If you fly small drones like the Blade QX Nano at home in your livingroom or any other tiny whoop, you end up with the problem having a lot of 1s batteries but no 1s battery checker. There are a ton of checkers out there, but most of them need at least 5V to operate - 1s only has 3.7 to 4.2 V...
so up until now I used a standard multimeter to check it or have the lipos checked by the charger.
But that is clumsy to do so I created my own little DIY 1s lipo checker (well, you could use it for all other types also, but there is already something available, right )
Now lets put all together. Which is also quite simple:
if you want, you can add a little hot-glue to the lid.
At the end, it looks like this:
Have fun building it!
PS: with the same principle you can build a 4s checker. Well, there are a lot of good ones out there, but I created one, I can also connect to a balancer board (because it has both a male and female 4s balancer plug):
this way I can monitor what happens on my parallel charing board when connecting the lipos and even see what happens during charing and balancing. Pretty cool...
