Do you want a new smart charger to maximize battery life?

[cyberpika]

Hi guys,

We’re a Boston-based startup founded by MIT alumni, focusing on creating innovative, smart, user-friendly charging solutions for e-bikes/scooters.

Most e-bike chargers push batteries to 100% every time — which is known to shorten battery lifespan and waste energy.

We are launching a new smart charger with adjustable charging modes to protect battery health. You can look at the details of the product here: https://www.cyberpika.com/pages/cyberpika-smart-ebike-charger.

This Smart Charger is designed based on "80/20" EV charging rule with four charging modes:

● 20% (Shipping Mode): Safe battery level for transport and shipping.
● 50% (Storage Mode): Ideal for seasonal riders. Optimal charge level for long-term storage.
● 80% (Default - Daily Ride Mode): The optimal “everyday sweet spot” for maximum battery longevity.
● 100% (Adventure Mode): Full power for long trips and extended rides.

This Smart Charger also comes with 3A fast charging and is 30% smaller than regular charger, which potentially can cut charging time by half and makes it very travel-friendly.

This Smart Charger will fit for 36v, 48v and 52v batteries. It will come with a standard DC barrel (5.5mm × 2.1mm) plus multiple adapters for DC (5.5mm × 2.5mm), XLR, and Junlei 3-Pins.

Whether you look for a spare charger or want to upgrade your current one, this could be your next charger!

Let us know if you have any comments or thoughts!

Thanks,

That is interesting to see a charger that can charge to less than full to help extend the life of the battery. In your example of charge times you seem to have a batter that is smaller in size than typical emtb batteries use. Do you have an example of something in the range of 800 Wh 36v 22 Ah. And could I ask what the "C" rating is for your fast charger.

That is a great idea!
How are you going to deal with all the widely varying charger plugs? What plans to deal with the various voltage, frequency and current combinations around the globe?

The manufacturer of my 625 W-hr battery claims "Lightweight and portable battery charger and it offers rapid charging":

Quick charge from half to 80% in 1 hour​

Charge from empty to 80% in 2.5 hours​

Go from empty to fully charged in 4.5 hours​

Spec:

Input 100-240V, 1.9 – 0.9A​

Output 42V, 4.4 – 6.0A​

My house voltage is 240V, 50Hz and the battery charges quickly from half to full. I have never timed it but I believe it to be about 90 mins for my 625 W-hr battery. The charger and battery are original equipment and are both almost 4 and a half years old and still operating perfectly.

Thanks for the reply. Yeah, we calculated it based on a regular ebike with 15 Ah batteries and 2A charging. For large 22 Ah batteries, it is about 0.14C. Slow but quite gentle on the battery.

Great question! This is quite a complex space. The initial launch will have standard plugs (DC, XLR, Junlei 3-pins) for 36v, 48v, 52v batteries with one 3A output. We are hoping to follow up with more compatible connectors very soon. The adjustable current feature is also on the roadmap next year.

Thanks for the update, I charge overnight so slow charging is my preference.

I have been doing this for years for batteries of varying voltages and choosing to apply a bespoke charging current using an inexpensive CCCV bench power supply. For those with a larger budget, the Satiator has been around for years, and the Mean Well NPB-450-NFC seems to be styled to compete with the Satiator.

However the attraction of the Cyberpika may be that it looks like it will be more affordable than all the above options.

This is actually a cool product. I may pick one up.
