HCL-HP 14.8V (4S) 6400mAh 150C LCG Hardcase w/XT90

Get true 4S power in a compact 3S footprint with the SMC Racing HCL-HP LCG Hardcase.

If you're tired of strapping top-heavy brick packs into your rig that ruin your handling, the SMC Racing High Cycle Life - High Performance (HCL-HP) series is exactly what you need. SMC engineered this Low Center of Gravity (LCG) hardcase to sit at just 37mm tall, meaning you get massive 14.8V punch and 6400mAh of runtime in a case the exact same size as a typical 3S battery. It is the ultimate drop-in upgrade for 1/8 scale buggies, truggies, and hardcore bashers where weight distribution and body clearance are critical. Fits V1 & V2 Traxxas Maxx

Inside the hardcase, SMC is using premium 100% LCO cathodes. In track terms, that translates to incredibly low internal resistance (IR). The lower the IR, the faster the energy flows to your ESC, resulting in explosive bottom-end torque, insane top speeds, and a battery that runs significantly cooler under heavy amp loads compared to budget packs.

Why You'll Love It

• LCG Footprint: At a slim 37mm tall and weighing only 514g, it drastically lowers your chassis' center of gravity for razor-sharp cornering and reduces the dreaded traction roll.
• Massive 150C Discharge: Engineered to eliminate voltage sag under load, giving you instant throttle response and sustained high-RPM power when you need to clear massive gaps.
• Premium LCO Chemistry: Built with 100% LCO cathodes for optimal performance and a high cycle life, ensuring you get consistent, reliable punch bash after bash.

What's In The Box

• (1) SMC Racing HCL-HP 14.8V 6400mAh 150C LCG Hardcase LiPo Battery

Note: Requires a dedicated, balance-capable LiPo charger and a fire-safe LiPo charging bag or box.

Pro-Tip: While this pack can safely handle up to a 5C charge rate in a pinch, we always recommend balance charging at 1C (6.4 Amps). Charging at a steady 1C keeps the individual cells perfectly balanced and significantly increases the overall lifespan and performance of your premium SMC pack! Also, always double-check that your ESC and motor are rated for 4S power before pulling the trigger.
