Bestech BMS switch- necessary to wire?

No need to limit the current :slight_smile: the current is only going to be as high as the LED needs. Do you have the switch already ? Nice if it can run on 6v voltage

Yeah I have it already but didnā€™t have time to connect it yet. Iā€™ll try tonight. I think with 5V it might be a tad dimmer than with 6V which doesnā€™t bother me at all :wink:

Niceā€¦ can you report back :smiley:

Will do !!

Mission accomplished! 5V works well!

Perfect thanks. I order oneā€¦

FYI it also has same brightens over 3.3V :smiley:

Is there any option, that it is possible to charge when switch is off? So the switch is just for discharging?

Bestech says the switch must be on. Thatā€™s all I know.

I wonder if these will work with 5v even tho it says 12v. https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F182825054149

Iā€™m pretty sure yes. I think the 12V is the upper range. Give it a try :wink:

the power for the switch is 12v?

What voltage us in the wires for the switch 12 or battery voltage in my case 42v?

@Acido I just measured the switch connected to Bestech bms and when switched off it is at approx 7.5V. When I switch on my board it goes down to 0V :wink:

Thatā€™s connected via Bestech bms switch cables which come with it as standard bare without a switch.

Led is connected to 5V output on vesc.

Cool thanks will bookmark your message :slight_smile:

@MontPierre. How has the switch been doing connected to the vesc? Do u have any pics?

Hi! Itsā€™ been fine. To VESC I only connected LED wires from the switch ( to 5V on VESC) rest is connected to BMS switch. Unfortunately, I donā€™t have the board with me to take pics at this moment.This should help.

does the BMS still balance at 42V (10s) when the switch is off?

With the metr app its kinda practical as you can set up a notification when the battery reaches its target voltage, letting you know when your board is readyā€¦

Canā€™t say for sure. The bms has to be on during charging per the manufacturer but it does appear to continue trimming after the charger and bms are turned off.

thanks :slight_smile: It should continue balancingā€¦
Iā€™ll email besetech. If I know anything else Iā€™ll let it know in this thread
