48V Budget Batteries

These batteries carry some risk. They may test very nicely and have fantastic hardware when I test them, but that can change at any time. Because they are not certified, the company can change cells or BMS whenever they feel like it. What you see in my reviews may not be what you get when you order them. They are very popular and they usually work very well, but you will never know what you’re actually getting. One more thing, if a fire is caused by these batteries, most home insurance will not cover the damages. Yikes! If you want to check out UL listed batteries that can be insured, click here.

16kWh Yixiang Vertical

This has to be the best bang for the buck on the market. Fraction of the price of the competitors, high quality cells and lots of safety features. These batteries have been the most popular on my site for about a year.

16kWh Yixiang Vertical

Space-saving vertical storage for high-capacity home power.

These things are great. I just do not understand how they are so cheap.

EVE Cells! Best on the market
Massive bus bars
3X over current protection devices: A fuse, DC rated circuit breaker and the BMS over current protection.
Takes one hour to build
Closed-loop communication that works with any inverter around
JK BMS. Very customizable and DIY friendly
Fire extinguisher built in
Large color display

16kWh Yixiang Horizontal

Same battery as the one above, but this one you can stack! If you are constrained on space, this is the way to go. In the same footprint and height, this battery can store 4X the capacity! It is absolutely insane. The horizontal and vertical models are the most popular battery on my website.

16kWh Yixiang Horizontal

Compact horizontal storage for flexible system builds.

Yixiang 32kWh

Double the capacity for demanding backup and off-grid systems.

Yixiang 32kWh

This battery is not for everyone just because of the sheer weight alone. Energy density wise, it is fantastic. But 600 lbs is no joke. I use a forklift to move mine around. Works great and I did a cycle test with it. If you have a stationary system that you do not plan to move for a long time, you can use this battery.
