Pylontech Battery Terminal Covers US2000/3000/5000

Description (German)

Terminal Protection Caps for Pylontech US Series (US2000 / US3000 / US3000C / US5000)

I designed these protection caps to reliably cover the battery terminals of Pylontech modules while allowing clear color assignment for positive and negative terminals.
The caps fit snugly but can be removed at any time without tools.

The set consists of two caps:

• red cap with black positive marking
• black cap with red negative marking

This allows the poles to be quickly and clearly identified even in poor lighting or confined installations.

The caps are simply pushed on and held securely in any position by integrated snap features – even upside down.

Compatibility

Suitable for the following models:

• Pylontech US2000
• Pylontech US3000
• Pylontech US3000C
• Pylontech US5000

The model was tested on a US3000C module.

Features

• secure covering of battery terminals
• protection against unintentional contact and short circuit
• easy assembly without tools
• firm fit due to snap-on tabs
• removable at any time
• color coding for quick pole identification
• no supports required
• very easy to print

Print Settings (tested)

Printer:

• Bambu Lab H2D

Recommended settings:

• Layer height: 0.16 mm
• Nozzle: 0.4 mm
• Supports: not required
• Brim / Skirt / Raft: not required
• Print material: PLA

The fit is designed so that the caps sit snugly yet can be easily removed.
Adequate tolerances have been taken into account.

Material Notice (important)

Suitable materials:

• PLA
• PETG
• ASA
• ABS
• PA

Do not use:

CF filaments (carbon fiber)

These can be electrically conductive depending on their composition and are therefore unsuitable for applications near battery terminals.

Safety Notice

Use at your own risk.
These caps do not replace proper electrical installation and serve solely as mechanical protection and covering of the terminals.

Terminal Protection Caps for Pylontech US Series (US2000 / US3000 / US3000C / US5000)

I designed these caps to safely cover the battery terminals of Pylontech modules while providing a clear visual distinction between positive and negative terminals.
They snap firmly into place but can still be removed easily without tools.

The set includes two caps:

• red cap with black positive marking
• black cap with red negative marking

This color coding makes polarity identification quick and reliable, even in low light or tight installations.

The caps simply push onto the terminals and are held securely by integrated snap features.
They stay in place in any orientation.

Compatibility

Fits the following models:

• Pylontech US2000
• Pylontech US3000
• Pylontech US3000C
• Pylontech US5000

Tested on a US3000C battery module.

Features

• protects battery terminals
• reduces risk of accidental contact or short circuit
• tool-free installation
• secure snap fit
• removable at any time
• clear color coding for polarity
• no supports required
• easy to print

Print Settings (tested)

Printer:

• Bambu Lab H2D

Recommended settings:

• Layer height: 0.16 mm
• Nozzle: 0.4 mm
• Support: not required
• Brim / Skirt / Raft: not required
• Material: PLA

The fit is designed to be secure while still allowing easy removal.
Adequate tolerances are built into the model.

Material Notice (important)

Suitable materials:

• PLA
• PETG
• ASA
• ABS
• PA

Do not use:

Carbon fiber (CF) filaments

Depending on the formulation, these materials may be electrically conductive and are therefore not recommended near battery terminals.

Safety Notice

Use at your own risk.
These caps are intended as mechanical protection only and do not replace proper electrical installation or safety procedures.
