Thanks for the suggestions. I initially considered using NTC resistors but was too afraid of them burning them up or adding too much resistance. It's on a timer, so every time a worker pushes the button it runs for 15 seconds. Sometimes it's run right after (after about 10 seconds) more often...

It is outputting 80v ac and rectifying to whatever DC voltage. The issue with the soft start is the 400V phase to phase I can't use a 230v tool soft start. Other 400v soft start devices have 3 phase input and I don't know if that will work with a 2 phase load.

I have seen some slow start or soft start devices for 3 phase electric motors, but I need something for a two phase AC 400v Transformer that has a motor connected to it. The output is about 90v, which is connected to a rectifier that is then connected to a DC motor to drive a cart. The issue is...

If you're that cheap then you might as well tape a $20 smartphone to the door. There are apps for surveillance like Alfred camera with motion detection.

You sound just like my younger brother when he's caught lying. 🤣 Look I really hope you get to bring this out to market. Just watch your back, big oil has their eyes on you.

I've tried as well and have had no success with any flipsky controller when it comes to encoders.

I destroyed a Kelly with a incorrectly soldered xt90 once, it didn't destroy the connector like that though. Whatever BMS is inside that pack it's not that good at detecting a short circuit event I would have no hope that the controller still works but might as well connect it right way around...

I have a 80v mower and my brother has a 40v mower. I added a custom battery in parallel on our mowers and for him I bought 2 AliExpress clones for even more cutting time. They had less capacity than the original but worked for 2 years until the nickel plated steel strips and cells started...

I've never heard of a 18650 explode during normal use. It can happen when there is no BMS and one or more cells are unbalanced and get charged to over 4.2v, in that case most cells would probably explode. Every cheap powertool from stores like Lidl & Aldi and whatever all use garbage Chinese...

Indeed, that is why I recommended buying 2 Chinese made packs and once the cells die after a year or two you can replace them with high quality ones.

I could weld you those packs with Samsung 25R cells. Material cost ist already €110 and then add work, shipping and import duty and you're looking at probably over €200 for 2x 5ah batteries

I said nothing about original, like I said before, buying just the cases is almost as expensive as the batteries with cells in them.

2 Batteries are €53 with shipping. I can buy them right now.
