New Battery or new bike.

[scifibuff66]

Hi all
My wife and I have been ebiking for about 3 years now. I have asked for help on this forum a couple of times and have received the help required to get me through a few problems.
If anybody followed any of my posts they would know I purchased my wife a second hand bike from a friend that was approximately 18 months old. The bike was never used and the battery was looked after and charged regular. I changed the controller on the bike to give a little more flexibility with the ride and the battery is still performing adequately.
We have had the bike 2 years and it was nearly 2 years old when we purchased it. I have been looking around for a replacement battery but it seems batteries have increased in size and there is not enough room behind the seat where the battery is located to fit a new one. The height is not a problem or the width but the depth is about 10-15mm too small. That's the problem with buying a second hand bike that is no longer in production.
Has anybody else had the same problem with older bikes? Any suggestions would be greatly appreciated if I can get a solution now I have time before the battery loses it's power.

Can you post a photo of the bike Eddy? Alternatively the three dimensions of the case could help.

You can still get the narrow batteries, but we need to know what size it is and what bike.

Battery dimensions. 462mm height X 82mm depth X 82mm. The bike is called a Vitesse s4000 a step through bike. Much the same as most step through bikes but with less room for battery. Please find attached some photos.

10aH one:

Have a look round Aliexpress for silver fish battery.

if you can't find the right casing, it may be more straightforward to get a rear rack battery, something like this smaller one of the two for about £200:

Thank you for all your replies. I think the best way to go will be to get a rear rack battery. BMS seem to do the 24 volt at a reasonable price with a fitting kit.
One more question the battery is 24 volt 10AH could I buy a 24 volt 15AH and not have to change the controller? And what would the advantages be if I could change from 10AH to 15AH.
Thanks
Eddy

If my country we have a company, that can fox old ebike batteries for about 50 quid. Maybe there are also such companies in the UK.

15AH would give you increased range, but will be slightly heavier than the 10AH, and should also give you top performance for longer, but it won't damage your controller. If you want increased range, go for it.

A 15 aH battery is always better apart from the weight.

Hi all again.
I had almost given up and decided to order a battery for the back pannier. The bike is based in Spain so it would mean ordering from china and either delivery direct to Spain or delivery to UK and courier over. All extra cost.
I have found a bike company in Spain that will refurbish the battery keeping the same aluminium case for around €299 (£250). They say it is possible to upgrade to 15Ah if I wish and with a years warranty. This eliminates the problem of long distance delivery. Although I will have to pay double courier but by my estimation should be less than €100. So I should get a battery that fits for around the same price as a new battery. Result
Just thought people would like to know will not need to get a new bike.
Thanks for all advice
Eddy
