Powermega Wall-Mounted Energy Storage Battery is an easily expandable lithium-ion battery storage system for residential use. Single configuration is on 5.12kwh with 48V or 51.2V 100Ah LiFePO4 battery. The capacity can be flexibly expanded in parallel up to 51.2kWh. It fits on the wall and provides homeowners with the ability to store electricity generated by an on-site solar system or from the grid. It provide you with backup power when you need it most. Whether you want to save money on your electricity bills, reduce your carbon footprint, or have more control over your energy usage, this energy storage battery can help you achieve your goals.

*【Automotive Grade Lithium Battery】 Powermega energy storage battery have exceptional quality with Automotive Grade LiFePO4 Cells with higher energy density, more stable performance & greater power. Highest-level safety based on UL testing certificate for the cell inside the battery. With no acid in the battery, you’re able to safely mount in any position.

*【Battery Management System (BMS) & 100% Protection】 Powermega Wall-Mounted Energy Storage Battery has built-in BMS (Battery Management System) to manage and protect various aspects of the battery, optimizing battery performance, enhancing safety, and prolonging the battery’s lifespan. It integrates multilevel safety features including overcharge protection, over-discharge protection, over current protection, overvoltage and undervoltage protection, temperature protection, cell balancing function and floating charge function.

*【1/3* Lightweight】 Powermega Energy Storage Lithium LiFePO4 Battery weighs only only 1/3* the weight of lead acid batteries, which makes it an easy choice for RVs, Marine and Off-Grid Applications when mounting or mobility is in the consideration.
* 【Copper Bus Bars】The connections between cells are made from 100% copper bus bars, which results in a very low internal resistance. Less internal resistance means less heat when the battery is under load resulting in better performance. 

* 【10 Years lifetime】Powermega Energy Storage Lithium LiFePO4 Battery provides 6000+ cycles, which is more than 10 times to Lead Acid with 200~500 cycles. It has a 10-year service life, three times longer than the Lead Acid’s 3-year lifetime.


Powermega Wall-Mounted Energy Storage Battery is widely used in residential energy storage systems, backup power solutions for homes and small businesses, demand charge management for commercial facilities, support for renewable energy microgrids, and UPS, EPS, telecom ect. It has following benefits:
· Making full use of clean energy. The impact to the power grid and users, which is consulted by intermittency of new energy can be effectively overcome.
· Providing uninterrupted backup power to users. Can satisfy the requirement of users under the extreme environment, such like the power failure caused by earthquake and flood.
· Saving electricity for users by peak-shift. Under the price of peak valley, if the power consumption is big in the rash hour, this system can help to save expenditure by storing electricity during the electricity troughs, and using in the peak time.
