Gainclone PS help

[hawaiihifi]

've built a set of gainclone monoblocks and was wondering if someone could help me figure out the following scenerio. I want to run two 12V SLA batteries in series to each monoblock (24V, actually 28V when fully charged). When charging, I want the batteries to be in parallel so I can use standard 12V chargers. I've been trying to figure this out for the last week to no avail using one toggle switch. Thanks in advance for any help.

IS a more complex circuit with a multi contact relay an option?

when the relay is off batteries is connected in series and to the chipamp/s

when the charger is switched on , relays are triggered and amp/s are disconnected from batteries and batteries are connected in parallel.

Thanks for the relay suggestion. I am considering that as an option but so far it seems just purchasing a pair of 24V chargers might be the simplest solution.
