Hey,
So you might have seen some people running the 40KSPL, which is a 16V lithium, but not sold at retail.
The retail models available are the XS15K and XS30K which have electronic balancing.
If youre interested, shoot me a message, I'll see what I can do for you.
Actually I take that back. Things arent working like they should in the metal department, thats a very optimistic time frame. Maybe set back a couple weeks
