Help to fault find on a Carrera Battery

[Baz the balloon man]

The

Panasonic (aka Panny) PF cell, 2900mah rated for 10a but typically for a longer life use at a max of 6 -7a per cell. It is a very good cell.

Like the Sam 29E one of the most prolific cells used for batteries.

The Bird Bike battery is knackard not holding a charge and just crashes once any load is put on it probably the reason it went back to Halfords under warranty.

I have a chap interested in buying the bike without a working battery , I have advised him to just buy a new one from Ali Express but the adds I found have disappeared.

So now trying to find a reputable company to re cell it for him .
Any recommendations ?
or which industry accreditation should they have ?

I have advised him and many others now asking me for advise on e bay to join this Forum .

Cheers
Baz

Re-celling a battery is very expensive. Are you sure you can't find a replacement battery on Aliexpress?

they where being advertised around £180.00 including delivery but the ads have gone.
iI just e mailed the main manufacturer in China to see if I can purchase directly.

However a couple of the companies on e bay have both said they suspect it may just be one cell group that has failed could be as little as £60.00 quid after a full test. To get it going again

or from £200.00 to re cell with a branded cell’s then upwards of that depending on which cells they use Which is fair enough considering cost of a replacement from china if they then offer a warranty .

I have left it with the potential buyer to do as they wish , the current battery has enough to test the bike out. But in true e bay style they have gone quite gumtree is a waste of time too I used to sell lots of vans on there.

we are off to Vietnam at the end of the week so I will sort it all when we get home if it does not sell before we go.

passing through China I may stop on the way home and buy some bits .
Guangzhou seems to have a lot of electronic companies.

Giant now have a factory in Vietnam too !!

A Bird bike battery LOL and a

I suspect there is no such thing as accreditation for recelling an ebike battery.
