Multi-port charging connector

leamcorp · Feb 1, 2010

I have a 48v 20ah A123 pack and I use 16 voltphreak charger using anderson connector. As you can imagine, 16 pair of anderson connector is quite bulky. Does anyone know where I could find a smaller, multi-port connector I could use? Thanks.

thanks, I knew I've seen that before. Do you know where I could buy those?

Hi,

You can then wire the outputs up in series, with a 17-pin AMP 4.2mm PE plug that can connect into the matching connector on the front of the LVC board.

Three options for finding a "17-pin AMP 4.2mm PE plug":
1. Check with Mouser.
2. Google.
3. Send Gary a PM.

FYI Ypedal posted this somewhere:

I suggest a 2 pin connector externally available per cell, this makes using one
charger or multiple charger, etc.. without the need for a multiping connector ..
if one charger bites the dust you don't have to rework the connector.

FYI Those Voltphreak chargers get HOT.. hook them up alternating outward on a
strip In / Out / In / Out instead of all next to each other if possible.

20 Pin ATX Extension Cable. Cut wires in half, splice one end to the voltphreak chargers other end to the cells. I haven't tried this yet but it should be good for at least 2A.

24 pin also available.

Edit: it's probably a good idea to epoxy or hot glue where the wires exit the plugs to provide some strain relief.

from memory this use of chargers very close together had a side effect that the chargers overheated and died in some cases. Has anyone actually managed to cut the voltfreaks chargers open and mount them securely in a plastic case?
