I test, open, and review lithium (LiFePO4) batteries so you don’t have to guess. Below you’ll find my current recommendations and batteries to avoid, grouped by voltage and capacity.
12V 100Ah batteries
The most popular size for RV, van, and small off-grid solar builds. I’ve reviewed several and picked the best.

12V 100Ah+ batteries
For larger off-grid systems, bigger RVs, or anyone who wants more storage in a single 12V battery. These include all 12V batteries above 100Ah.

24V batteries
A step up in system efficiency over 12V, popular in larger solar and marine setups. Lower currents mean thinner wiring and less heat for the same power output.

48V 100Ah batteries
The standard choice for 48V home solar and off-grid systems. Higher system efficiency and lower cable losses.

48V 100Ah+ batteries
Large-scale storage for off-grid and backup power systems. These batteries are 5kWh+ and are heavy. These can also be a DIY battery.
