Powertool batteries to power inverter (mobile power station)

[China Man]

I have seen some products that you can buy off the shelves to power 230V but they are really expensive and often limited in power.

Makita brand such as BAC01 which will require a 36v battery pack that you buy separately. Ali Express usually have the 1-2 batteries small inverter of 300W which is not really useful for camping etc.

I found a 36V inverter on Ali and some ready made battery brackets with wire out, I will be starting a built thread and hopefully a video for my channel. My goal is to make one which is powerful enough to run a rice cooker (Chinese we can make a lot of dishes from rice cooker). Any one done it before?

My plan is to run 10x 5ah batteries, 2x18 in series to get the 36v and then 5 pairs in parallel, I get lots of batteries for review so I have plenty for the built. It will be a one way system as the batteries will still need to be charged via mains individually, I do have home solar and I can charge the batteries at home with excess solar or cheap rate at night.

Sounds dodgy as hell to me.

Why not just buy a power station such as - Anker power stations and save messing around with all that.

I understand as a lay person it would be crazy to make your own as you can get an off the shelve unit for around £800-£1000. I already have around 20x 5ah Makita type battery and will be getting more for free so it will be a way for me to use/test the batteries as well as a fun project. I intend to spend no more than £150 and I already have terminal crimps and big gauge cables etc.


I already have an off the shelve mobile power station but it is only 300W which is great for the odd laser engraving off site and recharge with a small solar panel, I though I would go bigger this time
