Origin: Seattle, WA / Dev Log #001
As a DIY enthusiast based in Seattle, I spent months researching LiFePO4 battery setups for my off-grid projects. I noticed a frustrating trend: The market is flooded with misleading marketing.
Total price tags are designed to distract you from the actual value. A "cheap" $300 battery often provides less usable energy than a $400 one when you calculate the actual capacity. In the world of energy storage, transparency is rare.
I decided to stop guessing and started coding. BatteryPricing.com was born from a simple Python script designed to scrape real-time data and normalize it into a single, honest metric: $/kWh (Cost per Kilowatt-hour).
This isn't a retail site. It’s an engineering-focused dashboard. My background in software development and data analysis allows me to filter through the noise of Amazon Lightning Deals and manufacturer discounts to find the true baseline of the market.
Data is synced 24 times daily via official APIs. We prioritize precision over pageviews.
We track every brand that provides valid data, not just the ones with high commissions.
Our $/kWh calculation is public and universal. No hidden math.
We emphasize BMS and cell quality metrics because price isn't everything when it's in your house.
Behind this site is a single developer who spends too much time looking at CSV files and battery specs. I'm not a corporate entity; I'm a consumer just like you, trying to build a better power wall without getting ripped off.
If you find this tool useful, that's enough for me. If you use our links, you're helping me pay for the API credits that keep this engine running.
