wiring for LiFePO4

DragOnT Toronto, ON Post #: 67	Hi all, I just got a response from Ping re: wiring of the LiFePO4 (below) There’re two pairs of wires coming from the battery pack. One pair is for discharge and the other is for charge. You just need to connect the discharge wires to the controller. You must charge the battery pack through the charge wires, because there’s no charge protection and balance function on the discharge wires. If you charge the battery pack through the discharge wires, the cells could be over-charged. Best regards, Ping Does it mean that I need to make a second connector for the charger? If so, how would you go about it and make it look nice. Many thanks

Anywhooo, standard scooter inlets: http://www.electricsc... More of the same: http://www.evparts.co... Truth is, none of this stuff is ebike-specific, but generic bits widely available from electronics stores... But you have to have an existing inlet, no? Just solder up the input leads for the pack to the back of the existing inlet? Lock

You would need the bulkhead connector ("port") of opposite sex to mate with an XLR plug on the charger. Scroll down the page to see. Another option is to use Anderson Powerpoles or similar. These are higher performance fly-lead connectors that many gravitate towards after they play with ebikes for a while and discover the limitations of the others... :)

DragOnT Toronto, ON Post #: 71	Hi Rob, I have some older computer cords which some have this end": http://www.evparts.co... My concern is since I am not that handy, I would like to get ideas from everyone as what will be the best way to install / fasten the plug. If you are referring to the battery pack, no, I have not gotten it yet. I am still in planing stage. Thanks again. Edited by DragOnT on Jun 24, 2011 9:47 PM

user 12967342 Dundas, ON Post #: 63	That's an IEC power connector. Like the XLR connector, not really designed for DC power. I don't know what would be super easy to use, but I'll think about it. :)

user 12967342 Dundas, ON Post #: 64	Something like this already has leads attached but you would still have to make reliable splice connections: http://www.hobbyking.... http://www.hobbyking.... Everything else I can find requires soldering or crimping...

DragOnT Toronto, ON Post #: 72	I thought the battery charger would be one of those IEC plugs. Oh well, I guess it is better to see what comes in the (Ping's) order before I make anything at all. Bottom line, if I buy the battery pack (regardless from whom), I still need to find a good way to install/fasten the loose wires/plug(s) Thanks again.

According to the Ping Battery Wiring Guide V2.5, the battery comes with flying XLR type connectors. So unless you want to change them (I definitely would but you don't have to), you are all set. Although you will still have some connections to make...
