I am thinking of building my first battery. I will use Molicel p42a.
I need your help on the following:
What BMS should I choose ? charge only or discharge as well. How many amps ? Brand ? Any links appreciated (especially from EU)
Which spot welder to buy ? I want something cheap since it is going to be used only for one battery, and also if there is a version to plug it in the wall socket instead of having to buy extra batteries. I will be using 0.2mm nickels. Also links if possible
I need the battery to charge fast, so if you can suggest some good chargers. Links also !!
If possible to give me links either from EU stores or from banggood or aliexpress
Kweld and Malectrics are very good, but not cheap. The Flipsky spot welder is decent from what I hear. You could try that out. The Kweld has a capacitor bank that you can plug into the wall but it’s more money. Sunkko plug into the wall but take a lot of power and can have reliability issues. Probably would recommend trying to borrow one or buy a battery from someone
YZ power on Aliexpress has great chargers for decent prices. I only use their chargers, don’t really know who else sells them. You can find that on Aliexpress by searching for the YZPower store.
