For sure if you need start batteries then you need them.
I was just suggesting in lieu of a "jump pack" get your house batteries in order so you can A. not damage your $1500 bank and B. jump yourself if if needed.

12.2v is 50% DOD/SOC, 11.61 is 10% so at 10.xx volts they are deeply discharged. Lead acid batts aren't a fan of that.
Ah I see.

Yes I always try to stay above 50% SOC. Something fishy was up as my meter was still showing 75-80ish percent (I dont remember the exact number at this point) but the voltage had tanked over night. It was saying I had only pulled ~130Ah out. I did idle the truck, and it was charging at 20ish amps, but maybe that screwed things up meter wise?

I will do the start/voltage test on the batteries this week if I can get the kid to help me start the truck :D


Played ski cabin all weekend.


Snow did not suck.

That really kicks ass, no way my family is down for that but I'd love it.

???? how does the Wilson booster antenna work down there on the hood?
I bought the cheap one with the little magnetic antenna, can't tell it does anything...
My buddies have the big Wilson and they work great but I didn't want the antenna 4' in the air like they have them.

Kiddo has skied since she was 2.5 years old, she doesn't have a choice not to come :D

Uhhhh its only down there because I broke it off on some tree branches..... And it seems you can't get parts from Wilson, only a whole new antenna kit (with spring now.... ) for like $70. I have not wanted to spend the $$ yet.

Yes the big OTR antenna works much better than the little mag mount. I have both. But you should look at a directional, they are supposed to be even better, but take some set up/aiming.

This is the road that claimed the antenna. At least just the CF tube broke I guess. I got tight....

Yeah I can see the problem LOL.


Any thought about a Victron Smart Battery Protect to keep the bank from crashing?
I am thinking I am going to put one on my system so I can have some dumbass insurance...
Yes and no. My BMV already has an alarm in it, I just needed to set it to something other than 10v....

I dont know if there was a dead cell, or a frozen batt, but it did crash quick. There isn't much load at night, just the heater occasionally, which it turns out cant ignite the glow plug enough at ~10.5V.....

What a nutty weekend. Headed out late on Friday, with a big storm coming in.

Did not make it very far.... Highway closed. Tree fell and a car hit it. But they cleared in about an hour.


Made it to the pass as it was nuking snow. Parked finally.


Get up early! We got 4th chair Sat and 6th Sunday. Line gets big!


It didn't stop snowing..... This was Sunday 7am


So much snow!!



And then this..... Pass closed in all directions. I guess we are spending another night..... At least we have a nice spot to sleep, unlike the employees.... WSDOT did take a group down Eastbound, but quite a few slept in the lodge.


We moved to a different spot, and got a bunch more snow. This was Monday morning now. Luckily I just had to shovel the windshield and hood, and was able to pull right out of that spot. 4x4 low FTW! Waited for a couple hours in the morning, hoping they would open the road, but after talking to a truck that had run the West side it wasn't happening. Trees down, lots more threatening to fall. A car hit by a tree. Semi truck out of gas, no power, no gas. They did open East, so we started the long trip home.... Big loop with two more passes, but it was the only real option. Pass is still closed.


Stopped to shovel the roof off. The truck felt REALLY heavy with that up there.



Made it home finally. Truck is filthy from all the road grime.... Long trip, but great skiing!

Glad to see this build with the height mentioned. I'd totally take my bus through the woods just like that once I have all three axles set up for steering. And your snow pics still make me wanna get out of rural CO to go play so hard.

It was a fun challenging afternoon on that road. Had to turn 180 degrees around at one point....


How do you get to be plugged in at the slopes? That sounds perfect.
Stevens pass has an "RV Lot" they charge, but have hook ups. Its pretty slick. Pretty much as close as you can park to the main area, and can ski right back to the truck through the woods above the lot.

Ok batteries are real tired.....

Pulled 101ah out. Was sitting at 12.2v with minimal load, and dropped to 11.9 anytime a decent load (heater or fridge) was applied.

Victron gauge is funky. 101ah pulled out, but was saying 86% bank left? I only have 500ah total.

does the gauge need to be calibrated to total bank capacity in order to be accurate?
Yes, you manually tell it how much capacity there is.

I need to adjust it to the aged batteries I guess. Looks like I have about 200ah total now.

Depending on how deep you are wanting to go (AGM is not recommended below 50%) gives you your actual possible usage capacity, in your case maximum 250AH. If you are using high current loads over 10 amps the capacity is reduced further due to Peukert's law.

I have heard the Victron BMV and others don't account for Peukert effects as well as we might hope so a .00 decimal reading volt gauge and a SOC chart is a better gauge of charge.

How accurate is the gauge in the switch panel compared to the BMV?
The similar unit I put in my wifes SXS is .2v high.

Shunt is rated at .4% accuracy for amperage, so not perfect to begin with.

The BMV does take Peukert effects into account. Its using 1.25 at the exponent for lead acid batteries.

I didn't even think to check the voltage on the Victron.... :rolleyes:

I did find some interesting tidbits in the manual. This could be why the percentage was so wonky last time, The little bit of charging from running the truck or a little solar probably reset it.

Battery Musings..... Why can mfg's stick to regular sizes.

Same dimensions basically, but more amps and $$ with FR.
Trojan 105AGM, 217AH $916 avail locally.
Fullriver 250-6 250AH (what I have now) $1469 shipped
Lifeline GPL-4CT, 220AH, $1463, avail locally.

These are 2.3" longer, I may not have the room for them....
Victron BAT406225084, 240AH $1047 avail locally

That is thinking of sticking with 6V's. Any other's I should look at?
