How do I charge a 3rd battery

[Invizatu]

I have 2 group 27 batteries in parallel in my Bighorn with an 80 amp converter (series 9280).
I have a group 24 battery that I use as a portable battery to run a water pump for filling my fresh water tank when boondocking.
Is there a way to hook up my series 24 via a set of jumper cables to the battery bank that would allow the battery to be charged off the converter at the same time the other 2 are being charged (off generator)? If so, where would the cables be hooked up to?
Thanks.

Just hook it in parallel with the other batteries, maybe use a connector like this, http://www.warn.com/utility/accessories/quickconnectplugs.shtml

Or you can use a pair of jumper cable as well.

Are you could add another converter and set it up to charge that one batt , if it's located in a diff part of the camper , that way if one ever goes out your not down , you always have an extra converter . Case solved

NAPA stocks those types of jumpstart cable connectors.
