A powerful DIY power bank that can output more than 200w for only $95 in raw materials, while all other commercial solutions cost 300+ dollars. Highly portable and features DC 5-55V, AC 110V output, which can power virtually anything below 200W. Disclaimer: I am not an electrician. Attempt this project at your OWN risk. Lipo battery can easily catch fire and explode if mishandled. This project requires a more than basic understanding of electronics to complete. Also, I'm aware that the battery bank in this video is technically 20,000mah @ 11.1v. However, it is still the exact same amount of power as 60,000mah @ 3.7V; I used 60,000 mah to better express the sense of capacity to the average viewer. (Since nearly all commercial power banks measure mAh based on 3.7v) 3D printing files: https://www.thingiverse.com/thing:3080883 Part links: (some are affiliate) Battery: https://www.ebay.com/p/Quality-3-7v-10000mah-Lipo-Polymer-Li-ion-Battery-for-Power-Bank-Case-Mobile/28004261591?iid=162494961050 DC 12V to 5V:https://amzn.to/2TEnPxT DC-DC boost:https://amzn.to/2E1GsGU 12v inverter:https://amzn.to/2WQZSpg Lipo balance board:https://www.ebay.com/itm/3S-packs-11-1V-12V-20A-Lithium-Battery-Protection-BMS-Board-W-Balanced-Charging/183214217328?hash=item2aa86b1870:g:d1UAAOSwQHFZkRwK DC-DC step-down with constant current: https://amzn.to/2DpD9I0 Diodes:https://amzn.to/2MUCpPg Mini Voltmeter:https://amzn.to/2DlvZEG Temperature control switch: https://www.ebay.com/itm/KSD9700-Temperature-Switch-Thermostat-Thermal-Protector-Normally-Closed-Open/292110026379?hash=item44031d468b:m:mLtQZk5fCWDJCewAbYAMwUg Fans, XT30 connectors, and switches are salvaged from old electronics.
