6S2P 21700 Tabless Drone / EDF Jet Battery Pack - 0.3mm Copper High-Performance

6S2P 21700 Tabless Drone / EDF Jet Battery Pack - 0.3mm Copper High-PerformanceThis custom-built 6S2P lithium-ion battery pack is assembled in-house by DIY500AMP for drones, EDF jets, RC aircraft, and high-power projects where voltage stability, current delivery, and clean construction matter.This is not a basic Li-ion pack. Many common drone Li-ion packs are built with older non-tabless cells and standard nickel strip construction. This pack is positioned higher: premium high-current 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 Premium tabless cell options: selected for stronger current delivery, lower resistance behavior, and better performance under load. 0.3mm T2 copper current path: every version uses 0.3mm copper internally for maximum current capability. Built for drones and EDF jets: designed for applications where burst power, voltage stability, and pack quality 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 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 performance matter most. In 6S2P format, this option gives approximately 13Ah and 281Wh.Configuration Series / Parallel: 6S2P (12 cells) Nominal voltage: 21.6V Full charge voltage: 25.2V Recommended cut-off voltage: 15.0V Interconnect: 0.3mm T2 copper Output leads: 10 AWG or 12 AWG silicone wire Cell Options and Estimated Energy EVE 40PL / Ampace JP40: about 8Ah / 173Wh EVE 50PL / TENPOWER 50XG / Reliance RS50 / Ampace JP50P1: about 10Ah / 216Wh LinkData 55P: about 11Ah / 238Wh LinkData 65P: about 13Ah / 281Wh - top premium runtime option Cable Gauge 12 AWG: lighter and more flexible. 10 AWG: recommended for higher current demand, aggressive throttle, and EDF jet setups. Actual usable capacity depends on current draw, cutoff voltage, temperature, airflow, and the application.Construction Details Laser-cut T2 pure copper busbars 0.3mm copper selected as the standard internal interconnect Professionally spot welded and inspected by DIY500AMP Built in-house and shipped from Florida, USA Included 6S balance lead 10 AWG or 12 AWG silicone output leads Bare wire output unless a connector is requested Optional Add-OnXT90 or XT150 connector installed: +$5Recommended Applications RC EDF jets High-performance drones High-power RC aircraft Custom high-current 6S applications Production TimeThis is a custom-built battery pack made in-house. Build time depends on order volume, selected cell availability, and connector requirements.Safety Warning for Lithium-Ion Battery UsageLithium-ion battery packs can pose fire, burn, or explosion risks if improperly handled. Always charge on fire-resistant surfaces and never leave charging unattended. Use only proper chargers and protected systems. Do not short, puncture, crush, overcharge, over-discharge, expose to water, or expose to excessive heat. Use at your own risk.
