My latest 2025 Budget Battery Find! These batteries keep getting cheaper and the quality has been going up. Recently I reviewed a wattcycle 12V battery and was blown away! This has the best build quality around, and it is cheaper than most of the budget batteries below. Pretty incredible!

It looks pretty large, but a 300Ah (280Ah) battery looks a bit small size and indeed it is smaller than you would expect. And, that's why they're calling it a mini battery. Anyway, the battery pretty much has the capacity, the answer is it ran that heater for over 6.5 hours straight!

They are packing the power up NICE and DENSE inside of this battery, what I found out is that this battery's low voltage cut-off is at 9.2V instead of the typical 10V that we've been used to for the past couple of years. They are packing a lot of energy into a very small space.

WattCycle 12V 300Ah (280Ah) Mini battery, this thing is absolutely insane at 3840Wh (3584Wh) worth of capacity. This thing is a beast of a battery in a very very compact format.
