Internal dimensions

  • Side to side: 266 mm (10.47 in)
  • Front to back: 248 mm (9.76 in)
  • Height: 73 mm (2.87 in)

Openings

The case has two 12 mm (0.47 in) diameter holes: one for a switch and one for a pressure relief valve.

What you supply

Cells, BMS, wiring, a latching push button or toggle switch (not momentary) and a pressure relief valve (both to fit the 12 mm holes), and two Amphenol SurLok Plus connectors:

You also need M4 x 8 mm screws to attach the connectors to the threaded inserts, and two M6 nuts for the connector terminals. We recommend these copper M6 flange nuts (opens in a new tab). Choose M6-2pcs.

Your cells and BMS need to handle at least 120 amps. See our FAQ for the cells and BMS we recommend.

Recommended BMS: the Daly Active 150A from the DALYBMS Official Store (opens in a new tab) (choose the 150A, 7S-17S option; the page may open on a different option, so select it before you add it to your cart). We don’t sell third-party parts and can’t guarantee them. Check that every part suits your build.

Recommended switch: this waterproof metal push button switch (opens in a new tab). Choose NO LED, Self-locking (1NO) and 12mm (1NO). Do not choose Self-reset; that is a momentary button and will not work with the Daly BMS. Another option is this 12mm mini push button switch (PBS-33B) (opens in a new tab), sold in packs. Choose a color marked Self Locking, such as Black Locking, not one marked Self Reset.

Recommended pressure relief valve: this metal waterproof vent plug (opens in a new tab). Choose M12x1.5, with nut. Another option is this plastic waterproof breather valve (opens in a new tab), sold in packs of 10. Choose Black, M12x1.5-10.

Is this right for me?

This is a DIY product for people who understand lithium-ion batteries. If you want something plug and play, buy a Flitecell from Fliteboard instead.
