🚧 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)

⚠️

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:

Surface mount straight

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.
