Pendleton Somerby Ebike Battery

[SopwithCamel]

Hi all,
I am looking for a little help with my wife's Pendleton.
The battery is refusing to take a charge, it was left for about 8-10 months as my wife was unwell, it was about half charged.
The bike has been in our spare room so constant temp.
I've had it plugged in now for about 6hrs and not showing any charge taken.
The battery is the orginal JCEB360-8.8 which i understand is Joycube.

If the battery is screwed fine why do i find another one?
Thanks for your help

I am a little familiar with that bike. But some more detail. Normally, the charger plugs in and the red light comes up on charger to indicate battery is charging. After a period of time (about 4 to 5 hours max), the light turns green to indicate battery charged. The charger also gets a little hot during the charging state but this is normal. Sometimes the main cord connector gets a little loose on charger end and this will prevent charging.
The battery has a button and 5 green lights/leds. The battery can also go into hibernation mode. Press the button momentarily. What lights come on? This might reset BMS (or bring battery out of hibernation) so try disconnecting the charger and reconnect again? What happens? Push button for a good 10 seconds. What happens?
I have attached a similar battery manual that might be helpful.
The green lights can show both battery state of charge and state of health or error codes as outlined in document (provided battery has some life left in it).

Hi, thanks for your reply.
The charger goes red for approx 5 seconds when plugged in to the battery.
No heat on the charger or battery...pressed the button for up to 30s and nothing from that either.
It's so annoying as wife only used the bike 5 times before she got ill, so it's basically brand new.
I'm thinking the battery has fully discharged over the dormant time.
If that's the case need to get a direct replacement?

I think Halfords gave a two year guarantee with that bike and battery. How long have you the bike?

we are about 3months over this, so they’ve won’t help.
Any idea on where to get a replacement battery?

One further test. Try removing battery from bike (you need the key) and then try to recharge.
I am disappointed to hear that Halfords wont look after you. I am a bit slow to recommend you a replacement battery as they are quite expensive and there is no 100% guarantee that they work or indeed that there is not some other fault with the bike.e.g controller. A small bit of testing and rewiring is also necessary to get some of the replacements to work.
You could consider sending your existing battery and charger off to be refurbished with new cells. This guy below is highly recommended by some site members.

Had it off the bike and on trying to charge.
I’ll speak with your recommendation and see what the cost is. Thanks again

At least one of the cell groups has likely discharged below 3.2v so the BMS doesn't allow any charge until it is rectified, the voltage needs to be manually raised but this requires the battery to be opened.

Ok, so is this an easy job? Or needs a person that knows about these things?

Depends if you are a practical person and also able to trust and follow the advice given, all that is needed is a screwdriver to open the battery and a multi meter for voltage testing of the 10 cell groups.
The testing of cell groups is only to see where the issue might lie and not a fix, the fix requires a little more skill knowledge but nothing most people can't do if they have managed the first tasks and may involve soldering.

Pictures are a must when dealing with afar issues, so we can get a better idea of what we can see. No two are the same or can be taken for granted.

Is this an easy thing to do or does it require an expert hand?

Ok sorry re read your reply.
I don’t have to tools, so buggered!
Thanks for your help

Apart from ebikebatteries as mentioned as a possible re-celling option, check here to establish which shape/type of Phylion's rear-rack batteries you need (the code you gave doesn't help):

Rear Carrier_PHYLION - ELECTRIC VEHICLE LITHIUM BATTERY_NEW NATIONAL STANDARD LITHIUM BATTERY_XINGHENG POWER CO., LTD.

Rear carrier battery: powerful, easy to carry.

www.phylion.com

It's likely a Wall-E or SF-03, but the other shapes/styles are reasonably common too (case shapes differ, so you need to be sure if it's going to fit your existing rack). Likely sources are Ebay (Yosepower or Elife often stock them), Amazon, or bike sellers such as insportline.eu.

You also need to be sure that if your existing battery has a "Smart BMS" fitted (it should have a sticker on it to say), your replacement battery has too. All Phylion batteries are available with Smart or Not Smart BMS, the latter usually being a bit cheaper, but won't work if your e-bike needs the Smart version with comms.
