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.
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.

@Joe – Unfortunately the battery indicators will not work with our new battery.
Will battery gage and range indicator work if I have two red and two black wires on Diamondback on the battery itself? how do I know how much time/range left with this battery then?
thanks

@Ron – We’ve really only had success with bikes that have two red and two black wires coming out of the frame. We’ve never had a Raleigh Cadent in store so we can’t guarantee anything.
Hi will this battery work with the Raleigh Cadent? Battery:417Wh DT Mounted Motor:TranzX M16 Center Mount 350W, Throttle Compatible
@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!
My 52v 16ah battery won’t charge. Can you guys help me?
