Shark Shield DIVE01 - Charger

I recently was given a new/un-used Shark Shield DIVE01, the unit does not have a charging unit for the battery pack.

Anyone have one they don't use anymore, since upgrading?

I know this is an old unit and not support by Ocean Guardian any longer.  Would hate to see it go to waste.

Thank you.

Does it share the same two pin charger as the freedom 7?

I think I may have an old freedom 7 charger somewhere. I recently exchanged my old unit and the replacement came with a new charger.
