Yes, connectivity will resume once the battery is in 4G cellular network coverage. It will function just fine without coverage. Yes sir. The battery pack comes with a bi-directional USB-C PD 3.0 capable of charging your laptop at 100W.

These are 5.2Ah 21700-cells from Tier-1 manufacturers like Samsung, LG, and Panasonic.

Folks. Thank you! We are doing several tests for fitment, enclosure design, electrical design, mechanical architecture, etc. Here is a picture from last month comparing a 3D printed case to Reention DP5-21700 that can house a 1kWh pack. We have now reduced the size and improved the charging...

I had a technical discussion with @scrambler and showed him some of the core technology we are developing for batteries and how it will improve safety, performance, and longevity. Without getting into some confidential design details, if you could share some thoughts here, @scrambler , that...

We can actually set the charge current just from the cloud portal, and the BMS will signal the charger to change the current. We have just begun working with a charger manufacturer to implement this. You can change anywhere from 1A to 20A. The BMS is designed for 50A peak and can handle 30A all...

That colorful piece that you see is a door for the charge port. It houses an ultra-fast 20A charge port like the one shown below. The door also acts as a shield to protect the discharge port at the bottom. We have looked at sideways option as well and currenlty we have integrated ABUS lock into...

IP 68. 2 hours - submerged in water at 1m depth. No problem!

Thanks for your comments. Although the length is a bit longer than a regular DP5 case, it offers the most advanced BMS for E-bikes and an extreme level of safety. Most shark/Dolphin packs were never designed with automotive-grade engineering in mind. We look forward to serving the E-bike community.

That's definitely on the map. Thanks for sharing that thought. We want to integrate our API with Alexa and Apple Smart Home suite. This requires extensive work on embedded systems, which we will initiate after our launch. Our immediate goal is to offer the safest and longest-lasting packs to the...

It has a 4G SIM card (in the future, we are planning to use e-SIM). You could use any network, such as AT&T, T-Mobile, or Verizon. If there is no network, BMS has a 32GB micro-sd card that can store the data up to 5 years without any loss and whenever it connects to the system via USB cable or...

Thermal runaway has several signatures that can be picked up 30 minutes before. Typically, the cell starts overheating before crossing a certain threshold. Whenever we notice abnormal voltage and current fluctuations, the algorithms immediately shut down the pack, isolating cells. If, for some...

It comes with an accelerometer and if someone moves the bike or battery, the detection sensor immediately springs into action and alerts the owner.

Nope. You would be able to track the battery, and this feature makes it difficult to steal the bike. Moreover, the amount of insight you can get from telematics is fantastic. We could handle about 1 million data points per device per hour. So, this provides accurate control over the state of...

At the moment, we are only looking at 52V. Not at the moment, they will be available Q-1 2025, and they will be UL-2271 certified and come with built-in 4G telematics and GPS and a suite of advanced safety features.

Our new 52V, 20Ah battery design would provide an excellent alternative for Hailong, Dolphin, Shark / DP-5 from Hailong, and other cases normally found on DIY E-bikes. People in the DIY world deserve a well-engineered battery pack. I am curious to hear from EBR readers about the color scheme...

Our new battery in 2025 will have Tabless cell and can be charged at 1C and still get 2000 cycles. The problem is there are not many chargers that can charge at 20A. Our pack will handle 10A charging all day long.

It has been a dream for a few years and has taken a lot of work, but finally, we are super excited to announce our Micromobility Battery Factory. I am sharing a sneak peek for Zen customers on EBR. I have been silent here for the past few weeks because we are busy setting up our battery...

This is totally normal. A bit of fiber frayed at the edges is normal, and this is from small rocks and chips. Gates belt typically lasts about 8000 to 10,000 km, depending on the power level used and maintenance interval. It would help wash the belt with a simple (NON-pressure) washer-like...

We think people ultimately benefit from a longer life than a longer range. Even at 80%, the bike offers more range (~90 to 100 km) than what people are used to riding in one go. So, we prioritized long-life and it defaults to long-life mode each time. This is also the reason why we are able to...

Correct. To change the charge limit to 100%, the CAN signal needs to come from the controller via the display. Without this CAN signal, the BMS will not be able to switch the charge modes. We wanted to implement it so that it can also be changed when the battery is off the bike, but that would...
