3S1P 21700 Tabless Drone / EDF Jet Battery Pack - 0.2mm / 0.3mm Copper Options

3S1P 21700 Tabless Drone / EDF Jet Battery Pack - 0.2mm / 0.3mm Copper OptionsThis custom-built 3S1P lithium-ion battery pack is assembled in-house by DIY500AMP for drones, EDF jets, RC aircraft, receiver systems, and compact high-power projects where low resistance and clean construction matter.This is not a basic Li-ion pack. Every option uses premium 21700 cells, selected 0.2 mm or 0.3 mm T2 copper internal construction, and an in-house build focused on serious RC and drone use.Why This Pack Is Different Selectable cell models: choose the model for your capacity and application requirements, and follow its manufacturer operating limits. Selectable copper current path: 0.2 mm or 0.3 mm T2 copper, as selected in Copper and Cable Gauge. Built in-house in Florida: assembled, inspected, and supported by DIY500AMP. Configuration Series / Parallel: 3S1P (3 cells) Physical layout: Flat single row of three cells (1 × 3). Nominal voltage estimate: 10.8V (using a 3.6V-per-cell calculation; the manufacturer's nominal voltage varies by cell model) Full charge voltage: 12.6V 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. Interconnect: selected 0.2 mm or 0.3 mm T2 copper Output leads: 10 AWG or 12 AWG silicone wire Cell Options and Estimated Energy EVE 40PL / Ampace JP40: about 4Ah / 43Wh EVE 50PL / TENPOWER 50XG / Reliance RS50 / Ampace JP50P1: about 5Ah / 54Wh LinkData 55P: about 5.5Ah / 59Wh LinkData 65P: about 6.5Ah / 70Wh - top premium runtime option Cable Gauge 12 AWG: lighter and more flexible. 10 AWG: recommended for higher current demand and aggressive throttle. Actual usable capacity depends on current draw, temperature, airflow, and cutoff voltage. Energy estimates use a 3.6V-per-cell calculation; actual energy varies by cell model and operating conditions.Production TimeThis is a custom-built pack. Build time depends on order volume, selected cell availability, and connector requirements.Safety WarningLithium-ion battery packs require proper handling, charging, storage, and protection. Do not short, puncture, crush, overcharge, over-discharge, expose to water, or expose to excessive heat. Use only with proper chargers and properly designed systems. Use at your own risk.
