10S8P Battery Pack 36v 33600mAh 33.6Ah

Introducing the TORQUEBOARDS 10S8P Battery Pack, the largest and highest-capacity option in our 10S battery series. Designed for riders who demand maximum power and endurance, this pack offers an impressive 8P configuration for unmatched range and reliability.

With its high-voltage 10S configuration, it delivers enhanced efficiency, smoother acceleration, and reduced heat generation compared to lower-voltage 6S systems, making it ideal for high-performance electric skateboards and compact electric vehicles.

As the sibling to the 12S8P battery pack, it offers similar endurance in a more compact form factor, providing a perfect balance of size, capacity, and performance for serious riders.

Engineered for Maximum Power

This battery pack is capable of delivering up to 180 amps, providing outstanding power for your electric skateboard or electric vehicle. Thanks to the Modular Bypass BMS, the full amp output of the pack is accessible, ensuring high performance capability.

We recommend a peak current of 160 amps for short bursts. For higher current demands, it is essential to reinforce and upgrade parallel and series connections, main power wires, and connectors to improve conductivity and manage heat effectively. Exceeding 160 amps requires the use of larger gauge wires and high-capacity connectors to safely handle the load and reduce the risk of overheating.

For safe and reliable operation, maintaining a continuous current below 80 amps is advised.

21700 Molicel P42A Battery Cell Discharge Rating

The 21700 Molicel P42A battery cell is rated for a maximum continuous discharge of 45A per cell in parallel, but the duration it can sustain this current depends on various factors, including:

• Parallel Configuration: The total discharge capacity increases with more cells in parallel.
• Voltage Drop: High current draws cause voltage to drop, impacting performance.
• Heat Management: Effective cooling is required to prevent overheating during high discharge rates.
• Cutoff Voltage: Discharge ends when the voltage reaches a predefined safe limit.

In real-world scenarios, pulling the full rated amperage continuously is unlikely, as it would quickly drain the battery and generate excessive heat.

Realistic Average Amperage During Riding

• Light Riding (Flat Terrain, Moderate Speed) - Ideal for cruising on flat surfaces at low to moderate speeds. 10–20A
• Aggressive Riding (Hills, High Speed, Acceleration) - High-current demands during acceleration, hill climbing, or high-speed rides. 30–60A
• Peak Amperage (Full Throttle, High Loads) - Short-term loads during full-throttle acceleration or heavy loads. Sustaining this level for extended periods can lead to overheating and rapid battery depletion. 70–100A or more, depending on the battery pack, motor, and ESC specifications.

Crafted with Quality and Precision

Built in-house in the USA using 21700 Molicel P42A cells, this pack offers high capacity and high discharge capability. The modular bypass BMS supports charging up to 10A, allowing high amp discharge during use and cell balancing for enhanced safety, longevity and performance. We recommend using a 2A or 5A charger as your standard charging solution to consistently maintain and prolong the lifespan of your battery pack.

Built and Assembled in the USA

All of our battery packs are meticulously assembled, spot-welded, and finished in-house at our facility in Dallas, TX. We take pride in producing high-quality battery packs at competitive prices, utilizing the best battery cells available. Recognizing the critical importance of battery safety, we manage the entire production process to maintain the highest standards. Additionally, we provide comprehensive safety guides and tutorials to help you better understand and safely work with your battery pack.

Modular, Plug-and-Play Design

Our battery packs are thoughtfully engineered with modularity in mind, making maintenance and repairs straightforward. If any component malfunctions, it can be easily replaced without requiring soldering. Refer to our detailed battery tutorials for step-by-step instructions.

Key Replaceable Components:

• Battery Management System (BMS): Plug-and-play for easy replacement.
• Anti-Spark Switch: Modular and simple to swap.
• Charging Port Fuse: Quickly replaceable for safety and convenience.
• Charging Port: Designed for seamless replacement.
• Battery Voltage Display: Easily replaceable to keep your pack performing at its best.

Modular Battery Cell Modules

Battery cell modules are designed to be replaceable, allowing for easy maintenance or upgrades. If a module becomes faulty or malfunctions, it can be replaced by unsoldering the two power wires and the balance wire, installing a new module, and then re-soldering the connections. While this process is intended for those with prior experience in soldering and electronics, it is manageable with the right tools and skills.

Replacement battery cell modules are available for purchase to ensure seamless repairs and maintenance. Detailed instructions and support are also provided for advanced users.

Why We Don’t Use Battery PCB Boards

We avoid using battery PCB boards because once a module is soldered to the board, removing or replacing it becomes significantly more difficult, often requiring the entire battery pack to be rebuilt. Our approach focuses on maximizing the lifespan and usability of individual components to provide greater flexibility and longevity.
