12V 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)

And they are not that expensive! Super reliable battery and always on the top of my lists.

Now this battery is not that pretty, but it is the best performing 12V "smart" battery around. In my testing, it had the longest bluetooth range, zero cycling issues (like all the other "smart" batteries available) and high quality cells. The build quality is on par with a wattcycle, but does not have any of the software issues. Ecoworthy constantly updates their batteries with feedback from the forum.
Some crazy stats about this battery:
- New from the factory, these have the best cell voltage balance of all batteries I have tested.
- If I do a capacity test at .2C (56A) or with 200A, I get 290Ah and 290.2Ah, respectively. Incredible!
- I can run 200A till it dies.
- I can connect to the bluetooth twice as far as any other battery on my list. I can be in a different building and still connect. It is bonkers.
- Metal cell holders. This is usually only found in more expensive models. Build quality is on par with batteries that cost $100-$200 more.
The older version of this battery was extremely reliable. These new updates make it the best battery on my list now!

Now this is my favorite 12V battery right now. It does cost a bit, but it can charge and discharge with 300A!!! And it pulls full capacity at that rate. Best performing battery but at a price. Not for everyone, but I love mine.

These companies keep changing cells and bms without telling their customers, so this battery fixes that! What you see is what you get. I cycle tested it and it does hit high temp disconnect pretty quick, but the battery works well! And if something goes wrong, you can actually see it.
What I do not like is that it is a smart battery which means it has bluetooth.
