Battery Charge Cable for a 2004 Electra Voy?

[Bob]

I received a communication from someone - and I'm stuck as to what to suggest to them. If anyone has any ideas where (on the internet preferably) they could find the item in question, then I'd love to hear them and I'll pass them on:

"where can I purchase a Battery Charge Cable for a 2004 Electra Voy? Model #88911 36V-12Ah-10hr.
EVdigest3684 this is all the Information I have.
Please Reply.
Thank you

I know this isn't much to go on, but if anyone does have an idea.

Thanks,

Bob
