🔋 XT60 Balance Box – for Parallel Charging of 4S LiPo Packs

📌 Project Description:
This is a practical balance box for parallel charging of 4S LiPo packs. It allows you to safely connect and organize multiple battery packs to a single charging line, keeping everything neat and secure during the charging process.

The design is tailored for FPV and RC hobbyists who frequently charge multiple 4S packs at once. All connectors are fixed in place with two-part epoxy glue, and the printed enclosure keeps everything tidy and stable.

🔧 Features:

• Designed for parallel charging of multiple 4S LiPo battery packs.
• Clean and compact layout with 7x XT60 and 7x JST-XH 5-pin 2.54 mm connectors.
• All connections are glued for long-term durability.
• Easy plug-in and removal without messy wiring.

🖨️ Printing Recommendations:

• Best material: ASA – ideally printed in a heated enclosure.
  ⚠️ ABS is not recommended without an enclosure – high chance of warping or delamination.
• ✅ However, it is possible to print ASA even without an enclosure – this model was successfully printed on a Bambu Lab A1, which has no chamber.
• Alternative: PETG (for better print reliability on open printers)
• Layer height: 0.16 mm
• Infill: 15%
• Supports: Not needed
• Glue: Two-part epoxy (for connectors and enclosure assembly)

💡 Use Case:
Perfect for RC and FPV enthusiasts who want to balance multiple 4S packs at the same time in a safe and organized way. Great for:

• FPV charging stations,
• workbench setups,
• mobile charging rigs.

⚠️ Disclaimer:
Be careful when soldering! Improper installation of connectors may lead to short circuits, fire, or even battery explosion. I take no responsibility for any damage caused by incorrect assembly. Use at your own risk!
