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.

    @Eric – We will be in touch regarding options. The Sea Lion is not necessarily your only choice.

    When is the 48v Sea Lion Battery going to be back in stock? My E3 Dash battery has gone dead on me, unable to take a charge so I’m in the market for a replacement.

    @Chritopher – Yes, send the battery to us for a diagnostic!
