Default 4.5 hour charge time???

I am looking into buying a Sensei. The Sensei site stated that it takes 4.5 hours to charge the battery. Is there a faster charger available, or are they all going to take this long?

Thanks!

The included charger's max rate is .8 amps.
Safe charge for the pack is 1C rate or 2.1 amps

So yeah it's going to take that long as the charger is such a low rate.

And yes you can buy a better quality charger that will safely charge the pack a 1C or 2.1 amp rate.
But just so you know, even at that, a fully depleted pack will take an hour or so to charge.

Thanks GG. Just what I wanted to know. I didn't think it would take that long or everybody would still use gas.
