[@louisbellanca9293]

Nice work. I ve built many battery power boxes like this. A few tips: 1-Use a USB C to 3S charger. Simple cheap and universal. See Aliexpress 2-To secure batteries, use double sided tape and tie straps instead of hot glue - you dont want those batteries coming loose. Wrap battery in Kapton tape. 3-Do not let the batteries in series touch use spacers or insulation between 4-You do not need the diode on the output 5-Include a small LED battery voltage readout after the switch so you can estimate state of charge of the box. You can add a push button activation to reduce idle current loss.

[@homemade_101]

[@tamer-H]

@@louisbellanca9293Why was the diode put on the income

[@louisbellanca9293]

@@tamer-H Some chargers will allow a backfeed into the charger. If you use a charge board the does not block (like a XL4015 -good choice BTW) or you direct connect like he did and you use for example a DELL laptop charger then you need the diode. I found out on my last build luckily my BMS was current limiting. If the charger is not plugged into AC it can backfeed - so you need to test that case.

[@SireSquish]

Also, you'd then have to re-adjust your buck/boost converter to compensate for the 0.6V forward diode loss as well.

[@niclas.lindstrom]

You should have used a charge controller dc-dc board on the input instead of that boost converter on the output (or both). A slight variation in output voltage is usually not a problem and your router will handle that, but your cheap bms will absolutely not handle cell over voltage nor thermal runaway. A bms is NOT a charge controller but a safety device supposed to protect your battery in case of charge controller failure, which your device always have (as there is none).

He's using a special power adapter, with an output of 12.6V, for direct charging of 3S battery packs. So, this all works, and it will work safely.

[@hycron1234]

I've powered a ADSL/VDSL router using a car battery or a 12V 7200mAh battery (commonly used for alarms or UPS systems). In certain cases, routers don't actually need the full 12V to operate, as they internally step down to 3.3V. This means that in some instances, you can run them on 5V (just make sure you have enough amps - power banks yes, usb ports no). Now just need a UPS for Starlink 🤔

[@homemade_101]

Starlink good yes it is no need

[@huseyinozkaya2910]

The diode you use at the output cuts 0.7 volts, the 12 level you set decreases to 11.3, so you should set it to 12.7 so that you have a 12 volt output. Greetings, colleague.
