If you want to spec a system you should have the electrical knowledge of where to put fuses and wire the batteries so that no cable in the system goes over its rating and use the proper fuses in the right place. Things like that are taught to you at university and almost any competent electrical engineer worth his salt will know what to do. In the electrical industry no knowledge is same, but a little bit is a very dangerous thing because you don't know what you don't know. Just because it works doesn't mean it is right.

I'm out of the country so sadly I can't. Or I would. 

there was a thread about it somewhere, the consensus though seemed to be that it has no actual benefit though. I will try find it and paste it if i do.

here is one thread, but it isnt the one i was thinking of: https://powerforum.co.za/topic/3219-mecer-sol-i-ax-5-m-doesnt-work-with-pylontech/ 

@seant Thank you very much for the advise.
I just have to wait for all the toys to arrive.
I will keep this thread updated.
 

@Nicom, I would suggest literally visiting any business that recycles, collects old computers (laptops). Cash in hand has proved a real motivator I have personally found. In my case I was sold the batteries per kilogram will little option on what batteries I took! So far I have collected 1400 old 18650 batteries and have only began sorting through the lot.
