Aloha, I'm trying to restore power while also trying not to rush into anything. Hoping someone could help. I've got food thawing. I'm trying to connect 8 Trojan L16 Batteries to create 12v.
Background Details
I'm trying to upgrade my system as my former batteries dropped too low and caused my GoWise (1500/3000w) inverter to stop making power (fuses are good). So I found some used Trojan L16s batteries and put my old AIMS (1000w 12v) backup inverter back into service. The built in charger on the AIMS is no longer working. A PoWMr 60amp MPPT is charging the batteries with 4 (440w) panels. I first setup two independent 12v banks with 4 Trojans each and that worked. Now I'm trying to connect those two battery banks together. I got a spark while making the last connection. So I stopped to seek help as I understand I'm dealing with plenty of stored energy in these batteries.
Question
Can I wire the batteries as shown in the diagram? Is it okay to make the final connection even if it produces a spark when they touch?
