battery reverse charging a2b hybrid 24 and extra charger needed

[ajp]

Good afternoon

I live in South Wales and my A2b Hybrid 24 battery has stopped charging - does anyone no anywhere I can send it or take it to get it reverse charged or tested ?

Also I need a spare charger for work - does anyone know of a cheaper alternative to the a2b chargers for the above bike.

Thank you

Do you own a multimeter ? The forum can talk you through some tests to work out the issue (charger , cells or Bms board are a few points of failure )

How old is the battery ?

Also , I don’t know what you mean by “reverse charging “ can you explain ?

To me that means connecting a charger the wrong way round to a battery ! You don’t want to do that obviously !

Plenty of chargers about but useless if yer battery is broke!

Hi...If this is not a regular occurrence you can use a fuse between batteries with the right rating. This would allow the batteries to equalize as long as they are not too different, but if they are too different the fuse would blow.
The fuse of course has to be able to handle the full load current too though.
