...And Makita is so damn secretive.

 

I was just thinking...it’s been quiet

Did you guys see this?  It's on their fb page.  Of course no details on the battery itself though.

There are actually several more photos of the battery on this page too.  No idea if its something new or not?

It says right in the description.

There will be no new battery because current battery technology has reached its limits and there are no viable alternatives.

20700 and 21700 are just formats, and they bring no advantages over 18650 or any other format.

The capacity and discharge current  has not improved for over 5 years in the battery industry.

Other manufacturers came up with higher capacities because they switched to bigger formats (= bigger batteries). There's no point for Makita to do the same because they would need to come up with modified tools to fit them.

 

Don't be fooled by youtube hypes about 20700, Tesla, graphene and whatever. They will show all the benefits of a new proposed technology, but leave out the limitations or disadvantages that make the adoption impossible

A new battery tech has to be superior to the current tech in all the aspects. Capacity (energy to size/volume ratio), discharge currents, lifetime cycles, flat voltage curves. Also production cost has to be low enough.

I guess I should ignore the superior power I get from my FlexVolt tools with 15x 21700 cells compared to my Makita tools powered by 10x 18650. 20x 18650 isn’t too bad but let’s get real. 21700 has a number of advantages over 18650.

While the 5.0ah with 18650 cells is pretty good combination of size and runtime there are definately tools that can benefit from higher ah batteries.  I personally think this newest wave of compact 4.0ah and 8.0ah batteries with the 21700 cells will be a game changer on my jobsites.  Makita is free to do what they want but I think they're doing their customers a disservice ignoring battery tech that's out and available.

I really hope they will come out with something soon, as you mention at least jump on the train with 4ah and 8ah LIHD battery, I mean what is the reason to have bigger gap between the battery on the new 36volt tools, at least on the latest tool I have. Today I have 2 2ah and 4 4ah battery and two dual charger, so sure that works, but don't want to buy 6ah if a newer version is around the corner.
