Why we love it?
These are decent 9v battery connectors, reasonably constructed for the price. “,“width”:“460”}” style=“position: absolute; top: 2px; right: 0px; display: inline-block; font: 11px Arial; color: rgb(0, 75, 145); cursor: pointer; text-decoration: none;” data-action=“a-modal” class=“a-declarative”> Ad feedback
Some comments about this we saw on the web:* /u/redeyealien on /r/BurningMan for power source, if youre feeling savvy enough, i recommend a 3s RC lipo battery. Lots of power and last all night. But these can be a hassle to charge and you dont want to drain em too low or they can start fires, so i ALSO recommend something like this:
You still want to be careful charging/discharging these. Ive used both for several years and some are still going. QC can be a crapshoot, and i wouldnt expect a whole lot of cycles, but itll give you 12v for a few hours and you can recharge em while you sleep. i used it on this project: https://www.youtube.com/watch?v=ba2pyNuk7iI
soooo, just grab a few of these 9v to barrel plug connectors and a handfull of 9v’s and youre good to go. ;)
id say thats as lightweight as u can get.
