Yes, Power Queen LiFePO4 batteries can be charged to 100%. LiFePO4 batteries are designed to tolerate full charges without significant risk of damage. However, for optimal longevity, it is often recommended to keep the battery's SOC between 20% and 80% during regular use.

Yes, you can connect these batteries in series and parallel to increase the capacity.

Note: To connect batteries in series or parallel, they must meet the following conditions:

They must be identical batteries with the same capacity (Ah) and the same battery management system (BMS).
They must be of the same brand because lithium batteries of different brands have different BMS configurations.
They should be purchased within a tight timeframe (ideally within one month).

Yes, a 12V deep-cycle battery is ideal for marine use, powering trolling motors and onboard electronics. Power Queen's lithium trolling motor batteries are designed for harsh environments, ensuring reliability on your boating adventures.

No, 12V lithium-ion batteries require a special charger for lithium-ion technology to prevent overcharging and ensure safety.

Compared to conventional 12V lead-acid batteries, 12V lithium batteries offer better performance, longer lifespan, and faster charging. They are also lighter and more efficient.
