2 Easy DIY Battery Organizer Shelves for UNDER $5!
In this easy DIY project, I''ll show you how to build 2 different styles of battery-organizing shelves—both for less than $5—to fit nearly any workshop or garage layout! 🛠️🔋 Whether
Lay out your battery configuration first. Spot weld nickel strips across all positive terminals, then across all negative terminals, depending on your layout. You can then add two main output wires: one from the positive terminal strip, and one from the negative strip. These will connect to your charging board later.
Most DIY power banks use lithium-ion (Li-ion) or lithium polymer (LiPo) batteries because they pack a lot of energy into a small size. A single cell usually provides 3.7V. 18650 Li-ion batteries are the most common—cylindrical, widely available, and easy to work with.
The charging board manages battery charging and controls the power flow to your devices. It usually includes: BMS (Battery Management System): Protects batteries from overcharging, over-discharging, and short circuits. It's a must if you're using unprotected batteries. Boost Converter: Raises battery voltage from 3.7V to 5V for USB output.
My DIY power station has 1,464 watt hours of energy using a 122 amp hour flooded lead-acid battery from Wal-Mart. This battery is no longer available, however you will find alternative 100 amp hour AGM and LiFePO4 batteries linked below.
