Here is the voltage, I tried to smooth out some of the noise, but this about as good as its going to get. Discharge was at about 140A. Charge was at 110A. Here is the tail end of the charge cycle. The discontinuity in the middle is when my laptop went to sleep for a bit.

Did a full discharge test. Called it done at 520AH. Looks like all 560AH are available, but I going a bit conservative. I will post up a graph when I have a chance. Tested the alternator charging and control. For the naysayers about "alternator meltdowns", I had my alternator pegged at...

Sounds like you might need a progressive spring, but from what I gather its not common on ford trucks.

Well, I did qualify with the sky limit... But yeah, not cheap. A set of 2.5s with adjusters would set you back around $2,500. You could sell your current shocks to recoup some of the cash hopefully. I am also not sure what modifications your chassis would need to use a coilover. I am sure...

I got a weak cell fault when testing, so I checked the BMS internal resistance measurements for the first time. They were pretty varied, with one cell over 1mohm, and others near 0.5mohm. I should be seeing around 0.2 max (at mid range SOC, discharge), and about 0.12 nominal. Though it will vary...

If the sky is the limit, I would do coilovers. A good shop should be able to dial in a spring rate and valve package pretty close on the first go. Just need sprung/unsprung weights, travel, ride height, and desired usage.

A few notes as I wind down the testing. The Orion BMS requires some cell taps to be attached to a specific cell when not in use. Failing to do so can cause the ASIC which reads cell voltages to pick up noise, creating a random fault code, which made me think the BMS was failing. The Jr 2 also...

Galley is installed, though I need to finish the water and electrical connections. Should be pretty easy. IMG_20200903_115825689 IMG_20200907_094331629 Ended up directional sanding the top, and using a clear urethane. IMG_20200902_162427165 IMG_20200907_123548150 b I am slowly filling...

Galley is painted, and electrical/plumbing have been fitted, I will get some photos up tomorrow. I have the main plumbing runs for the drains worked out. Just need to make a bracket to support the drain valve and camlock for the hose. Planning forward to rebuild the hydronic system, and...

Looks like CCA, explains the meltdown.

If you jumper cables bypass the shunt, your meter won't see the charge current.

Are they pure copper, or copper clad aluminum? I have seen some pretty sketchy "2awg" no name jumper cables.

Radiant emissions from a body in the 90F range are pretty minor, and you aren't fully surounding yourself with this cool surface anyways. Heat transfer will still be dominated by convection and conduction from the skin. So you will still have heat transfer to your environment via...

Stopping condensation is not possible when the dew point is above the comfortable temperature (anywhere its hot and humid). The main advantage of cooling the air, is that you are also lowering the humidity. As humans sweat to cool themselves, this improves comfort even at a higher temperature...

I was just able to cram the current sensor into the box. An interesting note about the current and voltage measurements from the BMS. The raw values are not software filtered. They vary significantly when running from the inverter, or charging from a mains charger. For example my AC unit...

Battery pack has been commissioned and is working fine. I will do a capacity test later this week, and setup the alternator charging. Gray tank i installed, and awaiting plumbing. I insulated where possible, but may add some more down the road. I may change the filler wire next time...

The USA is a signatory of the international motoring treaty. With a tourist visa you can temporarily import a vehicle you own for up to 1 year in the USA. As far as customs is concerned, is that the vehicle is legally registered in your home country. LHD/RHD, headlights, mirrors, air bags...

I got torque setup on my phone, and an OBDII to bluetooth adapter connected to the BMS. I roughed out a few gauges for the various critical PIDs. Looks like I can get all the important data. Even better, with Torque pro, I can log data directly to my phone for later review. The BMS also...

Your correct, the Orion Jr gives me full control over balancing. Right now it set to balance when any cell is over 3.25V, and bring all cells within 5mv. It will do this regardless of charge/discharge. Since my rig will be occupied full time, time above 3.4Vpc is very minor. I may go with a...

Finally got the cells balanced at 3.575V plus/mins 2mv. I shouldn't need to do that again thankfully.
