Plant led grow light box for 10 LEDs. I made mine with 5 blue leds, 5 red leds, 2 18650 batteries, battery charger module and a cycle timer relay switch. Did not put opening for the buttons and screen of the timer as I am going to set it once and forget, if I need to change the cycle I can always open the box.

There is also two mounts, one which can be screwed on a wall and one which can be hooked with cables/rope.

The box slides into the mounts very easy, so one can take it off to recharge or service conveniently.

The opening in the top cover is for the charge module and led.stl which transfers the charge indication lights (led.stl should be transparent)

Parts used:

• 5x 5mm blue LEDs
• 5x 5mm red LEDs
• 2x 18650 li-ion batteries
• 1x on/off switch
• 1x charger module TP4056 (the version allowing charging and use simultaneously)
• 1x Kkmoon LED Indicator Automation Digital Delay Timer
• 5 56ohm resistors (if blue led is around 3.3v which is quite common)
• 5 100ohm resistors (if red led is around 2v -2.2v, which is quite common)
• cables

Not sure what the make of the on/off switch is, I have many laying around bought from somewhere years ago, the opening in the design for it is L:19mm H:14mm, should be pretty standard size I think

I used this thing for the batteries: https://www.thingiverse.com/thing:2339441

In mine batteries are soldered to the charger module, the the module outs are connected to the timer module, the on off switch is in front of the timer, then all leds are connected to the relay switch of the timer.

100ohm resitors are soldered to the red leds and 56ohm leds are soldered to the blue leds. All leds are wired in parallel. You have to check your LED's specs to see if this resistance will work for you or calculate what resistance will be needed

Batteries are connected in parallel to double the capacity while keeping the voltage. Putting more batteries in might better if you want it to last longer between charges.
