Bought a megaboost battery from cycle gear and have had nothing but problems. After 40k miles I felt my stock battery getting a little weak, so I bought the megaboost... they charged it for a couple hours before I picked it up. put it in the next day... and nothing. I had to push start. ended up running it for a good 2-4 weeks before my bike sat for about 2-3weeks. Tried to turn it on and nothing. Took it to them, charged it till it said 100%. Put it in my bike yesterday, ran it to work, to school, and then back home tonight. Stopped to talk with the security guard so he can see my bike (will post pictures this week... hint phrase: all carbon). I left the bike on as we talked for a little, shut it off, then turned the key so he can see my tail light on without the bike working for less then a minute... get on to turn it on and go home.... you guessed it... could not turn on. :dontknow: anyone have ideas?
