    In-situ Battery charging

    Hi,
    Can anyone advice me which is the best way of in-situ battery charging?

    I had thought of installing a DIN socket to one of the the standard bmw oa connection with an Optimate 4 CAN-bus but the dealer said ‘ never charge using a DIN socket as it switches on instruments/ ignition, activates it somehow so when the battery has finished charging the ignition or something is still on and drains the battery ….. or something along those lines’. 
    Alternatively I could connect the Optimate directly to the battery but my understanding is that the charger reacts differently this way.

    I’d greatly appreciate you help.

    Joe

    Connect straight to battery. Charger does not act differently.

    Thanks guys,
    my impression from Optimate was that the charger behaved differently when it was connected to a DIN can-bus connector rather than directly to the battery?

    Unlike some other BMW bikes the S1000R doesn’t have a din aux socket, so most of us just use a regular charger, using a pig tail lead directly connected to the battery.

    If you have an Optimate for use with BMW canbus, just switch it over to the normal setting and use a direct connection to the battery

    Hamburg has the right plan. Not everyone has an Optimate with the CAN bus system selection. Mine does not. I have a DIN Socket directly wired to the battery via a 15 amp fuse in line. I have this so I can also use a heated vest or a mini air pump for flats. This or a pig tail SAE socket is the first thing any of these bikes need.

    i went this direction with a cable socket to charger. (my only concern is theres no inline fuse between battery and connector but you could easily add one.

    The no fuse should be ok unless the positive lead rubs through to the frame. Someone at the charger company was saving money. Most motorcycle shops sell the pigtail with a fuse in it and at some point I suggest you use one of those. Then you will be safe from normal wear and can use the circuit for other needs. (like a heated jacket liner)
