Power Queen LifePo4 12.8V 50Ah Lithium Battery

Today, more and more fishing boat owners turn towards Lithium-Ion batteries to allow them to do everything a Lead Acid battery can do, only better and for longer. What each and every one of us wants, is a battery that’s strong all day long, even when its capacity drops below 50%, with a much longer life cycle, that can recharge more times and is environmentally friendlier. That’s the Lithium-Ion advantage.

Power Queen Lithium Iron Phosphate Batteries are light weight and easy to carry and install. They have low self-discharge rate and efficient power storage, which can save your charging time compared to the traditional SLA battery. 

In most cases, Lithium-Ion battery technology is superior to Lead-Acid due to its reliability and efficiency, among others.

• Power Queen LifePo4 batteries offers 10 years lifespan and 4000 - 15000+ cycles compared to the 2 years lifespan and 300+ cycles of a lead-acid battery. Compared to the 50% (Depth Of Discharge) DOD of lead-acid battery, Power Queen 12V LiFePO4 50Ah battery offers close to 100% DOD - with the exception of the safety level - which is almost twice as much useful capacity. Therefore, a single 12.8V LiFePO4 50Ah battery has a usable capacity, almost equivalent to that of a single 12V 100Ah lead-acid battery.
• Power Queen LifePo4 50Ah battery weighs about 5.24 kg and has dimensions of 19.8 x 16.6 x 17 cm, which means a lot less weight and smaller size, compared to a 50Ah AGM battery system. By using LiFePO4 batteries, you save a lot of space and weight compared to a lead-acid battery system with the same usable capacity.
• With advanced BMS, Power Queen 50Ah LiFePO4 12V battery has 5 protections to ensure safety and extend battery life. Power Queen 50Ah LiFePO4  battery has a lifespan of 10 years compared to a 100Ah lead acid battery which has a lifespan of 2 years.
• The BMS also supports 0.5C (25A) charger that needs only 5 hours to fully charge a 50Ah battery, with a 10A charger, compared to Lead Acid which needs 10~11 hours to be fully charged.

To summarize Lithium batteries perform better and last longer than many lead-acid batteries. They weigh less and take up less room. They can provide a higher percentage of nominal capacity than lead-acid batteries, without shortening their life. They maintain voltage through almost all the discharge cycle. Lithium batteries last up to 10 times longer than their lead acid counterparts and they still provide 80% capacity after 2000 cycles.

Lithium batteries have to be charged with a special charger. Although any commercial Lithium charger can be used, their longevity and smooth operation require the use of a specialized charger. The Power Queen LifePo4 12.8V 50Ah battery is suggested to be charged by the company's 10A charger.

If you connect your Electric Anchor to a Lithium-Ion battery, while fishing, then a useful accessory that will continuously feed the lithium battery with current, is a Li-Ion battery Charge Controller. The Li-Ion Battery Charge Controller is connected between the Lithium battery and another energy source, which in most cases is a Lead Acid 12V – 36V Battery, or a Solar Panel.

Note: The Power Queen LifePo4 12.8V 50Ah battery, cannot be used as a starting battery.

Each Power Queen Lithium is covered by 5 years Warrantee and carries a unique Serial Number.
