To fully charge a 24V LiFePO4 battery, you require a charger that provides a voltage between 28.4V and 29.2V. Using a charger with a lower voltage can still charge the battery, but it will not attain a full 100% capacity.

Trickle charging is unsuitable for lithium batteries. Charging a LiFePO4 battery with a trickle charger not specifically designed for this type of battery could result in overcharging or damage, as lithium batteries have distinct charging requirements compared to traditional lead-acid batteries.

Yes, it is possible. However, charging a battery to less than 100% and avoiding complete discharge consistently enhances cell longevity. Similarly, keeping the state of charge (SoC) within the 20%-80% range significantly extends the lifespan of lithium batteries. Power Queen deep cycle lithium batteries exemplify this durability, enduring over 4,000 deep cycles at 100% Depth of Discharge (DoD), more than 6,000 cycles at 80% DoD, and exceeding 15,000 cycles at 60% DoD.

It's generally safe to leave a lithium-ion battery on the charger overnight, especially when using chargers such as Power Queen lithium battery chargers. These chargers are designed to automatically stop charging once the battery reaches full capacity, a feature common in most modern lithium-ion chargers to prevent overcharging.

It's essential to verify that your charger supplies the correct current and voltage for charging LiFePO4 lithium batteries. For example, using a 24V charger with a 12V LiFePO4 battery is not advisable. It's crucial to use a charger designed specifically for the battery's chemistry. Moreover, when charging LiFePO4 batteries, avoid using standard lead-acid chargers that may include features like desulfation or dead battery mode, as these can potentially damage LiFePO4 batteries.
