I'm still mulling over the idea of adding a DigiNow SC setup to my 2017 SR. If I have a 2 or 3-SC setup, can I add more chargers by just buying Elcon TC HK-J 3300W's? Or do I need to track down charging units that are specific to DigiNow? If the former, would I need to update the firmware on the DigiNow brain and/or Elcon charging units?

I saw DoctorBass's video about adding a 4th charger at the front of the bike to a 3-charger belly pan setup and love that idea. With 4 chargers, I would likely have 2 J-plugs at 6.6 kw each and a Tesla destination plug at 13.2 kw or the full 16 kw if possible (after the battery warranty expires next year). For longer trips, I might even want to carry 2 extra chargers for a total of 6.

I think you can put up to 4 chargers with a single diginow interface. The max kW limit is 1C so if your battery is 14.4 then you can dump up to 14.4kW total

On my SR i have the power tank so this bring yp to 16.3kW ( 16.3kWh)

But i am not 100% sure of that 1C is based on the advertized kWh by Zero or if it is based on the real usable kWh. The 14.4 battery is made of two bricks of 64Ah ( 128Ah total) at 102V = 13.05kWh - at 1C 13.05kW of charge power.

I'm guessing your 2017 SR is the ZF13 pack. That is a 104Ah battery. Each charging brick puts out 32A to the bike. 3 of them is 96A which is juuuuuuuust about the limit you can charge on that bike, so you'd not be able to do 4 unless you a.) add a Power Tank or b.) override the safeties and contactor of the battery. Do not do B unless you know exactly what you're doing and understand that your warranty is totally void.

I haven't tried to use the units Elcon has but I don't like their massive metal connectors coming out the sides. The ones we used were made to our specifications from the manufacturer (TC) and had wires sheathed in rubber coming out so they'd fit in tighter places easier. You'd have to figure out the CAN wiring on the Elcon unit, as in which one is 12v +/- and CAN high / CAN low. If you can figure all that out and make a splitter to merge into the control board it might work.

Thanks guys! Sounds like I should find a setup that already has the number of SC’s I want.
