What Defines a High-Performance eBike Battery?

Every battery is built on a few core specifications that determine its behavior:

Higher voltage increases potential motor output. It directly influences how “strong” your system feels.

Indicates how much energy the battery can store. A higher capacity pack will ride longer before needing a recharge.

Voltage × capacity. This is the most realistic measurement of range potential.

Determines how much sustained load the battery can support. Important for high-torque motors.

Inside the A-Series Battery Platform

Built on Samsung 50S cells for maximum stability and efficiency.

The A-Series was engineered from the ground up using Samsung 50S 21700 cells, offering higher capacity and improved discharge characteristics compared to earlier B-Series cells.

A‑Series batteries are built inside a CNC‑machined aluminum housing that protects the cells, improves heat management, and maintains a compact form factor.

• Dual-lock security system.
• Type-C charging port.
• 4A fast charging capability.

A-Series Battery Models

Below is the full breakdown of the A-52, A-52L, and A-65 eBike battery packs.

A-65

The flagship A-Series battery

The A-65 is engineered for riders who need extended range, greater discharge capability, and higher voltage. It is built with Samsung 50S cells and a strong CNC aluminum enclosure.

• 65V (18s4p)
• 1296Wh capacity
• Waterproof tested, drop-tested, cell-aged for long-term stability

• Steep and sustained climbing
• High-torque X1 Pro 4 performance
• Long-distance Photon 2 adventures
• Heavy-duty or loaded riding

Setting Up Your Battery Using X-Series Controllers

Your X-Series controller uses a minimum voltage setting to protect your battery from excessive sag or deep discharge. If improperly configured, performance can drop or the controller may shut down.

How to adjust
your minimum voltage

• Open the Ride Control App.
• Ensure your phone is connected to your eBike wirelessly.
• Navigate to Battery Settings.
• Adjust the minimum voltage based on the recommended values below.
• Save your settings to keep them active.

Setting up your battery's minimum voltage

The key to finding the ideal minimum voltage setting is to match it with your ebike's battery specifications. For example: If your battery has a nominal voltage of 52V, it's recommended to set the minimum voltage in the Ride Control app to around 44V or 45V. This ensures sufficient power and range while protecting your battery's health.
You can set it lower than recommended since your battery's BMS will also have a cut-off voltage programmed into it. We have added this setting for additional protection.
For improved battery life, we encourage you to refer to our recommended cut-off voltages below but please note that this is set up using the 21700 Samsung 50s cells found in our A-series packs. The recommended minimum voltage for the 50s cell is 3.2V.

Samsung 50s cell nominal voltage   3.6V
Recommended minimum voltage settings   3.2V

Please note that the Photon 2 kits are compatible with 52V, if you select a higher battery voltage in the app, you will receive an error of controller over voltage. When looking at batteries, it's important to understand what the specifications can offer you. There's more to it than simply looking at power capabilities.

Summary

The A-Series battery lineup gives riders clear options depending on weight, range, and power needs:

• A-52: Lightweight and efficient
• A-52L: Higher capacity and discharge
• A-65: Maximum voltage, maximum range, maximum durability

Combined with proper voltage setup in your X-Series controller, these batteries form a complete, reliable energy system for your CYC mid-drive.
