I have bought a Shindengen from a guy in the USA who came highly recommended on this forum. I haven't even unpacked it yet, so unsure of what precise model it is, but it will be able to deal with Lithium.
I hear Lithium is more ... 'fussy' than a normal battery, but I simply do not have the space for a large battery, so I am thinking of indeed going with the Ultrabatt. We'll see.
