Product Description
The Ultimate Power Solution for Modern Living
Meet the flagship of residential energy storage: the Balder Power 15kWh Wall Mounted LiFePO4 Battery. As a specialized Lithium Battery Manufacturer, we engineered this 51.2V 300Ah system to meet the growing energy demands of modern smart homes and electric vehicle (EV) charging needs.
Why Choose 15kWh (300Ah)?
-
Space Efficiency: Instead of hanging multiple small batteries on your garage wall, a single 15kWh unit provides a cleaner, more minimalist look.
-
Cost-Effective: Lower cost per kWh compared to purchasing multiple smaller casings and BMS units.
-
High Power Output: The 300Ah capacity supports higher continuous discharge currents, allowing you to run heavy appliances like central air conditioners and pool pumps effortlessly.
Robust & Reliable:
Housed in a heavy-duty metal enclosure, this battery is built to withstand the rigors of daily cycling. It includes a dedicated heavy-duty wall bracket to ensure secure mounting for its substantial weight.

FAQ
Frequently Asked Questions
Q: Is the 15kWh (300Ah) battery too heavy for a wall?
A: The 15kWh unit is substantial due to its high capacity. However, it comes with a specially engineered heavy-duty reinforced steel wall bracket designed to distribute the weight evenly. It must be installed on a load-bearing wall (concrete or brick) or a stud-reinforced structure to ensure safety.
Q: Can I parallel this 300Ah battery with a 100Ah model?
A: No. We do not recommend mixing batteries of different capacities (e.g., 300Ah with 100Ah) or different brands in the same system. For optimal performance, safety, and lifespan, please connect only identical Balder Power 51.2V 300Ah modules in parallel.
Q: Does this battery support Bluetooth monitoring?
A: Yes, the Bluetooth monitoring function is optional. If selected, you can download our specific Mobile App to view real-time data such as voltage, current, temperature, and cycle count directly on your smartphone.
