Power That Performs: Diamond C Battery Options & Upgrades

Published March 26, 2026

When it comes to hydraulic systems, winches, and power units, your trailer is only as reliable as the battery behind it. At Diamond C, we don’t settle for industry standard — we engineer for performance, longevity, and real-world reliability.

That’s why we’re excited to introduce our new Lithium Battery Upgrade, along with an upgraded NOCO charging system — delivering smarter, longer-lasting power across our trailer lineup.

Standard Power — Already Above Industry Norm

All Diamond C trailers equipped with power units come standard with a Continental Group 27 Series battery.

Why Group 27?

Because the industry typically uses a smaller Group 24 battery, but we believe your trailer deserves more. A Group 27 battery provides:

Deeper reserve capacity
More available cycles
Stronger performance under load

Right from the lot, you’re starting with more power than most competitors offer.

NEW: Lithium Battery Upgrade Now Available

For customers who demand even more performance, we now offer an optional Lithium Battery Upgrade for trailers utilizing a Group 27 battery.

Available on:
✔ Dump Trailers
✔ Tilt Trailers
✔ Hydraulic Dovetails
✔ Hydraulic Jacks
✔ Winch-Equipped Models

This upgrade is designed for heavy-use applications and customers who expect maximum reliability.

Why Upgrade to Lithium?

– 300% Increase in Battery Cycles

Lithium technology delivers dramatically longer battery life compared to traditional lead-acid options. That means fewer replacements and lower long-term ownership costs.

– 3-Year Warranty

Built with confidence — and backed accordingly.

– Reduced Static Discharge

Lithium significantly minimizes power loss when the trailer sits idle. Your trailer is ready when you are.

– Master On/Off Switch

Integrated control allows for easier shutdown during storage, safer operation, and improved battery management.

Cleaner. Smarter. More Reliable Power.

Whether you’re running a dump trailer daily, operating hydraulic equipment on the jobsite, or relying on your winch in demanding conditions, lithium delivers a more consistent and dependable power experience.

It’s not just an upgrade — it’s a long-term performance solution.

Now Standard: NOCO 110V Charger

To further improve charging performance and reliability, all Diamond C trailers equipped with a 110V charger will now come standard with a NOCO charger.

NOCO is known for:

Intelligent charging technology
Improved battery health management
Enhanced safety protections
Reliable, maintenance-friendly operation

This ensures your battery — whether standard or lithium — is charged efficiently and protected from overcharging or damage.

Still Need a Heavy-Duty Lead-Acid Option?

We also continue to offer our Crown 27HDC Battery Upgrade for customers who prefer a premium lead-acid solution.

This 12-volt battery delivers:

130 Ah at 100 hours
95 Ah at 5 hours
Operational range from -40°F to 120°F

Built for extreme environments and high-demand applications, the 27HDC remains a strong upgrade option.

The Diamond C Difference

Power systems may not always be the first thing customers ask about — but they’re one of the first things they rely on.

From standard Group 27 batteries to advanced lithium upgrades and intelligent NOCO charging systems, Diamond C continues to invest in smarter, longer-lasting solutions that work as hard as your trailer does.

Because when it comes to performance, reliability, and long-term value — details matter.
