The A-65 is CYC's most powerful battery. Built for riders who want maximum range and uncompromising output, it packs 1296Wh of energy into a precision CNC aluminum case designed specifically for the X1 Pro Gen 4 and Photon Gen 2. With 20Ah at 65V and a 130A peak discharge BMS, the A-65 is built to match the most demanding motors CYC makes.
Why the A-65 Is Built Different
1296Wh of Capacity
Nearly 2.5x the capacity of the standard A-52. The A-65 is the battery for riders who never want to cut a ride short. Long-distance trails, heavy cargo builds, back-to-back days without a charger — this is what it was made for.
Samsung 50S 21700 Cells — 18s4p
Genuine Samsung 50S cells in an 18-series, 4-parallel configuration deliver 20Ah of high-drain capacity. The same premium cells, scaled up to match a motor that means business.
130A Peak Discharge BMS
The A-65 runs a dual safety BMS with 130A peak discharge — purpose-built to keep up with the X1 Pro Gen 4's 280 N.m of torque and 6kW peak output without flinching. Short-circuit protection, overcharge and over-discharge protection built in.
CNC Aluminum Case
Precision-machined aluminum housing built for impact resistance, weather protection, and heat dissipation. This is not a battery you'll be babying on the trail.
Sideways Slide-In Mounting System
The A-65 uses an innovative sideways slide-in mount — secure, fast, and designed for seamless integration with X1 Pro and Photon Gen 2 frames. No fumbling, no tools, no compromise.
4.5A Fast Charging
Faster charging than the A-52 Series. The included 4.5A charger gets you back on the trail quicker so you spend less time plugged in and more time riding.
Compatibility
The A-65 is designed exclusively for use with the CYC X1 Pro Gen 4 and CYC Photon Gen 2. It is not compatible with other CYC kits. If you are unsure whether the A-65 is right for your build, reach out before ordering — we are happy to help.

Frequently Asked Questions
Is the A-65 compatible with all CYC kits?
No — the A-65 is designed exclusively for the X1 Pro Gen 4 and Photon Gen 2. It is not compatible with other CYC systems. If you are unsure, reach out and we will confirm compatibility for your build.
Does it come with a charger?
Yes — the A-65 includes a 4.5A fast charger with a standard 3-prong plug.
How does the mounting system work?
The A-65 uses an innovative sideways slide-in system — the battery slides in from the side of the frame rather than from the top or bottom. It is fast, secure, and designed specifically for the X1 Pro and Photon Gen 2 frame integration.
How does the A-65 compare to the A-52 Series?
The A-65 operates at 65V (vs 52V), carries nearly 2.5x the capacity (1296Wh vs 520-780Wh), and features a higher-rated 130A BMS. It is a purpose-built high-output battery for CYC's most powerful kits. The A-52 Series is the right choice for builds where the A-65 is not required.
Is this available in Canada?
Yes — Power in Motion is Canada's premier authorized CYC distributor. You're buying from a dedicated CYC specialist with full warranty support.
