DC 8-60v to 10-120v 900W numerical control cc cv step up module with digital tube display, maximum current is 15A, with a fan to dissipate heat; adopts advanced microprocessor, can regulate output Voltage and current accurately, reliable and StableThe module has two kinds of modes: simple mode and fully functional mode(simple mode by Default); uses 4 digits high Brightness LED, can display output Voltage, current, power and capacity and other parameters; has out, cc, cv indicators, easy and convenient to check the working statuesSimple mode: after setting the Voltage and current values, pressing "OK" the module will output, then use the "↑" "↓" buttons to increase or decrease the value at output statue, short press "OK" to switch between Voltage and current display, long press for 3 seconds to turn on/off the function of displaying Volt and amp in turnsUnder fully functional mode, there are three special functions: 0 output automatically when power on; 1 save and call out the parameters, display power and capacity; 2 take turns to show the parameters after output automatically you can open them by yourselfWide application, suitable for wind power, DC generator, solar panels to charge battery, you can also make a Step-Up power supply to power devices
I'm thinking of building this with a 3D printed enclosure and a cheaper battery (so it doesn't cost a million dollars) and selling something similar. Any thoughts?
Build Tips:
The battery is expensive but I had one sitting around from an E-Bike that I built a couple years ago. Feel free to use any battery that can handle 200W of power draw and has a voltage of less than 60V.
If you plan of doing this make sure to use 14AWG wire for the connector and set the Boost Converter to 63v (3A for fast charger or 1.3 for home charger). As a note, for the GX12-2 connector the pins are numbered (found on the end of the connector) pin 1 should be positive and pin 2 should be negative. As I learned the hard way, solar charge controllers don't seem to work with the Pint so you need a boost converter.
Overall, the build isn't too difficult. Just hook up the battery to the input of the boost converter, set the voltage to 63v, the amperage to 3a (or lower if you want a slower charge). Then, wire the GX12-2 connector as described above. Attach the GX12-2 connector to the output side of the boost converter. Finally, switch on the battery to supply power, press ok and plug the connector into the Pint.
Sorry for the long post and happy floating!

Uh,
Not to pick on ya, but I think I made this sucker for $10 and it handles up to 30 volts.

this thing should be able to do it all.

Ohh yea, for anyone looking at going over 30v. 30v is pretty much the point where mistakes can start to hurt a lot.
​
I've got this thing sitting in a box to test out up to 120v when I can get some time to play with it.

I've used this buck boost DC-DC converter quite a few times in my van. It controls the voltage and current, which you can set and save.
Set it to the voltage and current ratings on the Boosted charger.
Displays the voltage and current. Constant current until 99% then the board controls switching the charger on and off. The brains are in the board. Full charge in normal time. Better have a spare car battery, like a deep cycle marine battery, it would kill your car battery.

I just measured the charge profile of the original charger. Then you buy
this guy https://www.amazon.com/gp/product/B01GFVI6R6, you attach it to a battery of your choice of sufficient capacity, and you program it to respect the same charge profile as the original charger. When you are at destination, you plug it in and charge the on-board battery.
Wow. Give me a flashlight and I can build it fine but this is harder. Would you mind checking my math please. I'll have 8 leds wired 2s4p and the vf is 3.7 at 4 amps. I'm coming up with needing 16A and 29.6v. Would this mean I will have to have a boost converter? If so I found this one, it's a lil bit more price wise but that's not a problem.

The only problem with the ego and using it to charge is that when your internal battery is low <40% and the ego is fullly charged it draws a ~10Amp current. The board wasn’t designed to draw such current. This is why with the ego people plug in theirs around >50% internal battery and ride which decreases the amps.
(I use an ego)
If you want to safely charge via ego to a dead internal battery I’d disgust using a voltage and amp regulator DROK Numerical Control Regulator DC 8-60V to 10-120V 15A Boost Converter, Constant Step Up Module Adjustable Output 48V 24V 12V DC Power Supply with LED Display https://www.amazon.ca/dp/B01GFVI6R6/ref=cm_sw_r_cp_api_00EWBbNKW4034
