6S1P 21700 Tabless Drone / EDF Jet Battery Pack - 0.3mm Copper High-Performance

6S1P 21700 Tabless Drone / EDF Jet Battery Pack - 0.3mm Copper High-Performance

This custom-built 6S1P lithium-ion battery pack is assembled in-house by DIY500AMP for drones, EDF jets, RC aircraft, and compact high-power projects where voltage stability, low resistance, and clean construction matter.

This is not a basic 6S1P Li-ion pack. It combines premium high-current tabless 21700 cell options, 0.3mm T2 copper internal construction, and an in-house build focused on serious drone and EDF jet use.

Why This Pack Is Different

• Selectable cell models: choose the model for your capacity and application requirements, and follow its manufacturer operating limits.
• Cell-dependent performance: voltage sag and usable capacity vary with the selected cell, load, temperature, and state of charge.
• 0.3mm T2 copper current path: every pack uses 0.3mm T2 copper internally.
• Built for drones and EDF jets: designed for compact 6S applications where burst power, voltage stability, and weight all matter.
• Built in-house by DIY500AMP: assembled, inspected, and supported from Florida by a battery-focused shop.

Even the lowest-priced version is a premium pack. The 4000mAh options are not budget generic cells; they are high-current tabless 21700 options built with the same 0.3mm copper construction as the higher-capacity versions.

Top premium option: choose LinkData 65P when maximum runtime and premium tabless performance matter most. It gives this compact 6S1P pack approximately 6.5Ah and 140Wh of energy using only six cells.

Compact 3x2 Brick Layout

The pack uses a 3x2 brick layout, giving it the same physical format as a 3S2P style pack while being wired as 6S1P. This is useful when you need 6S voltage in a compact footprint for drone and jet battery bays.

Internal maximum-performance build: every option is built with 0.3mm T2 copper. The thinner 0.2mm copper option was removed so every pack uses the strongest internal current path we offer in this compact format.

Choose Your Cable Gauge

• 10 AWG silicone leads: recommended for maximum current, aggressive throttle, high burst demand, and EDF jet setups.
• 12 AWG silicone leads: lighter and more flexible option for moderate current builds where weight and cable routing matter.

Both cable options use the same 0.3mm copper internal pack construction.

Configuration

• Series / Parallel: 6S1P (6 cells)
• Nominal voltage estimate: 21.6V (using a 3.6V-per-cell calculation; the manufacturer's nominal voltage varies by cell model)
• Full charge voltage: 25.2V
• Discharge protection: Follow the selected cell manufacturer's data sheet and configure suitable BMS or controller protection for the pack. Monitor individual cell-group voltage; pack voltage alone does not establish a safe low-voltage cutoff.
• Layout: 3x2 brick configuration
• Interconnect: 0.3mm T2 copper, professionally spot welded
• Output leads: 10 AWG or 12 AWG silicone wire

Available Cell Options

• EVE 40PL: 4000mAh premium tabless high-current option; strong value for lighter high-power builds.
• Ampace JP40: 4000mAh premium tabless high-current option with excellent voltage stability.
• EVE 50PL: 5000mAh premium tabless high-power option with strong output and runtime.
• TENPOWER 50XG: 5000mAh premium tabless option for aggressive high-current demand.
• Reliance RS50: 5000mAh premium tabless high-output option.
• Ampace JP50P1: 5000mAh premium high-current option with strong load behavior.
• LinkData 55P: 5500mAh hybrid high-capacity/high-current option for extra runtime.
• LinkData 65P: 6500mAh flagship premium option for maximum runtime and high-power capability in this 6-cell format.

Capacity and Energy by Cell Option

• 4000mAh cell options: approximately 4Ah / 86Wh
• 5000mAh cell options: approximately 5Ah / 108Wh
• LinkData 55P: approximately 5.5Ah / 119Wh
• LinkData 65P: approximately 6.5Ah / 140Wh

Actual usable capacity depends on current draw, cutoff voltage, temperature, airflow, and the application. Energy estimates use a 3.6V-per-cell calculation; actual energy varies by cell model and operating conditions.

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 can 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 protected systems. Do not overcharge, over-discharge, short, puncture, crush, expose to water, or expose to excessive heat.

• Not for e-cigarette use
• Use only in properly designed battery systems
• Do not use damaged packs
• Spot weld only; do not solder directly to cells

Use at your own risk. Proper knowledge is required.
