Connector suggestion for battery

Hi, I am using an 18650 based battery pack with JST connectors for a project. The battery gets plugged to a PCB board to power the system. During field trials I realised how it’s difficult to disconnect the JST connectors without worrying about damaging the PCB board. Wondering if there’s an easy click/clip-based connector that someone could suggest me.

I have considered XT30, but they have the same issue, disconnection is quite forceful.

Hi Prithul
Whatever you use has to be polarised so you cannot reverse connection. Most are pretty tight. You can minimise this by not using a connector with any sort of retaining device. There is a bit of a trick with some of these but you would find 3 hands pretty useful. The friction of the contacts should hold in position and as long as there is little chance of pulling it out or if this happens it doesn’t matter then you should be OK.

If a connector is easy to remove it is probably no good or it would be easy to fall out so I don’t think you will have much success.

A thing to remember that “easy” is relative. what is easy for some might be quite difficult for others. I think a bit of care is the ultimate solution. Some of these connectors you refer to are quite small and that adds to any difficulty. Once again the definition of “small” is relative.

I suggest these, have used them a number of times and they work really well and not too hard to pull off. Can carry a lot of current but they are quite large.

Hi James
Yes they are good. Used to be made by Phoenix Contact.
The 5.08mm pin pitch and pin diameter might be a bit awkward to manage. Depends on the parent board.

Hi @Prithul271176

My preference for something like this is either going to be JST-PH connectors like these JST-PH 2-Pin SMD Connector (Side Entry) | Buy in Australia | CE07666 | Core Electronics we use them on our Makerverse USB-C LiPo Charger | Buy in Australia | CE08374 | Core Electronics as well as other boards, they take what I would call an excessive amount of force to be able to break them free from the board.

If you’re wanting something even more robust we have Right Angle PCB Mount XT30 Connector (MH-FC) - 2 Pack that will go through the PCB at 4 contact points, I would be confident that the actual PCB will break before they come lose from wear and tear.

I use the 3.5mm pitch part for a wide range of industrial equipment. Seems quite suitable for sparkies and tech support.
