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.

Features:

  • Secure Bluetooth connection
  • Harnesses, Thermistors, and NMEA 2000 kit included
  • Monitors the state of charge
  • Can turn your engine into a dedicated generator with generator mode
  • Pre-set battery libraries

Excellent choice
I will skeptical when buying these because I have a pitbull bulldog that likes to chew holes in every toy. This is her favorite she choose on the ball, but she doesn’t actually ruin it because she can’t. It holds up one of the squeakers broke, but that’s expected I guess my wife actually ordered more. I’m not sure if it was from the same seller or not but those ones they don’t favor as much for some reason I seen the same different colors. My dog even sleeps with it sometimes. The picture shows for sleeping with it. I’m definitely happy. I got these. They are tough. I like the fact that they have those little recessed holes so they can grab a hold of it and not get it all slimy like the other balls we have.

Durable and a must have for aggressive chewers
Color: Blue+Red
These are without a doubt the best toys that I have ever purchased for my dog. He's an aggressive chewer and quickly destroys almost every toy I buy. This one hasn't been destroyed yet and the squeaker is still working at about 5 months.

GSD Winner
Color: Blue+Red
10/10 recommend for big dogs with a tough chew. Our GSD absolutely loves these squeaky balls. They have perfect texture for his teeth and for our grip. They are the size of a baseball and are so durable and fun. Yes the squeaky is LOUD but he loves them so much that it's cute

If your dog loves tennis balls, you NEED these
Color: Azure+Orange, Color: Azure+Orange
Raising any puppy is tough. Raising a German Shepherd puppy has often left me questioning my life choices. So I was ecstatic the day that my 60-lb puppy decided that he loves tennis balls and occupied himself for 2 hours without needing constant intervention. Naturally, my immediate response was to make sure we had a constant supply of large tennis balls for dogs available. Now my puppy loves mischief, but he’s not an aggressive chewer. And I was irritated to discover that every brand and size of tennis ball broke within an hour max of play. By simply playing fetch and batting the ball around with his paws, every single tennis ball split into 2 halves. We needed something better! These squeaky balls are exactly that! They come in a 2-pack. I gave my pup the 1st one a week ago and it’s still going strong! We play fetch in the backyard, he brings it into the doggy pool with him, it rolls around in the dirt and can be rinsed off easily. It’s by far his favorite toy, and he takes it everywhere with him. Finally a squeaky ball that can keep up with my dog! These are the perfect size, texture, bounce, squeak, everything. These are the ONLY squeaky balls I will buy from now on. Five stars for sure!
