Help with first self designed and printed Lipo mod

[DamianB]

Hi All, hope you are all well 👍

I'm on to my second 3D printed mod !!  this is my first one, very basic, was just a proof of concept for me to figure out the building process.

My second mod is going to be using a 3s Lipo, i've never used a Lipo before, so i have a few questions about how to wire it up

There are a couple of things that i'm confused about :

The first one is to do with the balancer connector ... on the 3s Lipo i have (link) it has a 4 pin JST connector (red, 2x white and a black wire) but the JST that came with the DNA250C board (which i had already soldered on) has 5 pins.

Do i just need to remove that and solder in a 4 pin JST ?

The second query is to do with the bridging of pins ... on my first mod which used 2 x 18650's I needed to bridge taps 2,3,4 and on the wiring diagram for the 3s it shows that 3 and 4 need bridging, But on the information about using a balancer plug, it does not mention at all about the need for bridging the pins ?
Is it a case that if you're using an actual Lipo rather that 18650's, that you do not need to bridge anything ?

 

Any help would be hugely appreciated 👍  

And i will of course add some pics of the new mod soon, i'm actually printing the final case part now, but have still to make the screen holder, so very close !!

Cheers

PS i seem to be failing at inserting a picture using imgbb, any help on that would be cool too

So by using the datasheet wiring diagram, yes you'd solder in a 5 pin JST XH connector AND do your jumper for the missing cell 4. Here's a good photo
