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!
