Choosing a BMS and charger

So the 4A charger can come with many different tips, which one should i get? Do I need the female counterpart as well? and solder it to the bms?

Yeah, you need the female as well. I’d go with one that atleast have some protection, maybe this one. There is some other threads where i read about these connectors, i have not tried this one myself but it’s probably good enough. Otherwise you could consider getting a proper high quality plug and change the connector on the charger as well, but i’d probably try this one out first

So where do i connect the port to? somewhere on the bms? Edit: I prefer a bigger port, sturdier one, which one of these is the best one or is there no actual difference other than looks?

I can choose which port I want on the charger so why not get a better one :slight_smile:

Yeah, the charging port usually connects to the battery positive and P- on the bms. But there should be a description of this for the actual bms you choose.

Also, lol. That is some unusual set of plugs. I guess you could get the XLR or the GX16 but they might feel very big. Also i’d check first for a waterproof port for the board. Even if you have a sturdy port it’s no fun if it’s full of dirt.

Yeah those are kinda random lol, which plug are you using right now? can reccomend anything?

On my raptor there is a 5.5x2.1(or possibly a 5.5x2.5). Works great so far.

So i’d probably go for that one…

But if you want a sturdy one, i’d look into something like this: https://www.amazon.com/Panel-Mount-Waterproof-Connector-Socket/dp/B00M9AF46Y

Edit: if you do look for a different one, do think about the fact that one side is conncted to a big lipo and the other to a live charger. The barrel connectors are pretty good at not getting shorted for both the male & female end.

I think ill go for the 5.5x2.1, the female plugs you sent About the BMS, I wanted a small one and 10A is enough for charging, but how can i actually buy it lol, do i need to email them and ask for a price? http://bestechpower.com/222v6spcmbmspcbforli-ionli-polymerbatterypack/PCB-D103.html should work fine right? or mabye this one?

It’s very cheap so mabye its not that reliable Edit: Just got the 5.5x2.1 charger and female plugs with the waterproof covers, thanks

Yeah sure, they both look alright.

That question is not specificly for me. It’s a generic question anyone can answer. And it’s too broad, you need to be more specific. All i can tell is to check that the wiring is correct and if the bms is ok.

Thanks I get it to charge don’t know how.I dudnt change anything I just keep plug-in and out and then the red light came on.
