Storing Power for Outages/Camping

Posted on Edited on Disqus:

This project was from the beginning of 2021. It took around 40 hours over a few months. It can store around 3 kWhs and has a max output of 2500 watts peak/1500 watts continuous. It can run a campsite and be charged off of a laptop charger or solar panels/wind generator – anything that produces between 12 and 48 volts of power.

Most of the project is based on LithiumSolar's video.

Recycled 2200 mAh modem cells were sourced from batteryhookup.com. I've sourced some 2600 mAh cells but not the 364 required for this project. The total storage of the generator ended up being a little less than 3.0 kWh after testing all cells.

A kWeld was used for spot welding. 4P nickel strip was sourced to simplify connections for each parallel group.
