February 28, 20179 yr Several Yamaha owners on here showing interest in a new battery. Does this indicate the early Yamaha batteries are already starting to lose capacity? If so, that's a bit disappointing, and may be one of the reasons why Yam bikes are usually cheaper than equivalent Bosch ones. With great power comes the urge to have a second battery, for £300.
March 1, 20179 yr All sounds good so far, can you post up a pic of the new battery. Let's hope you can get the bike out for a spin soon so we know what the battery is like. I have about 1000 miles on my yam battery and it's still fine but at the price you paid it may be nice to have another one for extra range.
March 1, 20179 yr i always have two batteries comes in handy when you need to pop out somewhere again in a hurry and you don't have to wait around for a battery to charge up i normally make sure the other one is on charge before i head out with the first one i had no choice in buying another battery because i tow a trailer most of the time and the battery does go down a lot quicker when you are towing a trailer behind you i was going to buy the Bosch 500-watt battery but for what i needed the other battery for wasn't worth it at all really just pointless really easier to buy the other 400 watts which would suit my needs perfect then buying the 500-watt battery pack i don't have a car i have no interested in having a car my bike and my trailer is all that i need Mr Road Tax & Mr Insurance man won't be haven a penny out of me
March 2, 20179 yr Had a ride out with the new battery yesterday. I chose a very hard route in Nidderdale which sits next to the Yorkshire dales. The ride is extremely rugged which starts off with an almost 2000ft climb which is not only steep but strewn with quite large loose rocks. Once at the top the terrain gets little better and still strewn with rocks plus deep ruts. The descent is then still rocky but with bogs and soft ground thrown in. So still needed to pedal downhill. I used the highest power setting 90% of the time and covered 21 miles using approximately 60% of the battery. The battery charged up well afterwards and from the information gleaned from one short sharp ride I am pleased with it. So if your happy to take a recommendation to buy a £300 item on the say so of a man you found on an online forum. Go for it

Apologies for the Red bucket but it was handy.
March 3, 20179 yr wonder when / if they'll do bosch gen 2 battery. Probably when Bosch do a generation three. Sounds flippant, but if I recall pattern generation one batteries only became available when they were either superseded or close to it.
March 12, 20179 yr My Yamaha battery has carried me 6000 miles so far, approaching my second anniversary commuting and is holding up really well. I will be very interested to see how long/far it takes me before I need to replace it as I enter my third year of ownership. However having an alternative choice to the expensive Yamaha replacement has got to be a good thing for any owner.
March 13, 20179 yr a place in germany will now recell gen 2 batts Wonder how much. It's early days for me as battery only a year old, but a fair few miles on it. I'm thinking about a spare for when I go bike packing.

May 5, 20178 yr My Yamaha battery has carried me 6000 miles so far, approaching my second anniversary commuting and is holding up really well. I will be very interested to see how long/far it takes me before I need to replace it as I enter my third year of ownership. However having an alternative choice to the expensive Yamaha replacement has got to be a good thing for any owner. I bought a 470 watt replacement battery built with Samsung cells from Allbatteries.co.uk, which at the time was on special offer at around £300. I think they are now around £330. Works great, I am very happy with it and not only have I requested a delivery date for one of my riding partners, I have also just posted a picture of it on the Electric Mountain Bikes section. The batteries do not come with logo's I have added them myself. Edited May 5, 20178 yr by Izzyekerslike

October 17, 20187 yr Hi all, I'm after some advice on replacement batteries for a Haibike sduro allmtn rc 2015 model as the battery BMS has given up. Trying a battery from a local shop shows the bike motor / display works so a new battery is required......but not £750 price! I ordered one of these as it looked a perfect match https://www.batteries4pro.com/de/Mobilitat/Elektro-bike/3,15269-36v-li-ion-13ah-akkutyp-yamaha-winora-y280-x-haibike-sduro-3052351243985.html It arrived but doesn't work, nothing on display and 17v DC on +/- pins. I also took it to local bike shop and it didn't work on their shop bike, so it goes back. I called allbatteries in UK and they say they don't have anything compatible with my bike. The battery I have shows the following info.. 36v 11ah 400w ( would like bigger capacity,) PASB2, B94-20 & X94-20. What's a compatible battery for my bike, hope someone know..... Graham
