Should be good. One thing, though, and it may be a killer.  You shouldn't
hook batteries in parallel except when they are charging.  Otherwise tiny
differences in the batteries will cause quite surprising currents to flow
through the parallel connection as one tries to charge the other.  The
circuit to avoid this would involve a relay or diode isolator or manual
switch on the charging side and a manual switch on the load side.
