I thought it would be useful if we could use our RAD eBike battery for back-up power or for camping. I designed and 3D printed a battery adapter. I also verified that you can use an MPPT solar charge controller to charge the battery. You can charge it at 120W while using the output power. Now we just have to convince RAD Power to manufacture/sell something like this as an accessory 🙂
I put the 3D print files at: https://www.prusaprinters.org/prints/70263-rad-power-ebike-battery-adapter

I like your way of thinking, I love finding ways to multitask items I own, this is a natural fit. Where I live in NewEngland my bike will be stored away each winter, November - March, 5 months. It would be great to use the RAD battery as a power Backup in case of an outage over the winter. In addition I'd like the ability to cycle the battery occasionally. RAD really should have included USB output on the battery case.
Please let us know if you find out why one of your batteries would not work with the inverter!
Just a thought: If you are interested in a little business venture, There are a few sellers on ETSY selling 3D printed covers for the RAD battery and battery mount terminals as well as thumb levers for the throttle. I'm guessing you could sell quite a few of the battery connector you fabricated.
