Greetings!

Recently I have noticed some people have made custom lipo's battery boxes like Doc_Brown

I would like to know if anybody has experience with this type of thing, and how much voltage I can use without damaging motors

If you know of any brands of lipo's with good ratings I could look into that would be much appreciated, also I am considering getting an SBrick and would like to know if more than 9V would damage it.

Thank you

In a normal batterybox will go 6 1,5V battery's in serie, that means 6 X 1,5 =. 9V

So the s brick would run in a 9 V battery tension is the same amount as a normal batterybox.

I don't know what amount of tension is the max.

I hope I had helped you.

hello, 2S lipo batterys can be used with no problem with lego components (i do not know what minimum voltage the sbrick needs)

but if you want to use 3S batteries you will need a volt regulator like this http://www.jameco.com/1/1/105-mc7809ctg-standard-regulator-9-volt-2-2-amp-3-pin-3-tab-220-rail.html

1S lipos can be used with a 9V booster with this a smaller form factor can be achieved https://www.pololu.com/product/2116 (low output current between 250mA and 350mA !!!!!!)

You can also use high current diodes like the 6A10 (6 Ampere). The SBrick max voltage is 11.8 V but Vengit recommends a safe voltage of 10.8 V. A 3S LiPo will be ~11.1 V but when full charged can be a little more so I would use at least one diode (

I used a non-fully charged 3S LiCoO2 battery, 11.1V/1300 mAh, directly without any problems, reached 7.35 A).

Don't do this with PF IR remote, I don't think it can hold 11 V. Add more diodes or use just a 2S battery.

Any battery used in RC cars/planes can be used if it has internal protection (usually they have). A small 1300 mAh 20C battery can deliver 20x1300 = 26A so be VERY carefull. And even with a SBrick be carefull, 7A for more a few seconds WILL melt the plugs - I know, I did it :)

The minimum voltage for SBrick is around 5 V. I've used it with 4.5 V but the Bluetooth connection dropped when spinning a motor. A good/stable 5.0V will be enough for small motors, 6V will be better for higher loads.
