jcussen Posted January 1, 2020 Report Share Posted January 1, 2020 Anyone using one of these to replace your starting batteries? https://www.raneystruckparts.com/maxwell-12-volt-heavy-duty-engine-start-module-ultracapacitor-ultra-31-1800/?gclid=Cj0KCQiAgKzwBRCjARIsABBbFug-3_jZ4Ecsfh_wkoaeXyEe0YYXZuvWfsslPKJY-NpEYYJRZwVA9TMaAmA_EALw_wcB Quote Foretravel 40ft tag 500hp Cummins ISM 1455 watts on the roof, 600 a/h's lithium in the basement.

rickeieio Posted January 1, 2020 Report Share Posted January 1, 2020 These were discussed a couple years ago on the HDT section. I believe there are designed to be used in place of one of the regular battery bank, with the rest of the bank remaining as lead/acid. But, I've slept since then.

Not such a great deal if you stlll have to keep two LA batteries. Quote Foretravel 40ft tag 500hp Cummins ISM 1455 watts on the roof, 600 a/h's lithium in the basement.

rickeieio Posted January 1, 2020 Report Share Posted January 1, 2020 True, but I can see where trucking companies would like them. They're lighter, and can throw a LOT of juice out instantly, so no slow cranking. Hit it and even if it doesn't fire, in a few minutes, it's loaded for another shot. Interestingly, Tesla just bought the largest producer of these. Think of the acceleration possible w/ AWD. Make a pass down the strip and by the time you get back to the line, they're ready for another run.

Scrap Posted January 1, 2020 Report Share Posted January 1, 2020 Maxwell does make the 2 post GSS modules for industrial generators and stuff. These don't have the internal 12V charger so you don't need the battery with it if you don't want to go that way. The one they showed me was hooked to a 120V LaMarche, but I'm sure a 48V input one could be figured out. The caps bleed their power over a day so the charger is going to be a constant suck on the 48V battery, so a guy would probably have to manually manage that.
