Aftermarket Batteries

Hi, I just wanted to make everyone aware that there are cheaper alternatives out there when it comes to batteries or components.
I have a Haibike sduro cross with a 400wh battery and wanted a spare for longer journeys. At £849 (approx $1,100) for the official Yamaha 500wh battery I thought this was very expensive.
After much searching I've managed to find an aftermarket 500wh one from £388 ($507) which is a huge saving. I also sourced the Haibike stickers to complete the look.
Hopefully more companies will start to offer aftermarket parts.

It has been discussed on the German Pedelec forum for some time. Unfortunately, some of the latest feedback is not particularly reassuring:ür-yamaha-von-drittherstellern.46096/

It will be interesting to see how your own experience evolves over time.
I've been using the new battery for several weeks now with no problems and a substantial improvement in distance over the original 400wh but you're right only time will tell as far as quality is concerned.
A german company - electropapa are also offering a 600wh battery.
I considered this approach and did not take it. I found that my original dealer would cut me a USA deal and bought the backup official battery for $750 shipped. No worries about quality or warranty. Good luck and keep us informed how the substitute works out. Thx

I am glad to see 3rd party battery options. When it is time for me to buy a new battery I will probably go with the OEM, but I hope there are other choices available. Captive markets are not good and almost always lead to inflated prices.
