Wiring diagrams here indicate both batteries are charged by the same ckt. Seeing as the 2 batteries are very different in size, this seems like a rather fundamental design flaw - with lots of posts to this forum confirming. Be ready to replace both batteries more often - is the result, IMO - both will wear out faster - basically as they drain and charge each other, cycling both more than a normal battery is cycled.
