Long time no post in here already.
Adding this new toy to my makita family of tools. A 40v blower.
The handheld blower I use for PC cleaning keep dying due to battery issue. So decide to spend more to get a good blower and be done with it.

Tools from 40V and 40Vx2 family are equal power to normal AC power now. Especially the vacuum cleaner.

Just a counter point to consider.....

I wanted an air compressor to put in the car and wanted to get the Milwaukee M12 compressor (because I already have the batteries) In the end I decided not to as it would tie up a battery in the car, and there would be a worry of the battery going flat, heat damage to the battery, etc. In the end I got a Xiaomi corded air compressor (~RM 160) that I can safely keep in the car, always ready to plug into the car 12V, and works perfectly.

Maybe you really, really need the portability, and there is a use for the battery air compressor that I am not utilizing, but I am happy that I have the corded Xiaomi along with my car all the time. In the house I have a 2 HP air compressor anyway. So, just sharing my experience, YMMW.

Their is a buttom on the side, press it and it will hold the trigger to continue blowing.
very nice to blow the dust in my PC and mining rigs. No need to pull the compressor out from the storeroom.

today completed my solid Australian wood window frame using the power tools in the workshop.

Long time no update on Makita power tools so I go youtube search for what 40V system makita has.
Then see this makita 40v microwave, and I tot makita coffee maker is already wierd enough. 

Those 40v and 40vx2 system is starting to go into the power of AC tools liao. In Japan their standard AC voltage is 100v?
When makita will make 40v AC inveter? I think Dewalt has it.

make your own 40v xgt case

dont see how just the board will make it work. the board needs wire inputs from all the cells for loadbalancing and voltage sensing. so if you have different number of cells in your diy bank...u will need to rewire the whole internals

Interesting, looks like china will have clone makita battery available soon.
Original Makita 40v battery so expensive.

Price of the cordless microwave apear in taobao already, around rm2.6k. 

I mean the 40V battery, now still hard to find clone one in Taobao, only find 2 seller selling the BMS + casing + connectors, but have to find battery and spot weld myself. Ready made unit not available yet.

Another thing I am thinking of building, get a 48v 3KW  inverter and use 3 x 18V battery as power source. Taobao got sell makita battery mounting.
Should have enough power to run a table saw?

Samsung INR21700-50S continous current 15A, Peak 29A. (18vx3)x15A = 810W.
I think need 6 x 18v run in palleral to be able to run a table saw safely. 
Ouch, expensive.

how to drill a 30mm hole on a Tiles? what accessories do I need?

For all the above that you mentioned.Im kind of like to DIY myself
Not apartment.Landed house

so quiet..
anyway just arrived..4th july sales.

more flex incoming next few weeks...

buy for fun. top performing cordless hammer drill in the market.

for hammer drill the 40v makita lose to this flex 24v.. u say leh

i think the 40v tools is good but no point to spend top money as i dont need the extra power

using 18v 36v makita, and m18 m12 milwaukee mostly... already covered most of my requirements.

I wonder how is the performance between Bosch's 18v BITURBO vs Makita's 40v system.
