I have (4) CALB 3.2V 200AH cells connected to make a 12.8V battery, Terminal connections are with copper pipe I flattened and drilled. The cables to the inverter are 1/0 welding wire. During a 120 AH event I noticed a burning smell and then smoke coming from one of the terminals. The wires were very hot to the touch. This battery has been in use about 30 months in my travel trailer with no noticeable problems. I have removed the battery to my garage workbench and want to do some testing. How do I re-create the large amp draw that caused the smoking without using my 3000 watt Magnum inverter? Is there a bench test device that is capable of performing this test. Visually the cells look good, with no swelling, or discoloration on the terminals. Each cell is reading 3.33 Volts. Oh, the BMS is a Daly 12V 80 amp.
