300 amp hours. 12 volts. A footprint barely bigger than a Group 31. And it just delivered 315Ah on a capacity test — 105% of rated. Eco-Worthy may have just quietly built the best value 12V LiFePO4 battery on the market.
I run this Eco-Worthy 12.8V 300Ah through the gauntlet — full capacity test with a Victron SmartShunt, heavy continuous load up to the BMS trip point, massive surge test with a 15,000 BTU AC, freezer low-temp charge protection, the Bluetooth app walkthrough, and a hands-on test of the color-changing terminal heat stickers. Here's what shocked me, what to watch out for, and why this thing is making legacy 12V brands look overpriced.

NOTE: Since I got my hands on my sample battery, they have increased the battery capacity to 314Ah. Everything else about the battery stayed the same.
