Smarter | Smaller | Lighter | Better

There is no comparison. The smallest and lightest 8.2kWh of battery power you can get and it is built in Canada. Complete customization and bulk/dealer pricing available so please contact us! Royer Micro 24V 320Ah 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. We 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 eight of Royer high capacity 3.2V 320Ah prismatic cells translates into a more reliable battery with less parts and less issues. Royer 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) Micro 24V 320Ah battery replaces the usable energy of over thirteen (13.6) 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 320Ah, after 3000 – 5000 cycles you would still have up to 256Ah (6.56kWh) 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 we include their 10-year warranty, although you can expect it to run much longer. We can fully service the battery at any point in its lifetime, under warranty or after. Our 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. Our 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 we 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 200A continuously, 250A 60s, 440A 1S, with an instant 1120A short circuit cut-out. Charging cut-off is peak 200A for 60s. Recommended charging is 50-100A 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 (24.4″ x 7.7″ x 12″ 126lbs)

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 (2S/4P)

Royer Batteries Micro 24V 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 24V 170Ah and add a Micro 24V 320Ah anytime later.

Buy it
If you're looking for a comfortable thick and nice turtle neck this is the one. It's nice and form fitting nice weight to it to keep you warm. But not to thick that you cant just wear it on a regular sunny day if you wanted. The design pattern Is also very nice. Can dress it up or down. I bought the black and then immediately bought the rust orange color for my friend once he tried on mine he wanted one immediately so I gifted him one. He loves it. Definitely worth the buy. Excellent quality. I bought a Large 5"11 165lbs

A true turtleneck that retains a snug high neck.
Color: White, Size: X-Large
I've found this brand to have gotten better over the years as far as offering the American market what it needs in terms of realistic sizing. I only wish they'd realize that there are a lot of us who are long in the back and arms where my only choice is to go a size up and sacrifice a slim fit for sleeves that are long enough plus a back that doesn't go up past my waist just because I reach up for something, that and I like to be warm. So these are such nice quality turtlenecks that it's hard to complain about but maybe the company will read this. The snug neck stays up is plus number one since that's why I'm buying a full neck. They come with very nice weaves in the fabric, good enough for casual or formal wear. Finally the warmth you seek is there but I've worn them in what most would think isn't the right temp for a turtleneck. Also they have them in white! Yes, a lot of others just don't for reasons I can't fathom, and the pic you're seeing is accurate, these will form to your shape without being ridiculously thin material. Several washes later and they are as fine a garment as when I first wore them. I've only found one other brand that compares to these but it's much more expensive, COOFANDY is affordable in these times of expensive everything. Warm but also a lightweight shirt, I've gotten them really dirty with actual dirt and it washes out so well you'd never know it. Don't let my taking off one star stop you, try one yourself and you'll be coming back for more.
