllers. A 12V solar setup with appropriate voltage regulation ensures stable input.
Generator: Suitable for off-grid or emergency charging when paired with an AC charger or inverter setup.
This charging flexibility allows the 12v lithium battery to work seamlessly in home backup systems, recreational vehicles (RVs), off-grid cabins, and mobile power stations.
To fully charge a 12V 100Ah battery (which holds about 1.28kWh), we recommend solar panels totaling at least 300W–400W, depending on sun exposure. Pair with an MPPT controller set to LiFePO₄ mode for optimal results.
With a 20A LiFePO₄ charger, it takes approximately 5–6 hours to fully charge. Faster charging (up to 100A or 1C rate) is supported, but always check your system’s specs to avoid overcurrent issues.
