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 youre actually getting. (Affiliate links below)

The Yixiang Vertical Mount Battery

I cannot believe how nice this battery is for the price. It has better features and higher quality components than batteries that are more expensive!

The bus bars are huge, the cells are EVE (the best you can buy) and there are three over current protection devices: A fuse, DC rated circuit breaker and the BMS over current protection.

This battery takes about an hour to assemble, but it is by far the best bang for your buck options around.

Horizontal Stack Yixiang (most popular!)

Same battery as above, just a different form factor. If you need your packs against a wall with less footprint, use the battery above. If stacking them up makes more sense, this version is for you.

Update: Been running this model for the last week and it is fantastic. I like it better than the one above. There is no stress on the terminals because the cells are facing up and it is easier to move around. Also pulled really good capacity.

600lb 32kWh Yixiang

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.
