13S4P 21700 Battery Cell Holder / Tray

by DIY500AMP.COM

This is a 13S4P battery cell holder designed for 21700 lithium-ion cells.48V E-Bike ApplicationThis 13S4P configuration is ideal for a 48V e-bike battery pack. A 13-series lithium-ion setup provides a nominal voltage of approximately 48.1V and reaches 54.6V when fully charged, which matches standard 48V e-bike controllers and chargers.Using 4 cells in parallel increases current capability, reduces voltage sag under load, and helps keep cell temperatures lower during acceleration and sustained riding. This makes the tray well suited for mid-drive and hub motor e-bike systems.The tray keeps cells properly aligned during battery pack assembly, helping with consistent spacing, clean spot welding, and overall pack stability.Features:Designed specifically for 21700 cellsSupports 13S4P configurationClean alignment for nickel or copper busbarsIdeal for DIY battery packs, e-bikes, power tools, and energy storage projectsPrinting notes:Print with PETG, ABS, or ASA for heat resistancePLA can be used for mockups or low-temperature applicationsNo supports requiredImportant: This model is a mechanical holder only. Proper battery safety knowledge is required when building lithium-ion battery packs.Design by DIY500AMP.COM
