The question was about a tractor battery, which if it's truly a tractor battery would mean it's deep cycle similar to a golf cart, marine or RV type. Tractor batteries are designed to be drawn down in use and not expected to float with the alternator keeping it topped up like an automotive SLI...

These are handy for situations like this.

Keep up the fight, Don Quixano. You're right about a lot of but seems to me what makes luddites luddites isn't specifically this technology or that but the pervasive evolution of society and the demands it places upon itself, real or perceived. IOW, the role simple air cooled vehicles played...

The way you've indicated with your arrows is the preferred multiple battery connection for charging. It's incidentally equally or more important during discharging to wire them this way if it's a full time bank. Although for trickle charging it's not going to be as critical since the...

I've always kind of thought relying on them in an accident to hold a shovel was marginal. Certainly not a Hi-Lift. Even a relatively low speed crash will exert several tens of G, so a 30 lbs jack rapidly becomes equivalent to quarter or half a ton.

I just picked up a Noco GEN5X1, their waterproof on-board single supply charger. Not sure if it's the same for all Noco models but the force mode on this one will supply it's full current (5 amps in my case) but only for 5 minutes before dropping back to its controlled profile (which does step...

Totally agree, things are made to be used. You do your best to maintain and protect but use them regardless! FWIW Dyneema has good UV resistance. It'll bleach but that's not directly indicative of the fibers weakening. It's of course not as resistant to the Sun as steel but then again it...

Does Delrin have a sufficiently high melt temperature to be used as a hawse?

Rollers can be used with synthetic. The concern is the rope can work itself into the corners where the vertical rollers overlap the horizontal ones if you direct the line too far off the center into the corners. They use rollers on ships and for industrial applications with synthetic after...

This assumes the solar controller doesn't regulate voltage at all during bulk. That might or might not be true. It's a likely assumption that most PWM solar controllers will try full duty cycle to get Isc, though there's also reason to assume a designer might implement an max voltage, perhaps...

A power supply doesn't have the same characteristics as a solar panel. These are just hasty example ideal sources, both being theoretical 85W sources. The power supply in this case would be rated 14V@6A. The solar panel would be Isc=6.5A, Voc=17.1V and MPP=13.91V@6.2A. Notice how a power...

Both PWM and MPPT solar controllers may or may not work with a power supply feeding them. Success stems from the assumption that the solar panel is current limited and that eventually a rise or fall in current has relationship to voltage fall or rise so the controller know it has found the...

Leaving the solar controller in the circuit would solve any chemistry question since presumably it would matched. You can feed a solar controller with a power supply (e.g. a 120V converter, alternator, etc) but it's somewhat redundant unless you need it to buck down for gel and doesn't let you...

This seems like a good find (they have 'em on eTrailer, which increases confidence I'd think). Haven't found any spec for it so I'd hesitate using with a gel type without checking first. But probably work great for other lead acid types.

You're not crazy. Is the battery a gel (like for a UPS or something) or a maintenance-free SLA/AGM type? If it's not a gel type your vehicle already has a charging system that you could almost just plug it into the cigarette lighter but you'd want to current limit, both to safely charge and to...

Why swap in a 4BT for a 6.5L Detroit? They weigh almost the exact same and you lose HP and torque. I doubt it's going to use less fuel or be any more comfortable to drive. Plus you gotta use 2 more quarts of oil each change! It doesn't look like the current owner was building it for...

Imagine the howls if he said lifter instead of follower on an overhead cam engine though!

Good point. The 4WD Sunrader had the same rear axle uniqueness with a 6x7.25 bolt pattern where the front (like rest of us) use 6x5.5 wheels. I think the wheels are typical of Isuzu NPR or Hino trucks but is pretty unusual domestically otherwise.

From what I've seen the term was or is used to market what are sometimes solar, sometimes grid-tied batteries to people who have back-up generators. Not everyone who has a generator understands the finer points and it's easier for a salesman to explain it. But if you've gone through a black...
