    Alternator has gone and thinking to buy brand new (not refurb) 120amp alternator given the electrics car has and possible future upgrades.

    Was looking at a Bosch 120 ah battery but the dimensions sound like it's too big to fit. Any recommendations for a Bosch 120 ah battery? Or would a 100 ah suffice?

    Thanks

    Get the battery that fits properly.

    Don't worry about the alternator amperage - it may be capable of providing 120 amps but in practice it will only supply what is actually needed.
