That's what he meant, you have to connect them all together with heavy cables regardless but since the BMS can communicate with each other they may be smart enough to know they are in series or parallel and adapt their profile.

What do you think is using these batteries? They seem pretty large to fit inside anything so I assumed they came from ambulances, powered wheel chairs or something like that.

Have you swept that antenna @dreadlocks to verify their bandwidth claims? I know Comet and Diamond do some interesting stuff so I don't necessarily disbelieve but 30MHz 2:1 bandwidth on 70cm for a dual-band antenna with a claimed gain of 6.2 dBi is pretty dang wide. That's not too much worse...

What I've found is a ~50 A-hr stationary gets me a couple of days on my Engel MT45 using a 50 watt panel and an MPPT controller with typical Colorado summer weather, e.g. hot, low humidity and good sun interrupted by afternoon (losing good solar but reducing fridge load) clouds and storms...

From what I know about critical applications the reason for a scheduled replacement period is that it's assumed the user will neglect something to the point of considering worst case as typical. So with a battery you may have to assume it was routinely run flat and timely charging forgotten...

Wow, you do have a lot of D-STAR repeaters. https://www.repeaterbook.com/repeaters/location_search.php?state_id=51&type=city&loc=Tysons%20Corner

It's the lowest end battery, yup it's a starter (and judging by the weight this particular group 35 must be intended to turn over lawn mowers normally). It's not really possible to find a true deep cycle in group 35. There's really no market for something like that with just 50 to 65 A-hr. I...

I have a battery like you're describing. Put a set of military terminals and Powerpole & fuse pigtail on the cheapest Walmart 1-year POS I could find locally. It was I think about $85 including the $30 core charge since I didn't have one to trade. I grabbed it as a place holder while I was...

It became plainly obvious the day we moved out of Denver why it's not wise using things like your current QTH or truck brand or model as a forum name. It hasn't been true for almost 8 years now.

That is cool! Bear in mind I live in Grand Junction so it's not a high traffic area and I'm working through one of three digipeaters and one of two Igates. So collisions are actually very uncommon (like >90% packet success on first try) but range and aspect between stations can be, especially...

Made a few changes in the APRS station @dreadlocks. Went from the Argent T3-301 to this TT4/SD125V2 combo. I have never been fully satisfied with how hot the T3-301 settles to in this application. The case on them is a simple folded sheet steel instead of die cast aluminum that is more...

Need a higher legal GVWR maybe?

It's a variation on a very old cartoon that as near as I can tell no one has ever claimed or figured out to whom to attribute it. It has been redrawn by Jim Massara, N2EST, of Hamtoon (http://hamtoons.net) fame. Federico Abdolcadir seems to be the artist for the one Victron used...

Watching for silent key estate sales is always a way to find old gear but please be nice and don't try to take advantage of a widow who knows nothing about radios and make reasonably fair offers. FWIW, the rate of growth in FCC license issues seems to be pacing slightly faster than the growth...

It can be a pretty significant legal issue if you have to kill a four legged critter, especially if they are a protected species. Imagine the media firestorm of someone protecting him or herself from a grizzly in Yellowstone. Even if it's not endangered a prosecutor might try to charge you...

That's the question. An intact 'Nest in shape this good would sell at $1600 pretty easily but having been made 1st gen 4Runner specific it's just such a limited market now. Selling the whole truck would be easier. I'd be interested in the whole thing but the 'Nest alone means I have to then...

Dual VFOs cost money. The FTM-100 isn't strictly a dual VFO radio but it pushes the dual watch feature to almost be as good. It's a good radio without a doubt but if I was buying a non-digital mode radio right now it would be a TM-D710 or TM-V71. I know Yaesu is selling a fair number of...

Awesome job! Hey yeah, IFS mini trucks can do the Rubicon! Dual cases or at least 4.7 t-case gears are mandatory and there are a few pieces of critical armor. Although I will admit I'm glad I did it and don't have to again. Next time I'll ride shotgun and actually see the place.

It wouldn't be legal to do a straight VIN "reassignment" but if you started with a Jeep frame and a title and swapped everything over it might be possible. There might be a path using a kit or custom car rule, which I think I've read about here in Colorado getting a new VIN assigned. How...
