make your own 40v xgt case

I probably need that PC board only. Then connect to my DIY powerbank.

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

If the board just a BMS, will tap the total output from the connector. Bypass the BMS. I need the output only. Not charging.

What I worry is the additional sensing connection to the tools. This additional signal will cut off/on the tools from the battery.

Than 2nd option would be to make a separate power bank.

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.

You mean the copy makita microwave?

I find it interesting the Makita microwave. But the price

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.

Makita 40v battery clone have already in Aliexpress.

As long the powertools current surge doesn't trip the inverter is fine.

Last time my project to extend the battery AH for the worx, use 18650 and 3D print the adaptor + casing.

I looked harder in taobao and found those 40v clone.

Can look for LG HG2 3.6V discharge 20A. 10S2P =6AH.

Buy in pack of 10pcs will be cheaper.

I just notice Bosch has cordless table saw already. GTS18V-216. Its quiet. 81dba only.

My old GTS10J is 103dba.

Itchy hand liao.

A new cordless table saw or Makita cordless tracksaw + 140cm track?
Both about same price.

for wall drilling, better take rotary sds type drill. easily drill thru wall/concrete.
i will go for trusted brand.. bosch makita and others..
my self got Bosch GBH2-26DFR (was gifted to me actually ).

GSB18V-50

Set kit like this Bosch can do most of the job.

Mainly for household use.
