Well, it's here !!
a)
..... at least in Germany ;
approx. 10 dealers are already selling on ebay; they have stock physically delivered
the battery also has a fuel gage;
colors are inverse compared to the 3,0Ah ; means what is black is now yellow, what is yellow is now black
as a very simple description
see attached picture
all Kit descriptions (model numbers) remain, if it is a 4,0AH kit the L is replaced with a M
example
dck290L2 (2x 3,0AH battery) ==> dck290M2 (same kit with 2x 4,0Ah battery
in UK word is out that all kits will be available End July;
I can't confirm if shipping to resellers has started yet
c) side comment: don't continue in this thread
NO news on a radio/charger for slide on batts
greetings
