Sur Ron Battery 72V 50Ah – The Mega 72

Description

Our insane Mega 72 – 72V 50Ah Battery – is capable of delivering 300% as much power as the original battery and packs 176% as much energy in a well-contained size. It will definitely lead you to the moon.

This high-end battery is hand-built in France to perfection. We are using A-grade, top of the line Samsung cells able to steadily deliver huge power output while keeping their capacity for years to come. Cyprien and I have been riding our 60 and 72V packs hard in enduro and in MX competitions. We rode them in the snow by -20°C and in the dust by +40°C so rest assured they’ll never let you down.

Our battery is built into a streamlined, robust stainless-steel case, providing best in-class protection against damages, featuring an integrated handle for easy manipulation and a built-in digital screen for hands-on readings.

Range

Everyone wants to know how far their battery will lead them. It depends on many factors: the type of terrain you ride on, the elevation you’re aiming at climbing, rider’s wheight, etc.

Nevertheless, knowing what you usually do with the stock battery, you can double the range as our Mega 72 Battery brings improvements on two levels:

• more capacity measured in Wh (1843Wh stock vs 3600Wh Mega 72),
• more efficient cells that won’t dissipate as much energy into heat when riding hard.

So if you used to ride 40km with your stock pack, you can safely assume you’ll now be riding around 80km. Will your arms resist that long? Although you’ll feel like the autonomy is never ending, the integrated LCD meter allows you to check the battery’s status in both percentages and volts.

Power

The 72V Mega 72 pack was made with high-power controllers in mind (BAC 4000 & 8000, Nucular 24F, Sintech, TORP TC500…) and steadily delivers 17kW of power. Equally at ease on technical enduro singles, challenging tracks or in high speed situations, our 72V pack was made to provide power for as long as you need (or as long as your motor or arms can handle).

The 72V tension increases working efficiency, maintaining your controller and motor at optimal temperatures while allowing for higher motor RPMs. Top speed and torque will definitely depend on both the controller you use and your gearing. But if you ask me: “how fast can it go?” or “how much torque will it provide?”, there’s only one answer: yes.

In addition, our batteries all come equipped with a state of the art bluetooth BMS, enabling direct visualisation of battery temperatures or cells voltages on your phone.

Safety

The programmable BT BMS monitors all of the pack’s parameters: from cells voltages to core temperature, we have fine-tuned everything to get the most out of our architecture in a safely manner. The BMS is in charge of safety and will reduce or cut off current if required. For instance, it would damage the cells charging at freezing temperatures, so the BMS would prevent it until the temperature rises to a safe level.

The 60V vs 72V dilemma

We could debate for hours regarding what’s best between 60V and 72V. Long story short, the 60V battery will allow you to drastically increase the autonomy while retaining full compatibility with both the stock bike’s controller and charger.

On the other hand, although they require specific chargers and controllers, 72V packs allow to deliver even higher power while also boasting an amazing autonomy. A lower voltage battery will need to output more amps to reach the same power as one with a higher voltage. As amperage is what creates heat, at some point you reach the limit over which you’ll be overheating your motor and controller. That’s the very reason why 72V allows for higher power than 60V packs.

The same goes for 60V packs, sure we could optimise them more towards autonomy, but they wouldn’t be able to provide more than 5 or 6kW of power. Some manufacturers optimise their 60V batteries for capacity only while their 72V offering only aims at high power output with inferior energy-density. This is where the misunderstanding comes from.

That being said, all our batteries are top-notch in terms of power and capacity, so whatever your choice, it will rock you!

So, are you a 60V or 72V rider?
