EG4 Wall Mount 280AH 51.2V Indoor Lithium Battery
The WallMount Indoor 280Ah batteries are designed for indoor energy storage applications in low-voltage residential settings. These batteries utilize lithium iron phosphate cells renowned for their top-notch safety features, supported by an intelligent Battery Management System (BMS). The BMS monitors and logs real-time data on each cell's voltage, as well as the current, voltage, and temperature of the module. Additionally, it includes a passive balancing function and advanced battery control techniques, enhancing overall battery pack performance.

Order process flawless. Shipping was super fast.
William Tarolli
had a bunch of questions and Christian answered them. Now hopefully after using three different inverters this one will have the correct software and will solve the problem.
Thanks for the help!

I was a bit skeptical of buying from a new company first and spoke to Christian. He answered all my questions and made sure my order shipped quickly. I would buy from them again anytime, and I recommend them.
