Veteran Sherman Dual USB port/12v Voltmeter Install


Recommended Posts

  • fbhb changed the title to Veteran Sherman Dual USB port/12v Voltmeter Install

I looked into those same usb ports but found them too big to fit in the Sherman, but you managed to find a way.

 

Have you considered tapping 12v and 5v directly from the control board, so that you don’t need to have the headlights on to charge? The first batch control board had two jst male connectors supplying 12v and 5v that were subsequently removed in later board revisions. Soldering in the missing jst ports will bring back the functionality as Veteran didn’t redesign the circuitry.

 

I have installed a basic 5v usb port charger that pigtails out the back, with a 12v dc power port in the front to power any additional lights or accessories.

This install was done whilst fitting the second warranty replacement control board I have had to get from Veteran via my seller, due to the faulty standard 5A charger issue I have documented in another topic.  So bearing that in mind, I had no intention of carrying out any soldering work to a brand new untested control board for something that for me really is a non issue.

I am yet to clock up any serious mileage on this second warranty replacement control board before I can be assured that it's All Good and report back, having only ridden the wheel twice since the install.  Also, as I did state in the USB Charge port install description, the front light can very easily be unplugged with care if there is any concern over it being powered on during charging!

This is a cool modification that led me down a HUGE rabbit role of about charging rates for different devices and ports. Looks like the typical phone can accept anywhere from 1-2.5 A Max. Iphone uses lightening cable and other devices use USB-C/USB3.1

What made you choose this specific port, and does it really matter which port you use because they will all be 12V? For example, if I wanted to charge my speaker, should I use USB3.1 -> input or USB-C -> input. Explain it to me like I'm 5 haha..

Any idea what the max current output might be, either on the 12v light circuit or on the 5V and/or 12V pads on the control board? This is a mod I'd consider doing on my Sherman when it finally arrives!

The device he used has a voltage regulator inside. It’s converting the 12v of the Sherman front port to 5v for the USB :
