Big Battery Box Build Done
In this video, I walk you through my complete DIY power bank build featuring a massive 280Ah battery capacity and solar-ready design. This project is ideal for off-grid power, emergency backup, and running appliances such as refrigerators without the high markup of commercial power stations. Why Build Your Own Power Station? I have a few other DIY setups, like my Dolly Power Station, Renogy Battery Box, & my Lights Out Kit (Links Below). These DIY builds offer some serious advantages over prebuilt power stations: Reduced power losses - better efficiency for running appliances like refrigerators Replaceable parts - no throwing away entire units when something fails Upgrade over time - spread out costs instead of one massive payment Learn how everything actually works - knowledge is power! The Build Process: I cover everything from initial brainstorming (box build vs toolbox design) through final assembly. The enclosure is built from ¾" plywood with 2" screws and wood glue, designed to handle 100+ lbs. I explain my component layout strategy with the battery centered, 2" clearance in back, 3" in front, plus side storage and an integrated fuse box. Electrical System & Safety: Why LFP batteries are actually the safest part of your system Proper wire sizing for all components Quality crimp connections How fuses protect your investment Future-proofing your design Component Layout: My system uses a 150A bus bar as the central hub (think tree trunk), with branches to: Solar charge controller (mounted in back for space/heat management) Inverter (Anderson plug for external connection due to heat) Fuse block (Second set of branches) supporting multiple circuits: AC charger (15A), USB outlets (10A), XT90 (15A), car port (15A) Practical Applications: I'm using this on a furniture dolly for portability to power my ICECO refrigerator, charge electronics, and run lights and low-power devices during emergencies. This build provides commercial power-station capability at a fraction of the cost, with the flexibility to customize and upgrade as your needs change. If you're tired of overpriced proprietary systems, this guide shows you there's a better way!
