Powerbank Li-Ion 2S3P with 5V 3A double USB Output

thingiverse

Hey there, I've got a sweet deal for you. Check out this awesome 5V 3A double USB LiIon power bank that packs about 10'000 mAh of juice, depending on the LiIon cells you choose to use. You'll need to charge it with a powersupply that can handle 2A, which is listed below. Now, let's get down to business and take a look at all the parts I used for this project. I've got them all listed out below for your convenience. One thing to keep in mind: it's better if you put the switch between Lipo (+) and BMS(+) instead of how it's shown in the picture. **Important Stuff** LiIon and LiPo batteries can be pretty hazardous, so please don't short-circuit them, overcharge them, or damage them in any way. If you're not sure what you're doing, it's best to leave it alone. I'm not responsible for any functionality issues or risks that this product/parts might pose. **Links to the Electric Components** * USB: Stepdown/Charger-Module (get it here) * LiIon-Batteries (18650): (check out these Samsung cells) * Power-Switch: (grab one of these switches) * 2S BMS with balancing: (balance your power with this BMS) * Capacity-Indicator (2S): (see how much juice you've got left) * Fuse (5A): (protect yourself from overcurrent issues) * Charger: (charge it up with this 2S charger) * Power-Connectors (female only, duh!): (connect your power-hungry devices) * Important sticker :-): (stick this on and show off your DIY skills) * Cables: (get the cables you need here) And don't forget to grab a solder iron - it's essential for this project. I used hot glue to fix all the components in place. If you've got any questions, just shoot me a message and I'll be happy to help!
