I’ve been helping with a swap by Email.  
Invited him to new forum.  
I’ll paste some of my replies here.

Well I decided to keep the 2002 for a while. I was wondering how much would  
your charge me for what I need to copy your Volt set up. I can do it, if I  
have some instructions.  
Thanks!

Glad to help.  
High voltage upgrade may not be safe. It works fine for me.  
You need the Volt packs. 2 X 12s 44v batteries. Ebay has great deals right  
now.  
A charger. DeltaQ reprogrammed.  
A small addition to controller wiring to accept high voltage. ~ $20 I’ll  
send it to you.  
Original cables worked for me.

New things are coming. I have a BMS-24 that allows monitoring cell voltages.  
$250  
Send me the cables that come with Volt packs. I’ll wire them for you. Or I  
can make new.

Here is one of the two pack on my bench.  
Pointing at plug.  
Monitor can come with two plugs. One for each 12 pack.  
I fit my packs outside the frame rails.  
See if you have room. 10" square footprint. Won’t fit between rails. ![](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/1X/f7c715957d7797f9c5541a0df2071eb3a2f69e8e.JPG)
