Build your own beast: Benefits of massive recycled battery packs

In a world reliant on portable power, DIY enthusiasts create high-capacity power banks from repurposed laptop batteries, offering unmatched performance for off-grid needs.
The video from Gabor Makes showcases an impressive homemade power bank built from over 100 recycled 18650 lithium-ion cells, each rated at 2,200 mAh. Organized into four parallel packs with individual Battery Management Systems (BMS), this setup ensures safe operation by monitoring voltage and preventing hazards like overcharging or fires. The result? A robust ~28-56V battery capable of delivering up to 80 amps—far surpassing commercial power banks.
What makes this "powerbak" so appealing? Its sheer power and portability. Weighing around 6-7 kg, it's carryable and powers heavy loads via an inverter, as demonstrated by running a 500W floodlight effortlessly. No more extension cords for outdoor tasks like gardening or workshops. It delivers around 2.2 kW for short bursts, ideal for tools or emergencies.
Benefits include cost savings from recycled cells, customization, and eco-friendliness by reusing batteries. With proper BMS and holders, it's safer and more reliable than many off-the-shelf options. For hobbyists needing serious juice without grid access, this DIY approach is empowering and practical—proving big power doesn't require big spending.
