Awesome rig! I love it! Total composites box? Do you have the original A0 alternator (Niehoff N1506) still in place? I believe the original alternator is rated 100 Amps total for 24V and 12V sides combined. Which isn't a lot, so 17 Amp DC to DC charger is a prudent choice. Are you using an...

Thank you, excellent point about lithium being 14.4V. I got the lead crystal figures from the manufacturer's documentation, but now that I am looking at them, I realized that I made a mistake and 4x 180 Amp-hr batteries are going to be 9.2Kw-hr. So, my actual price per kw is 11 cents before...

I am contemplating "Lead crystal" vs. building a battery bank out of LF280K prismatic LiFePO4 cells. I can get 4 Lead crystal batteries (12V 180 Amp hr each) for a grand. That's 360 Amp hr at 24volts, or 18.4 Kilowatt hours, if I got my math right. My mini split supposedly draws 750 watt per...

I read more on the UK site of Sterling and their AB24100/24200 is not recommended for lithium, because the device does not limit current. Which is unfortunate if the battery bank can consume more than the alternator can produce. I am wondering if I can rig a current limiting device, and whether...

I would be careful with how much I draw from the alternator on the 24 volt side. I would build in a healthy safety margin. While the alternator may be rated for peak 140 amps, it is not designed to put out that amperage for hours. It can do that for short periods, but if you force it to put out...

I found the following options for 24V to DC battery chargers: Victron buck-boost 50 amp DC to DC converter $672 Sterling power 35 Amp DC to DC converter, for charging LiFePO4 batteries: https://www.sterling-power-usa.com/SterlingPower24volt-to-24volt-dc-to-dc-batterytobatterycharger.aspx...

Last year's pic. Since then the frame got extended in the back to make towing possible. The tank got upgraded to a larger one from M939 (without the PTO notch) and the cab was insulated with dynamat and painted from the inside. I have air ride Bostrom seats in the cab. I'll post more pics in a...

I have a 17 ft Winnebago mounted on the back of the M1083 instead of the bed. Used spring mount, just like tanker trucks. I need to build a battery bank to run the AC. I have a 24 volt military diesel generator for charging them. I looked into FeLiPO4 (Lithium Iron phosphate) and so called "Lead...
