52V vs. 48V battery Packs - FAQ
52V systems have been used by DIY and e-bike hot-rodders to achieve higher performance from their e-bikes. We have quietly designed the necessary infrastructure to make a turn-key 52V e-bike possible.
The RipCurrent S is the first production e-bike to offer a 52V performance option.
The 52V battery pack uses a 14S configuration vs. the 13S configuration which is used for the 48V e-bikes. The industry has settled on the 48V system which is an artifact of the 12V lead acid battery infrastructure. Modern e-bikes almost all use lithium-based battery packs and do not really need to have voltages in the 12V increments.
Most battery packs found on the market are designed for the 10S or 13S configuration. To achieve the 14S setup, we needed to design our own packs to properly accommodate the added cells. Additionally all of the other parts of the bike needed to be upgraded to handle the increased voltage and power.
Another requirement for our design was that our 48V and 52V packs can be interchangeable and backwards compatible to avoid leaving customers stranded with obsolete e-bikes. All of our e-bikes produced now can take advantage of the 52V revolution.
What is the difference between the 48V and 52V RipCurrent S?
The ONLY difference between the bikes is the battery pack. The batteries are interchangeable and the controller is designed to properly handle both 48V and 52V pack voltages.
What is the point of having 52V battery?
E-bikes have evolved from 24V to 36V, then 48V and now we have reached 52V. Basically the higher voltage will let you get more performance out of your e-bike. The battery can be a little more efficient as you can use less current to produce the same amount of power, but the main point is overall better performance.
When this higher performance is combined with a larger pack capacity and the latest charging techniques, we can achieve surprisingly high cycle life while maintaining very satisfying performance.
Can we use even higher pack voltages?
Not likely. The 52V pack when fully charged is 58.8V. This is just under the 60 Volt limit at which point the electronics system will be classified as “High Voltage” and there will be a much stricter set of regulations needed to certify the e-bike.
Will I feel the difference between the 52V battery and the 48V battery?
Yes! The bike will be noticeably faster and have better acceleration. Also as the pack discharges, you will notice less decrease in performance.
Can I upgrade to a 52V battery later?
Yes, you can upgrade to the 52V battery in the future. However you will have to get the 52V charger.
Can the 52V battery be used with the 48V bike?
Yes, the 52V packs are designed to be interchangeable with our 48V bikes with LCD display (CrossCurrent S and RipCurrent S). The design of these bikes started with the intention to use the 52V system. The motor, controller, LED lights, and software have the capability to handle the higher voltage.
Can the 48V charger work with the 52V battery pack?
No, you must use a 52V battery charger to charge a 52V pack. The charging voltage is higher for the 52V pack and are not interchangeable.
Can your 52V bike work with the 48V battery pack?
Yes, the 48V battery pack can work with the bike that is sold with the 52V battery pack. This is handy if you already have one of our e-bikes.
How is it possible to get 1,500 charge cycles out of the 52V pack?
Every charge or discharge action reduces the batteries capacity by a small amount. When the battery pack decreases down to 70% of its original capacity, we classify the pack to have reached the end of life although the pack can still function.
Typically this point is reached when the pack goes through 500-800 full charge cycles. There are however ways to increase the number of cycles before the pack reaches the 70% level. This involves doing the following techniques:
Avoiding charging the battery above 80% capacity
Avoiding discharging below 20% of capacity
Reducing charge rate
Storing the battery at 50% when there is long periods of inactivity
Discharge the pack below the packs C-Rating.
Our 52V systems can accomplish all of these methods through the use of the onboard software and the use of the a special programmable charger.
What is the weight of the 52V pack vs. 48V pack?
The 48V battery pack is 11.0 lbs
The 52V battery is 12.0 lbs
