Zeus High-Energy Alternator Regulator

ARCO’s Zeus is the only high-energy external alternator regulator to feature Bluetooth and a native app (on IOS and Android) allowing for easy installation and configuration. With its intuitive interface, you can access information on your system that you never had before. This information will enable you to regulate your system and optimize your battery charge and alternator output, resulting in a safer experience while protecting your energy system investment.

Zeus is the only alternator regulator that can read 2 shunts at a time (the battery shunt and alternator shunt). This feature enables Zeus to react to inputs from the battery current/temperature and alternator current/temperature.

Through the ARCO Zeus application, you are in good hands. Your data is automatically logged and can be shared with your technician to troubleshoot your system remotely. You can even import your remote technician’s configurations. 

Zeus optimizes battery charges for 12-48 volt systems. Whether you are using Lithium (LiFePo4) batteries or lead-acid Deep Cycle batteries, Zeus has you covered with its pre-set battery libraries and configurable menus to optimize your charging profiles. Zeus manages a complex set of inputs by giving you easy-to-understand options.

Zeus also takes into consideration the power of your engine and allows you to configure the alternator’s power take-off from the engine by managing the field, or duty. An advanced feature of Zeus is that it can turn your engine into a dedicated generator with the press of a button, whereby it focuses the alternator’s performance on the creation of energy to replenish your battery bank quickly.

Consistent with Zeus’ ease of use, Zeus is the only alternator regulator on the market that comes with alternator/battery harnesses and 2 thermistor harnesses, without an additional charge, saving users money and time from sourcing harnesses.

  • Secure Bluetooth co
  • nnection

❤️
Size: 32W x 34L, Color: Light Stonewash
These Wrangler work jeans have been a solid choice for everyday work. They’re comfortable enough to wear all day while still feeling tough and durable for job site use. The material holds up well through bending, kneeling, and regular wear without feeling too stiff or restrictive once broken in. They fit true to size and allow good movement, especially when working in different positions. The pockets are practical for tools and everyday items, and the overall build feels sturdy and reliable for work conditions. Overall, they’re dependable work jeans that balance comfort and durability well, making them a good go-to option for everyday hard use.

Elastic waist

Love these jeans. They fit well and are accurate in size. I especially love the stretch waist as I sometimes go up or down in wait by a few pounds.

Overall good quality for the price.
Size: 48W x 32L, Color: Carbon
Overall I’ve been happy with these jeans. They have a tight fit when washed and putting them on but loosen up shortly after wearing them. I’m in between sizes so 46 fits snug and 48 basically falls to my ankle if I didn’t have a belt after they loosen up. Most pairs have lasted me 1-1.5 years roughly before they all seem to tear at the crotch area, front thigh areas or near belt loops wear i grab to pull them up. I primarily have 5-6 pairs for work and use them once a week with regular washing once a week. I do a lot of walking and squatting for work and am regularly exposed to water. Occasionally I do get a pair that tear in the crotch area within a month or two but for the most part can expect 1-1.5 years before replacing. I would purchase again considering cost and average use i get out of them.

Perfect Fit, Durable, and Stylish!
Size: 44W x 32L, Color: Smoke
⭐️⭐️⭐️⭐️⭐️ Perfect Fit, Durable, and Stylish! I’ve been wearing Wrangler jeans for years, and they never disappoint. The fit is spot-on—comfortable around the waist and hips, with just the right amount of room through the legs. The denim feels tough and durable, yet soft enough for all-day wear. What I really like is how versatile they are. I can wear them to work, out in the yard, or even on a casual night out. They hold their shape after multiple washes and don’t fade like cheaper brands. The stitching is solid, and the pockets are deep enough to actually hold a phone or wallet without feeling bulky. Overall, Wrangler jeans deliver quality, comfort, and value. If you’re looking for jeans that can handle real-life wear while still looking sharp, these are the ones. Highly recommend!
