Lost Ebike charger

The plug looks like this with 3 holes does anybody know what type of plug it is
I have a barrel type charger I would like to modify to a 3 hole if I can get the plug.

Looks like XLR audio jack. Could also be DIN 3 pin. Nobody should use 3 pin for DC.

Pretty generic, mine had these plugs but i cut them off and changed them to the ones my batteries needed - lots on ebay, just ensure the cut-out is at precisely the correct voltage (54.4 on my 48v batteries, which use RCA type plug).

Grin Technologies says:

"The XLR plug has been used in audio equipment for decades and is available in various pin configurations. In the ebike scene it's been used on battery chargers since as long as we've been doing this (2003). Back then we were mostly dealing with NiMH and NiCad batteries which require a temperature sensor for charging, and so a 3-pin XLR plug was used, with Pin 1 = V+, Pin 2 = Gnd, and Pin 3 = Thermistor. This same 3-pin configuration is also used with lithium and lead acid batteries that don't require a temperature sensor, and in that case the 3rd pin is either not connected or used as an interlock pin.

Generic quality XLR plugs don't have very good current handling for their size, and will often melt and distort when used above 4 amps or so. Higher quality XLR plugs like the Neutrik XX brand that we use on the Satiator are rated for 16 amps, which makes it an excellent choice for high current charging."

If you're in Vancouver, you can also get Neutrik male XLR from RP Electronics in Burnaby, BC:

I upgraded my battery pack to Neutrik female charging for a future Grin Satiator charger. Grin sells one rated at 16 amps!




Custom battery pack with XLR charging port, Rosenberger magnetic power out, Luna on/off switch, and Grin polyfuse for electrical accessories.
