Need connector for my Bestech BMS


I have a Bestech D223v1 10S BMS, i bought from a user of this forum. But i`m missing the two connectors for the ballancing ports. I dont know what the connectors is called, and where to buy them (im from EU)

Any help :slight_smile:

No, it’s a 10s bms Pins 1-8 on the left Pins 9-10 on the right The e/ switch is 2 white wires soldered to the pcb

You will have to contact Bestech and order the connectors or remove the sockets and solder your balance wires to the pcb. If this was a new bms, it should have come with connectors. Maybe the seller forgot to pack them.

Thanks for clarifying!

I bought a new one according to the seller. Then i must contact bestech

Send me your address i have set just pay me the shipping


I think the seller should have them in a bag that comes in the with the bms if u have no luck let me know

Contact the person you bought it from first. He should have included the connectors

Those look like “JST-XH” connectors

The 8-pin version is sometimes referred to as “7S”. 2-pin might be called “1S”

I thought the same, that these were JST-XH, the same as used on lipo batteries. But its not.... they dont fit.

Oh, my BMS from another vendor is different. Then in that case it is probably JST-PH

What’s the pitch between pins?

2.5mm JST-XH 2mm JST-PH (most likely this one) 1.5mm JST-ZH 1mm JST-SH

2.5mm same as JST-XH But the plastic connector does not have the same form facter like my regular jst-xh connectors on my lipo batteries

So, here is what I would do.

Basically, pull the plastic off the pins and connect JST-XH.

Or, alternatively:

tear the plastic until JST-XH fits :slight_smile:

You mean hack it chop it bend it till they fit

Should have asked u to sell this one

Why bend it if the pitch is the same.
