There is no comparison. The smallest and lightest 2.18kWh of battery power you can get and it is built in Canada. Complete customization and bulk/dealer pricing available so please contact us! Royer's Nano 12V 170Ah battery uses a smarter BTBMS which lets you know what’s going on at all times as well as controls the automatic built-in heating. Royer Batteries use LiFePO4 chemistry which is some of the longest lasting and safest lithium chemistries. You can always monitor real-time usage from the optional RB Smart LCD or from the Phone/tablet app.

Capacity

Using four of Royer's high capacity 3.2V 170Ah prismatic cells translates into a more reliable battery with less parts and less issues. Royer Batteries cells are designed to use full depth of discharge giving maximum capacity when required. You always have the option (through Bluetooth App or from factory) to change the charging and discharging parameters to a 20%-90% cycle to further extend the lifetime of the battery. Compared to lead acid, lithium offers more than 2x the usable power per rated Ah due to depth of discharge. To put it in perspective, just one (1) Nano 12V 170Ah battery replaces the usable energy of over 3 (3.2) standard golf cart batteries (6V 225Ahr).

Cycle Life

A cycle is the complete charge and discharge of the battery. For example: If half of the capacity is used and then charged backed up, its 1/2 cycle. If the battery was cycled daily, it will be 8-13 years until you realize 20% capacity loss. This means with the 170Ah, after 3000 – 5000 cycles you would still have up to 136Ah (1.09kWh) of usable power left. The battery can easily have a useful life of more than 10,000 cycles or 25 years in most applications. Since Royer batteries are so long lasting they include Royer's 10-year warranty, although you can expect it to run much longer. Royer can fully service the battery at any point in its lifetime, under warranty or after. Their cases are easily accessed to diagnose/replace parts after the warranty ensuring you are never left with a paper weight.

Smart BMS

Lithium batteries require a battery management system to ensure proper voltage and temperature cut-offs. Separating Royer batteries from other lithium batteries is their smart BTBMS. It allows users to set parameters of charging and discharging, monitor real time usage, see available power left, and turn on & off the battery from a phone/tablet. Since you’re able to turn off the battery with one click, you can more safely install, transport and turn off your system. Royer's optional RB Smart LCD screen also shows BTBMS values and allows turning off either charge or discharge of the battery. The BTBMS has automatic high/low temperature & voltage cut-offs to maximize your battery life. Since the BMS they use is open source, there are many different apps that can monitor the battery & Royer BTBMS can be purchased in the marketplace easily for after warranty repair.

Temperature

With LiFePO4 chemistry, normally it cannot be charged in 0 °C or discharged in -20 °C temperatures. Royer batteries come with a built-in automatic heating that raises the internal temperature above 5 °C when charging. Regardless of your battery location and climate, your battery will work. If the battery charging is turned off via the app or hard switch, the heater is turned off. Without a charging source, the heating is also turned off. The heater will only use power from the charging source.

Amp Rates

Royer smart BTBMS is rated to output 150A continuously, 200A 60S, 300A 1S, with an instant 1120A short circuit cut-out. Charging cut-off is peak 125A for 60s. Recommended charging is 50-75A per battery for longest lifetime of the battery. Multiply amperage rates by the number of paralleled batteries to increase ratings. Please gauge and fuse your wiring accordingly to account for expected loads.

Safety

The most important aspect to all Royer batteries is safety. LiFePO4 is one of the safest lithium chemistries and will not catch on fire like other li-ion batteries. There is no venting or required maintenance with these batteries. Storage losses are under 3% per month so you can leave the battery dormant for long periods without issues. Royer BTBMS has internal cut-offs for shorting and too high of loads but always fuse your systems as if these features are not in place. Best practice is when the battery is off to treat it as live.

Size/Weight(7.9″ x 8.8″ x 11.9″ 40lbs)

There is no lighter or smaller battery per kWh. Royer batteries are made using the smallest size case possible. The lead acid equivalent would be 6x heavier and larger. Most other lithium batteries are 20-50% heavier and larger footprint. This battery can be oriented however you need to fit in your battery space. On these batteries they use a thick metal casing with removable handles. Royer batteries should not be exposed to direct water at anytime.

Series/Parallel (4S/4P)

Royer Micro 12V 320Ah is capable of up to 2 series and 4 paralleled batteries. For 48V systems, 4x series 12V or 2x series 24V configurations are identical performance so it is up to personal preference which makes the most sense. Royer batteries are cross compatible between different Ah versions and ages (voltage must match). For example, start with a Nano 12V 170Ah and add a Micro 12V 320Ah anytime later.

He Acted Like He Didn’t Care… Now He Wears It Everywhere
Color: Gold Steel
I bought this watch for my husband for Christmas (his birthday is right before), and he loved it! At first, he acted like he didn’t care, but now he wears it all the time—whether he’s dressing up or just going out. It really completes his look. It was a little big at first, but we had it adjusted and now it fits perfectly. Overall, it’s a very nice, stylish watch. Very happy with this purchase!

Can't beat this price and quality!
Color: Silver/Gold
This is my first Amazon review, and I must say how impressed and happy I am with this watch! I've owned this same exact watch before, but sadly I lost it last year. I was reluctant to pay the full original price of $275, so I decided to chance it with Amazon, and I couldn't be happier with my choice. Having owned this exact model before, I feel very confident I can spot a real vs. fake MK watch. It met almost all the criteria to determine that it's real. Here are the positives and negatives: Criteria to determine authenticity: - Model number (MK-8344) matches original and is included on the back of the dial - The Michael Kors logo is featured on the dial. - The font of the letters is consistent with the official brand logo - The spacing is even, and that the quality of finish is high. - Came in original Michael Kors box where one edge is broader than the other, with a clear writing of ‘Michael Kors’ on it. - The lid was wider and bigger than the box, covering a major portion of it, meaning it's authentic. - The Michael Kors logo is included on the top of the box in fine and clear text. - The box has a batch stamp located on the bottom. - “All Stainless Steel” at the top in a semicircular pattern along with the model number. - Original MK logo embossed on the crown - Has three sub-dials with three different number values (a fake MK watch will have subdials that showcase the same values.) - Displays date with a proper alignment inside the window (in a fake watch, the display is disputable and unaligned) Negatives: - No warranty booklet included. - No extra link included Although it didn't meet every expectation, you still can't beat the quality and price. A part of me thinks that most of the 1-2 star reviews are from people who have a vested interest in seeing you pay full price, so they leave negative comments to scare you into going to Macy's or MK directly. Don't let them fool you. This watch appears to be genuine, and even if it's not, it's the best damn fake I've ever seen.

LOVE LOVE LOVE
Color: Gold Steel, Color: Gold Steel
My husband - the one to the right. Has had this for about 4 years now. I'm coming to write a review because the battery just went out and I'm wanting to repair It for him for this Father's Day trip. As I'm looking in the nooks & crannies I'm noticing that I purchased this back in 2019/2020 something like that - (can't go back and check or I'll lose this message ) BUT IT LOOKS GOOD! Yes It is needing a good wash, and I seen on YouTube a reg toothbrush and dawn soap will help with that. But wow this looks great after all this time. I'll post a pic of what It looks like now. He only wears It when he's dressed, he doesn't wear It daily but here is what It looks like with no cleaning whatsoever
