I am looking to buy a replacement battery for my Pendleton Somerby but main suppliers don’t stock due to age, it seems. Any suggestions please?

Halfords sell them here. Yose sell them here. It's a standard Phylion/Joycube battery (SF03 IIRC - double check the case profile) used by thousands of e-bikes across Europe, so my guess is it'll likely be around for many years yet.

Thank you. I will check it out but Halfords (store) say they cannot supply.

Our local Halfords still sell the Pendleton....
Yes, but the battery maker/style changed in 2018/19. Newer Pendletons use a sleeved battery. Both Halfords and Yose sell both types.

That's interesting......I have just bought one, and am trying to find out what year it is.........

That Halfords price of £300 is ridiculous. You can buy a complete new battery with much better cells, rack and a much better controller with LCD for less than that.

The price may be a bit fruity, but IMHO it's not so bad. Phylion use pukka Samsung/Panasonic/LG cells. Being 8.8Ah it compares fairly well to say MiRiders Samsung 7Ah also at £300 or any Bosch/Yamaha et al using similarly branded cells. An original Phylion 11Ah version of the OP's battery in the EU is currently 360 euros, but that supplier no longer ships here since Brexit.

The Yose uses DMEGC cells, compared by the Vape guy as a pretty decent if cheaper Samsung cell equivalent. One of my own e-bikes uses these and they seem okay, if not spectacular.

If you want to be really cheap about it, you can buy ready assembled cell packs of unknown provenance from Alibaba that fit; for some that may be perfectly adequate.

Make date is often included/embedded within serial/model markings on (for example) the motor, controller label, or the serial number stamped into the bike frame itself.

Phylion batteries have never been much good, as demonstrated by OP's needing replacement. We've had many other people on this forum asking about replacement too, and Pendletons haven't been round that long, and they're probably not used much. If it were my bike, I'd get a different battery.

I've got two Phylion batteries, both from 2016, each rated 10.4Ah/374Wh, Samsung Pinkies. They still measure (very near) that on a full measured charge/discharge cycle. To be fair they don't get daily use, nor do I demand too much given their modest rated discharge. As often the case it depends how you store/look after/use them, and I'd argue that a typical Halfords Customer probably/often doesn't know how or really care.

Also worth stating, mine aren't the "smart BMS" variety, which appear to be the ones with a reputation for cutting out mid-ride. Mine have NEVER cut out like that.

They're not a top-flight premium battery for sure, but fairly respectable given the sea of Chinese tat that seems to pervade much of the "affordable" market.

I bought a new cloned/Chinese Bosch power tool battery off Amazon last week, rated at 3600mAh both in the advert/listing and on the battery label itself. It weighs probably half that against a proper one, and measured 1200mAh when cycled.

Phylion batteries always seem to give full voltage. It's the current they cant give when they wear out. They're OK, but nothing special. The very old ones with prismatic cells were terrible.

Thank you so much for taking the time to give such a useful reply. I am delighted that there are so many on here that genuinely want to help me find a solution!

To give more background on what I seek. I bought a Pendelton Somerby ebike second hand in 2020, during lockdown and have never actually used it but have had it fully serviced by Halfords but they cannot supply a new battery for this age of bike - I dont how old it is. I am awaiting 2 x total knee replacements and feel that cycling will help me to strengthen the muscles around the knees to give me a chance of a quicker recovery, so my use of the bike will not be extreme!

I cannot claim to understand the technical descriptions of the batteries and all I want is one to give me enough charge for short trips.

If the batteries you have will definitely fit my bike, I would appreciate discussing this further.

Many thanks again.
Diane

What is actually wrong with your battery? Did you try to wake it up?
Hi
All I know is what Halfords told me when I took it in after charging it overnight. They said that the battery wasn't charging, but the charger was not faulty. Its not helped by the fact that I have lost the key for the battery so cannot take it off the bike. If there is a chance of getting a replacement battery, I am happy to get a locksmith to remove the battery for me.

You can probably unlock it with a set of jiggler keys. You sort of rake and jiggle the key while turning it slightly, and the lock opens. I've opened loads of ebike batteries with them. They seem to be designed for ebikes. I just tried my latest battery and couldn't open it after trying for about 5 mins, so it's not guaranteed.

That’s really useful information. Will order and give it a go. Thank you!
