Can I use a 4a 50.4v charger with a ownboards 12s2p battery? Is it too much amps? And I’m hoping I can switch a xt60 On the charger for an xt30 so it is compatible with my discharge xt30 on my battery, would that work? Thanks.

Depends on the BMS limits, it’s probably within spec but that’s a good question for Ownboard customer support.
First off, I’m a fan of XT60s on chargers. They’re easy to solder and make adapters for different charge ports, plus that way I can use any of my chargers for any of my boards.
Second, is there a reason you’re trying to make your charger compatible with the discharge port rather than charge port? Charging through the discharge port may work but will bypass all of the charging protections that the BMS is capable of.

Oh I didn’t know that, it’s more because I already have a
Lot of xt30s, and my battery-VESC connection is a xt60. I had also bought a charge port (2.5x5.5) but I haven’t found a charger that fits that, at least for 50.4v. This just seems to make sense by not needing to further solder and less complicated, but if you say that it will bypass some bms features, I’ll find a way how to use that charge port.
Oh my bad, totally mixed those 2 up, I meant charge port

I just want to make sure that a male xt30 on the charger will work with the female xt30 that is my batteries charge port.

Totally makes sense.
I don’t blame you for wanting to avoid soldering, I was the same way for quite a while. I do think it’s a good skill that IMO is worth the time and money that it costs to learn to do. There’s an awesome Soldering Guide here on the forum that details what you need to get started, IMO that’s the best way forward.
But, if you really wanna avoid soldering I’m pretty sure you can do that. With pre-made adapters (the cost of those will add up to a decent soldering setup relatively quickly though)
As I understand your battery is terminated with a female XT60 for discharge and a female XT30 for charge.
Your charger is terminated with a male XT60.
You can purchase an XT60 to 2.5*5.5mm adapter
Which will give your charger the ability to plug into a 2.5*5.5mm Jack like this:
To connect that port to your board you’ll need an XT30 to 5.5x2.5mm adapter
You could also bypass the 5.5x2.5mm connector and go straight from xt60-xt30

Yup
Thanks @Egtscs for all you feedback and I’m glad I have more options now, I think it might just make sense to change the xt60 on charger to an xt30, so it can go straight to the female xt30 on battery. and use the 2.5x5.5 jack for a future project. I just want to make that that would work- male xt30 on charger- female xt30 on batt. Could xt30 handle 4A?

Just to make sure before you go and make any errors, the battery should probably have a male XT30 on the charge port, not a female. Are you sure you’ve got the genders correct? Male connectors have pins, and female connectors have holes.

Can you clarify this for me as well, I was under the impression that the battery charge and discharge port should be terminated with female connectors, male connectors seem much more vulnerable to shorts.
They can be done either way, but I think typically manufacturers put “pins” on the power-receiving side and “holes” on the power-providing side. Of course you would just need to look at each battery to see how it’s made as it can be either way. But it seems to be common to misgender the connectors at first. Looking at them, it’s easy to think that the nylon housing that slides into the other one is the male side, but it’s not.

Got it, those are both female. Just checking.

Ok, so the charger with a male xt30 should work with the female right?

Yes, also XT30s are rated to 15a they shouldn’t even get warm at 4a.

Sorry guys, I’m still taking in information, a lot of the things I say are probably not correct

XT30 can easily do 30A continuous. The 5.5mm barrel connectors typically start getting warm around 4A or so, in my experience.

disagree.
IMO Battery side connectors should be female (socket) connectors- esk8 is a high vibration environment and having the male pin side on the board can lead to the blades of the bullet deforming inward, leading to a poor connection with the charger.
But that’s just how I do things now after this happened to a couple boards that I’ve built. Either or works, electrically
