6S2P Custom Battery Pack – High Performance 21700 Cells (Multiple Options Available)

6S2P Custom Battery Pack - High Performance 21700 Cells (Multiple Options Available) This 6S2P custom battery pack is built using premium 21700 lithium-ion cells, carefully selected for high-current applications. Each variant uses a different cell type, allowing you to choose the right balance of power, capacity, and budget for your specific build. This is not a generic pack. It is designed for serious performance applications where voltage stability, current delivery, and reliability matter. Recommended options: Ampace JP50P1 or TENPOWER 50XG with 0.3mm copper for maximum performance. Available Cell Options EVE 40PL Reliable and cost-effective Good for moderate to high current builds Ampace JP40 Stronger discharge than typical entry-level cells Better voltage stability under load EVE 50PL High capacity (5000mAh class) Balanced performance and runtime Ampace JP50P1 High power output Lower voltage sag under load TENPOWER 50XG Premium tabless design Extremely low internal resistance Excellent burst and thermal performance Reliance RS50 Premium high-output cell Stable voltage under aggressive load Copper Options (Important) The copper thickness you choose directly affects current handling, resistance, heat, and overall performance of the pack. Copper 0.2mm (High Performance) Excellent balance between performance, weight, and cost Lower resistance than nickel-based builds Suitable for most high-power applications Built using 12 AWG silicone wire leads Copper 0.3mm (Extreme Performance) Maximum current capability with lower resistance Reduced voltage sag under heavy load Improved thermal performance during aggressive bursts Built using 10 AWG silicone wire leads Why the 0.3mm option costs more: Thicker copper material has a higher cost More demanding welding process requiring higher energy Use of specialized copper welding flux to ensure proper weld quality Significantly increases spot welder tip wear, requiring more frequent replacement Additional labor and setup time to ensure consistent and reliable welds If your application involves aggressive throttle, high burst current, or demanding setups such as EDF jets or performance builds, the 0.3mm copper option is recommended. Configuration Series / Parallel: 6S2P (12 cells) Nominal Voltage: 21.6V Full Charge Voltage: 25.2V Cut-off Voltage: 15.0V Capacity: ~10Ah Energy: ~216Wh Performance Continuous: ~80A to 120A Temp Limited: up to ~180A Peak Burst: up to ~300A to 360A Peak Power Example: 25.2V x 300A+ = 7,500W+ Performance depends on cell type, airflow, and cooling.

After Purchase, Please Provide Aircraft model Battery bay dimensions Lead length Connector type Safety Warning for Lithium-Ion Battery Usage Customers should have a clear understanding of lithium-ion battery handling and safety before making a purchase. Lithium-ion batteries are highly sensitive and may pose fire, burn, or explosion risks if improperly handled. Always charge batteries on fire-resistant surfaces, and never leave them charging unattended. By purchasing, you assume full responsibility for any injury, damage, or loss arising from improper use. Only use proper chargers and do not mix batteries. Not for e-cigarette use Risk of fire if misused Use in protected systems only Do not use damaged cells Do not overcharge or over-discharge Do not expose to heat or water Spot weld only, do not solder Use at your own risk. Proper knowledge is required.
