IZIP eFlow E3 Nitro and Flight Battery Replacement

Posted on February 14 2018

Currie Tech released this innovative seat tube battery under their IZIP brand with the eFlow E3 Nitro and Flight models. These batteries run at 36V 10.7Ah (387Wh) or were upgraded to 14.5Ah (522Wh). Internally, they have 50 individual cells arranged in a 10S 5P configuration. What does this mean for you? It means we can upgrade your pack all the way up to 36V 17.5Ah (630Wh), giving you over a 60% increase in range, just one way rebuilt batteries are better than new!

    I think my E3 Nitro battery may need replacement as I’m getting an over current code on hill climbs between 15-16 miles and the battery is 5 years old. Not sure which capacity battery I have – I suspect the smaller 10.7 one. If it’s the 10.7 – what can it be upgraded to?

    I own the 2017/2018 iZip Protour E3 ebike. TranzX Curie BL18 integrated in tube battery. I’ve been riding extended rides and usually carry my charger to complete planned rides. I find this inefficient as I have to stop and recharge. Do you carry the BL18 battery as I would like to have a second battery to swap out when I ride extended distances.
