1 This poses a problem for locating a vertical stabilizer and may result in very large vertical surfaces. ( 2 Note, however, that winglets may be used to advantage in this case.). 3  Wing twist distribution is strange and C L dependent: The wing additional load distribution is distorted by the canard wake.
Generally speaking there are two different types of lead acid battery, Starting and Deep Cycle. If a starting battery is routinely deep cycled (discharged below 20%-50% of max capacity) it will generally fail after 30-150 cycles. The same starting battery will last for thousands of cycles if it is just used normally (2% - 5% discharge).
Marine or deep cycle batteries are used for things like trolling motors and golf carts which may take tens of amps on and off for many hours in a days use before being recharged once.
