Overtime pack, when to use?

[jeffreyb]

Got an overtime pack during the sale and now wondering what the best way to use the overtime pack would be on those long days.
Should it be used at the beginning of ride when both batteries are fresh? Mid way when the main battery is partially drained? Does it even make a difference?

I have mine plugged in to the main battery from the beginning that way the iwoc sees it as one massive battery.

Yes - run it from the get-go - it will charge your main battery as you go, but if you are in modes 2 or above the bike drinks faster than the OTP fills the battery. So waiting til the end of the ride you'll have to run mode 1 or maybe 2.

I got 2 OTPs and on mode 4 for a whole ride the bike battery goes to zero (or close) before the second OTP is empty. I got home on 2% when I tested that out.

Here's another use case I just experienced - headed out to the garage, put on the pads and shoes, turned on the bike - "wait, why is the plug on the floor?!" - put the OTP on and headed out with 38% on the bike for a quick rip, worry-free.
