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

Amazing exfoliating toner
Size: 4 Fl Oz
I am almost 40 and have had acne since puberty. I have tried so many products. The products that showed some improvement (like Proactiv) changed the texture of my face. Literally made my face feel like a basketball. I’ve tried some products that I’ll notice an improvement after a week or so, and the it would just stop working. I have never used something that so drastically helped my face in such a short amount of time. Notably, within 5 days my blemishes were almost gone. Within a week, my chin felt smooth instead of feeling the bumps of every clogged pore. The discoloration of my face, such as the redness, hasn’t totally disappeared, but it is improving. My face doesn’t feel oily throughout the day. My skin feels tighter, like I got a facelift. Moisturizer along with this product is important. And it is important to follow the directions and start slowly with this product. Use it every other day for the first week, gradually working your way up to daily and then twice a day. It is a shock to your skin and can dry it out if you go overboard. But for what I needed this product for, it has exceeded my expectations in every way. I couldn’t recommend it more. Just a heads up, it is applied like a toner. I expected a face wash, but it is a liquid that you apply to cotton and rub on your face. I wash with CeraVe SA cleanser, follow it with this, and apply whatever moisturizer you prefer—I’ve been using moisturizer with SPF so as to not damage my skin more than I already have.

PRODUCT WORKS GREAT IF USED CONSISTENLTY!
Size: 4 Fl Oz
Paula's Choice Liquid Exfoliant does exactly what it states. After applying the liquid product to my face with a cotton pad, it deeply cleansed the pores and exfoliated the top layer of dead skin cells without the harsh granular feel of most other exfoliants. It is important to continue using it regularly for the best results because, initially, the exfoliated skin was dry and flaky. Using a washcloth helped remove the flaky skin, followed by a moisturizer. After continued use, there was no more flaky skin. It was replaced with a smoother, more evenly toned skin tone. REMEBER TO USE A LOT OF SUNSCREEN AND TO REAPPLY IT THROUGHOUT THE DAY!

WORTH THE HYPE!
Size: 4 Fl Oz
I’ve been using the Paula’s Choice 2% BHA Liquid Exfoliant for a couple of months now, and I can honestly understand why this product has such a loyal following. I mainly bought it to help with the appearance of my pores and blackheads, and I’ve definitely noticed a visible difference since adding it into my routine. When I first started using it, I did notice a slight tingly feeling on my skin. It didn’t hurt or cause any actual irritation, but it definitely startled me a little at first 😭 Thankfully, it never turned into redness, burning, or discomfort, and my skin adjusted pretty quickly after the first few uses. I currently use it around 3–4 times a week… or at least I try to, when I remember. Even with me not being perfectly consistent, I’ve still noticed that my pores look smaller and cleaner overall, especially around my nose where I tend to get the most blackheads. My skin texture also feels smoother, and my face just looks a little clearer and more refined in general. I also appreciate that it’s fragrance-free because my skin can be pretty sensitive at times. The formula feels lightweight and easy to apply, and it layers well with the rest of my skincare products without feeling greasy or heavy. One thing I’d recommend is easing into it slowly if you’re new to chemical exfoliants, especially if you have sensitive skin. Starting with 1-2 uses a week worked really well for me. Overall, I’m really happy with this product and definitely plan on continuing to use it. If enlarged pores or stubborn blackheads are something you struggle with, this is genuinely worth trying.

Game changer for clearer skin
Size: 1 Fl Oz
I’ve been using this consistently and it has really helped improve my skin texture and keep pores clearer over time. The formula feels lightweight like a liquid toner and absorbs quickly without leaving any sticky residue. The quality feels very high and well formulated, especially with the salicylic acid working deep in the pores to help with congestion and breakouts. It also feels gentle when used correctly, and I haven’t experienced irritation. In terms of value for money, a little goes a long way so the bottle lasts a long time even with regular use, which makes it worth the price. The fit into my routine is easy since it layers well with other skincare products, and the overall appearance of my skin looks smoother and more even with continued use. Overall, great quality, effective ingredients, good value for money, and a staple in my skincare routine.

Noticeable improvement in skin tone and texture after consistent use. Love this product!
Size: 4 Fl Oz
I have been using this product for almost two months now. It is easy to apply, feels nice, I but was unsure about adding it to my long term skin routine. Now, after two months, the noticeable changes and clearing in my blemishes, sun spots and pores has convinced me it will be on the regular, long term routine. I use it twice a day and have no problems with dryness at all. And to be honest, I don't think it took that long for the changes to appear but they were subtle and I just started noticing my make up went on better and my skin had a "glow" it didn't have before. I noticed some reviews commenting on the price but I find it to be extremely reasonably priced for the size and even after two months, I have plenty left to last another two months.
