What are deep cycle batteries?

Deep-cycle batteries typically feature thick plates with a high-density active material. The thick battery plates allow for reserve energy to be stored deep within the battery plate and released during slow discharge such as trolling or electronic instrument use. The high-density active material remains within the batteries' plate/grid structure longer, resisting the normal degradation found in cycling conditions. They are typically used where the battery is discharged to great extent and then recharged such as a battery powered trolling motor on a fishing boat.

How can batteries be connected?

Note: When interconnecting batteries (cells), they must be identical in voltage and amp rating! 

Batteries may be connected in series. The positive terminal of the first battery is connected to the negative terminal of the second battery; the positive terminal of the second is connected to the negative of the third, and so on. The voltage of the assembled battery is the sum of the individual batteries. The batteries are connected: + to - to + to - to + to -, etc. The capacity of the battery is unchanged.

Batteries may also be connected in parallel. The positive terminal of the first battery is connected to the positive terminal of the second battery, the positive terminal of the second is connected to the positive of the third; the negative terminal of the first battery is connected to the negative terminal of the second battery, the negative terminal of the second is connected to the negative of the third and so on. The batteries are connected: + to + to + and - to - to -. In this configuration, the capacity is the sum of the individual batteries and voltage is unchanged.

For example, (5) 6V 10AH batteries connected in series produces a battery array that is 30 Volts and 10AH. Connecting the batteries in parallel produces a battery array that is 6 Volts and 50AH. Ordinary auto batteries are designed in the same fashion. Six 2-volt cells are arranged in series to produce a 12v battery.

串联冗余配置有时也称为“N+1”系统，不过，它与通常悄况下用N表示的并联冗余配置截然不同.串联冗余设计概念既不需要并联总线，也不要求模块的容盆必须相同，甚至不耍求模块来自同一个制造商。在该配置中，正常情况下由一个主要的或主UPS模块为负载供电。同时.一个串联的或辅助的UPS为主UPS模块的静态旁路供电。该配置要求主UPS模块的静态旁路具有单独的输入电路，这种方式可以在保留现有UPS的情况下.对之前的无冗余配置进行扩充，以获得一定程度的冗余。

　　

　　在正常运行条件下，主UPS模块将承担起全部关键负载的供电，串联模块不承担任何负载。一旦主模块负载转换到静态旁路上，串联模块将即刻接受主模块的全部负载.因此，必须仔细选取串联模块，以确保它能够迅速承担起负载。如果它不能完成该任务，它自身或许可以转换到静态旁路，但这样一来，便使得该配置方案所提供的冗余保护消失殆尽。

　　对于这两个模块而言.只需将负载转换到另一个棋块，便可轻松提供服务。由于输出线路仍存在单故障点，因此，维护旁路仍然是一项重要的设计功能。整个系统每年需要停机2-4小时，以便对系统进行预防性的维护。虽然该配置方案的可靠性提高了，但往往却被开关装置及相关控件的复杂性所抵销。
