Hi I telephoned Jimmy on Friday he was in fine fettle. He is 69 but still going strong. If he does ever retire - there will be a lot of disappointed customers .

 

I'm so glad to hear that. It didnt sound good from what they told me last year.

I replied telling them that Ive done over 300 miles since on the original battery and there have been no problems. I have also requested they tell me how to replace the fuse in case it blows again. Perhaps there is a slight issue with the motor but I dont believe they are service-able items and need replacing entirely if they break.

Perhaps the fuse was a bit duff from the outset. I guess time will tell and I haven't given up on the spare battery. I will just have to always make sure I carry both and never rely entirely on the spare.

Well, their engineer has offered nothing in the way of a how to replace the fuse guide because "It requires opening the battery case". No shit, sherlock!

I doubt it will be rocket science but it would have been nice to have had the heads up.

 

I had to recently open my Yamaha battery on my Haibike to replace a broken charging socket after my dealer told me that the suppliers did not offer any facility to repair it leaving me with the only option of buying a new battery and charger or repairing it myself.

 

No prizes that I decided to try to repair it myself. We ended up opening up the battery and soldering the wires directly inside where they cannot be bent or broken.

Nothing dreadful happened when we opened the battery case and the battery charged just as before when we had put it all back together.

Good work! Well I have replied saying that having rebuilt engines in the past I think I could handle opening up a battery. Doubt it will help much. Like you say, just a heads up like "do this, dont do that, remove this, the fuse is there" etc would have been great. I get the impression the engineer is a moron who really couldn't care less. Oh well. When it comes to it I'll have to take my chances.

I'm in Australia, I ordered the battery from China. I charged it up a few times only. Back when it happened, I didn't know if it was the motor or the battery that was at fault. Its only that I found your posting that I realised we have the same problem. Screen shows all of its display for a few seconds, then turns off. I cant send it back, so I am stuck with it (impossible to send Li batteries, no one in Australia will handle big Li batteries)

Hi Aaron,

Just a thought that you may have been very unlucky !

My "pattern" Yamaha battery is still working fine and has done for the last 18 months.

At the moment you have a bike that's useless and if you are certain it's the battery the only possible way forward I can see is to bite the bullet and buy another Chinese battery.

I realise it a gamble but if it comes off you'll be a very happy rider.

 

All the best.

It might be worth opening it up and seeing if its the fuse thats blown, although your symptoms seem a little different as mine wouldnt fire up at all.

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.....

Looks like the right battery to me It says 36 V so should be the right one but that 17v reading suggests it is faulty and is why it doesnt work in the bike.

Hi, You must have spoken to the wrong person at allbatteries.co.uk.

I have a 2015 haibike allmtn rc and have had one of their 468watt batteries working perfectly for almost 2 years now. They have them on their website.

 

http://www.allbatteries.co.uk/electric-bike-battery/yamaha-motor-36v/haibike/sduro-allmtn-rc-aml9144.html

That's what I thought, hope it's faulty and it's not me going mad.

If I checkout Amazon allbatteries sell there also on this link...

So is this compatible with my battery?

It shows B94.......20 & x92......20 my battery just missing the middle numbers!

Thanks Izzy

Do you have the old battery just to check the numbers are the same as mine?

Love the bike but not good it's taking ages getting a battery and no idea why the old one failed

Numbers on the back of the Original battery are B94-20.

If you buy it from Amazon and it's not suitable they refund so nothing to lose.

The original battery has the code B94-20.

 

Izzy

Thanks Izzy for the confirmation. I'll speak to allbatteries once I get my refund for the faulty unit from batteries4pro.

Maybe buy it from Amazon as returns and refunds are simple.

Hi. Just bought a 36V, 17AH battery for my 2015 AllMtn RC from electropapa.com (which seems to be the online arm of a German company). Battery arrived in good time but when I put it on the bike and switch on, nothing happens apart from all symbols on the control panel light up for a few seconds and then it switches off again (goes back to just showing the time). I put the battery on charge overnight but the problem is the same. Today I used a multimeter across the + and - slots on the battery and got a reading of 2.74 V. Battery knackered, or am I possibly doing something idiotic?

Thanks for any suggestions you might have.

Fraser

Batteries with a switch have to be switched on to get a reading. Also some may need mounting on the bike to allow a voltage reading, in which case if careful you could rig the battery up so as to enable you to get an out put reading.

You can only read the voltage on a Yamaha battery with the battery on the bike ans switched on. Be careful of the third terminal with your multimeter, if you probe it to the wrong side you will kill the electronics! (With an OEM BMS)

Thanks chris_n and Nealh -- I'll have to figure out a way to get a voltage reading without frying it. Would you say the control panel lighting up and then dying is symptomatic of a bad battery, or could it be any number of things?

Fraser

It is symptomatic on no communications between the battery and the display. It is possible that dirty connections can cause this but usually it is the battery that is at fault.

Does the original battery work?

Have to agree with Chris looks kike a coms or connection issue.

However if battery voltage is bad then looks like a battery issue.

 

Do you still have the old battery ?

I had to leave the original in Korea when I shipped the bike back to UK so unfortunately I have nothing to test with. The terminals look clean, but I'll give them a polish and see if that helps.

 

I realise now that this same problem has been experienced by a couple of other posters and it appears to have been the battery in both cases. I've written to the site I bought it from and hopefully they will play nice! Thanks for your help, chris_n.

You don't get actual voltage until the battery is on the bike and turned on. I have an extender battery on mine, if I measure the voltage it will increase when I turn the battery on.

Also worth noting on the OEM battery if you try and put a load on (maybe a lamp) with the battery not switched on you will kill it.

Thanks, NealH! Bit gutted, but hopefully things will work out.
