Power Queen-12-V-Lifepo₄ batteries are the more intelligent choice for everyone who needs reliable and durable power supply. Compared to conventional lead-acid batteries, they offer numerous advantages. Here are the most important: -200 % more usable performance than with lead-acid batteries. - 1/3 light thanks to compact design. - Five times faster maximum loading speed. - eight times longer lifespan (over 4,000 deep discharges at 100 % dod). - Integrated battery management system (BMS) for additional protection. - An optional integrated heating for cold climate zones is available. - 100 % safe and reliable performance. - maintenance -free and sealed design. - Extended power with 4P4S (max. 48 V/16 units). Lifepo₄ batteries in the purchase are usually more expensive, but due to their longer lifespan, higher efficiency and low maintenance requirements, they are more cost-effective in the long run.

We offer a five-year guarantee on lithium batteries and a two-year guarantee on chargers. You can find more information in our guarantee conditions.

To protect, wear insulating gloves when connecting. Pay attention to operational safety during the process. It is recommended to first switch the batteries in parallel and then in series. To switch batteries in parallel, connect Pluspol with plus pole ( + with +) and minus pole with minus pole ( - with -). Connect the plus pole to the plus pole ( + with +) and the minus pole to the minus pole ( - with -). This increases the capacity (AH). Then switch the batteries in row by connecting plus pole to minus pole (+ with -), which increases the voltage (V). If you have multiple batteries, we recommend connecting up to four P 4 S (48 V/16 units).

Yes, you can charge a Power Queen 12 V Lifepo₄ battery with solar modules. However, make sure to use a compatible solar loader (MPPT) that is designed for lithium batteries.

In the case of bundled orders, the items are sent to separate packages, which creates several shipment success numbers. It is possible that these packages will not arrive at the same time. Therefore, please check all shipment successes on the "Shipment tracking" page to follow the other packages.

Yes, if your charger is compatible with LIFEPO4 batteries, you can easily charge your battery. You can also check that yourself. In order to charge our 12 V-lifepo4 battery, the charger must meet the following conditions: 1. It must support the Lifepo4 Battery AMODUS. 2. The charging voltage must be between 14.2 V and 14.6 V. 3. The charging current must not exceed the maximum permanent charge and discharge current strength. If these conditions are met, you can easily load the 12 V battery.

Choose a charger specially developed for LIFEPO₄ batteries with a charging voltage of 14.2 to 14.6 volts without preservation or trickle charging function. Next you should take the loading time into account. For example, a 12 V-lifepo₄ battery with 100 AH needs about 10 hours to be fully charged at 10 A, while it is only 5 hours at 20 A.

We recommend not unloading a Lifepo₄ battery to 0 %, as this can shorten its lifespan. In order to ensure the optimal performance and service life of the battery, the state of charge should be between 20 and 80 percent. A 50 percent loading status is more suitable for long -term storage.

Due to the shipping regulations for batteries, we invite them to 30 to 50 percent before shipping. So please charge the battery completely after receiving it before using it.
