I ordered a battery yesterday. If you still have the D5 (and charging base... they aren't compatable between my D3/D7) and want to get rid of it... I'll buy it). I use them offline, dumbed down, and they are perfect for a 1K basement or garage etc.). And by observing how the AI code works, using the Lidar ... I love them

... and optimize their placement and use.
I wish I had the source code tho' .... I would improve them ... a LOT ... or break them
Thanks!
