Can I adopt normal water Bootle battery to Bosch powered ebike

[braham]

Hi
Thanks in advance for your help.
My gepida berig 1000 needs a new battery. I already have a working water bottle 5th battery. Would it be possible to use this battery on this bike given it's Bosch powered bike? My water bottle battery has just 2 cable (red and blank) where the battery connexion coming out of the Bosch engine have 4 cable (yellow and green plus the usual red and black) .
What are these additional cables for? Can I adopt them to my existing battery?
I will try and add some pics if I can. Thanks again.

No, Bosch system uses information from the BMS IIRC.

Thanks for the reply @anotherkiwi .
Is there any known solution round the issue of the very costly Bosch battery?

Yes
Put it on an interest free card and pay monthly
