Thanks for the vote of confidence! There are 5 pins on the battery and mount, 2 for positive/negative, but the other 3 seem to have something to do with the original battery and it’s charger? I can’t remember why, but I’ve been lead to believe that there’s no handshaking between the battery and the controller, but there is between the battery and charger- so hopefully it just works!

Hi all, apologies if this is a supernewbie post! I have a carrera subway e from halfords. The battery is dead because the lipos let me down over winter. Can I use a yosepower 36v 20Ahbattery and wire it into the positive/negative terminals on the bikes controller? Is there anything that’ll stop this working as I see it in my head? Any advice that isn’t “spend £385 on a battery from halfords” would be greatly appreciated! Cheers!
