Smarter | Smaller | Lighter | Better

Ready for Late December

There is no comparison. The smallest and lightest 16.4kWh of battery power you can get and it is built in Canada. Complete customization and bulk/dealer pricing available so please contact us! Royer Mini 48V 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 and RB Smart LCD. Royer use LiFePO4 chemistry which is some of the longest lasting and safest lithium chemistries. You can always monitor real-time usage from the built-in RB Smart LCD or from the Phone/tablet app.


Using 16 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) Mini 48V 320Ah battery replaces the usable energy of over 27 standard golf cart (6V 225Ahr) batteries!

Cycle Life

If Royer batteries are 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 (13.12kWh) 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 their 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. Royer cases are easily accessed to diagnose/replace parts after the warranty ensuring you are never left with a paper weight. For reference: A cycle is a full charge and discharge; if half of the capacity is used and then charged backed up, it’s a 1/2 cycle.

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 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 Royer 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.


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 250A continuously, 300A 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.


The most important aspect to 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. Royer Mini series batteries have an optional rolling & mount cart that can provide the ability to move the batteries and to be use as a stand.

Size/Weight (29.5″ x 17.7″ x 10.4″ 286lbs)

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 foldable handles. Royer batteries should not be exposed to direct water at anytime.

Series/Parallel (1S/4P)

Royer Batteries Mini 48V 320Ah is not made for series and up to 4 paralleled batteries. Royer rolling stand is made to hold 3 batteries maximum.
