LiFePO4 Phone Charging Power Box with Anderson Powerpoles

At the Orlando Hamcation in 2025, I was lugging around a 100Ah REDODO battery and a 12v-5v adapter to charge my phone and iPad, so I designed this as a lightweight and portable solution.

100% must haves:

• Power ports and battery monitor - https://amzn.to/3FKaMIi
• Miady 12v 8Ah battery - https://amzn.to/42moOIQ
• I use these inexpensive Anderson knockoffs with no issues - https://amzn.to/3QUkAlj
• You'll need to print one of these for charging the battery OR if you want to run this from an external battery if the internal one dies. - https://www.printables.com/model/1110757-anderson-powerpole-small-panel-mount/files
• Spade terminals for the battery (or if you mess one up) [Most of us just overpay for these from the auto store]- https://amzn.to/4clhCAb
• 16 AWG wire (You might have this around as well) - https://amzn.to/4l8IFTb

Extra Stuff:

If you don't have a LiFePO4 compatible charger, this is a nice one for low Ah batteries (You'll need to add Anderson Powerpoles to it when you get it) - https://amzn.to/4lapRmu

Notes:

Keep in mind that the BMS in the LiFePO4 batteries will shut the battery off when it is juiced out. Sometimes you have to jump start it with 12v from another source to wake it up.
