🚧 Under Construction 🚧

2S3P Li-ion battery pack for CubeSat designs

• Fits 18650 cells (like the LG INR18650-MJ1)
• Meets maximum capacity requirements of common CubeSat integrators
• Uses components with radiation testing heritage
  • R5460x2xx for protection against
    • over-charge
    • over-discharge
    • short-circuit
    • excess discharge-current
    • excess charge-current

Tested against the following flight requirement documents: (the cells you use play a big role here)

• TBA

<aside> ⚠️ This is only a battery pack (with safety circuits). By design, there are no energy harvesting or power regulation functions on-board.

Connectors

The board has 4 spots for screw terminals (or whatever else you want to use) and 1 spot for a JST-style connector housing (our preferred method of connecting batteries).

The JST connector footprint accommodates either:

1. Surface mount straight
2. Surface mount right angle

If you're not experienced crimping these JST PH connectors, buy premade ones.

⚠ If you buy premade cables w/ connectors, be mindful of the wire color! Make sure it matches the polarity markings on the board or you're setting yourself up for trouble.
