Скачать или смотреть Are 12V 300Ah Batteries the Best Solar Power Deal in 2025?

Today on Oobies Tips, I’m back from a long day behind the wheel driving a school bus for my local school system—and I’ve got something awesome to share! I just received a set of new Yeagulch 12.8V 300Ah LiFePO4 batteries from Amazon for my solar setup, and I want to show you exactly why I chose these over the more expensive server rack batteries.

It all comes down to cost vs. capacity. For just over $600, I picked up two of these batteries, giving me a total of 7680Wh—that’s roughly 1.5x more energy than what you'd get from a single server rack battery at a similar price. Now that I’ve added four of these to my setup, I’m rocking 15,360Wh—about the same as three server rack batteries, but at nearly half the cost!

In this video, I’ll walk you through the numbers, show you my setup, and explain why this budget-friendly option makes perfect sense for anyone building or expanding their off-grid solar system.
