Server Rack Battery Review: Aolithium VS. EG4

Why do more and more people need server rack batteries? I think it's because everyone is recognizing the importance of clean energy. Elon Musk said he would give people all over the world access to free electricity. Actually, we've been trying to do that, haven't we? We like to use solar panels to store energy for our homes. But if you don't have a properly sized battery bank, you won't be able to store the electricity that solar panels can produce. That means all your efforts will be meaningless the moment the sun sets, even if it's just a cloudy day.

If there was a battery that was rechargeable and supported solar charging and could be deep cycled over 4,000 times, you would instantly love it. Aolithium and EG4 batteries can do that. 51.2V 100Ah server rack batteries are rated up to 5,120Wh, or 5.12kWh, which means a single battery can store a lot of power.

But there are many differences between the Aolithium and EG4, and this article will give you the most detailed evaluation. Read on to find out more.
