Hello Bastoune.
Funny you should ask. I ordered it on Sunday and received it Wednesday. The case is EXACTLY the same size as my 12AH lead battery. The LifePO4 battery weighs only 1800gm! I wired it up last night and will fly with it on Sunday. I am planning on a 7-8 hour flight so it will be a good test of both capacity and how it responds to a cold soak. The charger I have for my K2 LifePO4 battery meets all the specifications for charging the larger battery. The new battery also has a built in charge level meter!

The lead battery is going to the recycler today.
