Im looking at doing a project to light some 12v LED strip ideally to be ran at 9v and I’m in search of a rechargeable battery that is super compact. I found the 2Ah lithium Ion battery 3.7v https://www.sparkfun.com/products/13855 and it seems great except for the V I’m after.
Can anybody suggest something that can meet my requirements OR is there a way to link two/three of these batteries together to achieve a higher V output? This isn’t ideal as of course this starts to become bulky.
The brief is a to find a rechargable battery with as slimest profile. So any alternative solutions welcomed.
Hello, and thanks for posting!
You’re going to need at least three cells to light a 12 volt LED strip. If size is important, you can use smaller cells, but keep in mind that the smaller your battery is, the shorter time it will last. You could connect three of the 2Ah (or smaller) cells together in series to get roughly 11 volts like in the photo below.
The issue with this setup is that you’d need to disconnect and charge the cells individually since we don’t make a charger that can handle three cells in series. As long as you’re handy with a soldering iron and can solder some JST sockets to a small PCB this would work.
You could use three of our batteries, but it might be easier for you to go to a hobby shop that carries RC batteries and chargers and use one of those rather than trying to build your own battery pack.
Thank you @TS-Chris . That’s exactly what I needed to hear. I shall definitely look into RC batteries as an alternative too. Thanks again!
