It depends on the battery. With a 6-cell battery pack it goes about 25 mph, but with a 7-cell it reaches around 30 mph. www.traxxas.com
Check and see how many Ah (Amper hours) your battery is. If it is for a gas/gasoline car, then it is probably around 42 Ah; batteries for diesel are usually around 72 Ah. Check the power of your battery charger. It should be something between 4-6 A. You must divide the battery capacity by the charger strength to get the time necessary. For example: your battery is 42 Ah and your charger is 6 A. Then the time needed will be 42 Ah / 6 A = 7 h. Charge your battery no longer than 7 h. Please note that overcharging the battery permanently damages it.
No, the Nexus wireless charger does not have an internal battery. It requires the micro USB charger for it to wirelessly charge a Nexus 7 (or Nexus 4 or 5).
The main battery pack (behind the rear seat) should last for 12 - 15 years. The Prius battery pack is always charged above 70% of max and because of this lasts longer. The small ordinary battery that powers up the instruments should also last longer than in other vehicles. This should last over 7 to 8 years. The small battery only powers up the instruments, it is not used to turn over the engine. Actually the Prius battery can last 13+ years as it has already been proven (13 years in production, with relatively few problems). Japan was the first country to get the Prius, in 1998. According to Toyota the battery charge is kept constantly between a 45% charge and 75% charge. The charge indicator is 75% charge at max, and 45% charge at min. (which is never reached in practice). It likes to stay over 60% charge.With this approach the battery never over charges or under charges. Kind of like your cell phone, which is a lithium battery but same principal applies. We let our cell phones die then we plug them in before we go to bed. So the cell phone battery goes from no juice to being over charged, which over time kills the battery sooner. Cell phone companies tend not to talk too much about this as it adds added sales in batteries every 1-2 years.
