TranzX Battery Cell Replacement Service

Posted on October 18 2018

Raleigh TranzX BL07 Battery

TranzX is a company that makes parts for a number of e-bike manufacturers, including batteries. When the battery dies though, replacements can be tough to come by. That's why we offer our rebuild service! Send in your battery, we replace all of the cells while re-using your case (so it's guaranteed to fit back in your bike), and send it back to you! Often, we can upgrade the capacity to give you longer ride time as well!

TranzX BL17

Here's the popular TranzX BL17 model battery that's used on iZip E3 Dash, E3 Peak, and E3 Sumo model bikes, along with the Raleigh Tekoa, Route, and Misceo, among others. It fits on the downtube. We can upgrade these from 417 Wh to 504 Wh with our 10.5 Ah rebuild.

Raleigh Sprite Battery

This is the TranzX BL07, a rear rack model, that Raleigh used on some of their electric bikes like the Retroglide, Superbe, and Sprint. We can also upgrade these to 10.5 Ah using our rebuild service.

    @Autumn – We’ll be in touch to see what we can do, but it would be better to have someone that can put their hands on the bike do some diagnostics.

    My tranzx pst battery may be faulty. It ran perfect until I had a bike shop replace a tube in my back tire. I got it back and my izip will not turn on. The battery looks like it works…the lights on battery come on…but I am getting flashing lights or no lights at all on my bike. I am not mechanically inclined at all. Any feedback will be super helpful to me. Thank you and have a blessed day.

    Hi, I am an engineering student at Dublin Coffman High School. Me and my teacher are looking for a replacement battery for an IZIP E3 PATH+ which is a TranzX BL-07 48v battery, do you have any in stock? If not how much would it be to repair the battery? it appears that it was dropped.

    Thank you

    Hi. I have a izip bl-07 battery that I dropped and broke the case. It still powers on, but some of the internal components are exposed. Are you able to replace the outside case and if so, what would I cost?

    @Tracy – We can rebuild your battery if you send it in to us, but we are unaware of any dealers in Oregon that carry them.

    Where can I get one of those Batterys in Oregon TRANZX PST 48 volt battery

    @Richard – Not sure if the charger needs the thermistor input to operate. Otherwise, you can just wire up the + and – wires to whatever connector you want.

  • Richard Lindgren: October 01, 2019

    Is there a way to turn a 3 wire TransX BL17 XLR-type charger into a regular two-wire? I understand the extra wire is for a thermistor in the BMS. I am done with the battery and would like to use the charger at work for a different 13s battery with an XT-60 charging plug. 3v between green/black, 5v green/white. The wires in the charger are white VOUT+ (connects to red in TransX battery), black VOUT-(black in battery), and green VOUT-NTC (blue in battery, connected to thermistor from BMS). Any help would be most appreciated. I hate to throw the charger away. Thanks in advance. -Richard
