I always keep a battery tender on the E440 because of the constant small current drain they all have. I'd like to put on a lithium and not do anything for months like my Husaberg but I would need to put on a disconnect switch. It would also be good for extended camping trips. Automotive race car disconnects are really big. I was thinking maybe some type of 1/4 turn fastener on the ground connection would be simple and light. Has anyone done something else they liked?
Thanks
Edit - I was thinking of other options that would be more work but would be passive when the key is turned off. Since I have a key switch I could run some more relays and shut off the ECU where all the battery drain is. If I used relays for the fan (connected to the ATV fan connection) and the fuel pump, it would protect the ECU better and then I could turn off ECU power with a std relay from the key switch. Or I could use one bigger current relay and leave the fuel pump and fan driven through the ECU. Probably would want a diode to protect against voltage spikes from the fan motor when it gets disconnected when it is still on.
I have a lithium battery tender - maybe it's not so bad...
Any thoughts?
