iZip E3 Dash 48V 17.5Ah Battery Upgrade

Do you want to double your range on your iZip E3 Dash, E3 Peak, or E3 Sumo e-bike? Previously, if you wanted an upgrade, we could only rebuild it to 48V 10.5Ah (improving it from 8.7Ah) due to the size of the case. Now, with some basic soldering, we've found we can offer one of our own 48V 17.5Ah Sea Lion batteries or Shark 2 Battery as a compatible replacement! This effectively doubles the capacity of the original.

E3 Dash Wiring

You just have to disconnect the original battery and the mounting bracket, exposing the wires leading down into the frame of the bike. Then splice the red and black wires together and connect it to our battery! There is no need to connect non-power wires to our battery. This has worked best for models with hub motors.

This kit could also fit on other bikes that utilize the Currie downtube battery pack, such as the Diamondback Trace EXC, Overdrive or other models.

While the middle two wires aren't connected, we've successfully installed new throttles with battery level indicators so you'll know how much power you have left. The indicator on the stock display and the estimated range won't function any more.

    I have a 2015 Diamondback Overdrive exc what are the blue and white wires for and do I need them to have this bike run again?

    Hello, I spoke with Shawn about upgrading my Currie 48 V-417WH battery for my 2016 IZip E3 Dash bike. I am going to be driving through Las Vegas in a couple weeks and wondering if I could drop off this battery. I understand it is no longer made so rebuilding it is my only choice? Thanks

    @Tony – Yes, it will take some wiring work on your part, but any of our 48V batteries will power your bike.

    Hi I have a Currie battery 48v 417 BL 17. And no longer holds a long charge so you are saying I can get a dolphin battery and just change the plug and I can use the dolphin battery ???

    Thanks. Tony
