Estimate the right LiFePO4 battery direction for your project.
Tell HighLiFePO4 what you want to power, how long it needs to run, and how you plan to charge it. We will estimate battery size, voltage direction, and the next best option.

If the project includes solar, inverter sizing, wiring, or installer decisions, use the system planning flow instead of guessing from product pages.
Frequently asked questions
Is this a final engineering design?
No. Battery Finder is an educational estimate to help narrow battery size, voltage direction, and next steps before you buy products or request a full system plan.
When should I use the system-planning flow instead?
Use the planning flow for home backup, off-grid, solar-plus-storage, marine, or larger RV builds where inverter size, wiring, installation, and code issues matter.
Can Battery Finder recommend 12V, 24V, or 48V?
Yes, but it should be treated as a direction, not a final design sign-off. Large or code-sensitive systems should still be verified by qualified professionals.
