Batteries and Battery Box
Voltage is important because the voltage of the battery must match the application requirements of the device. Voltage is simply a unit of measuring electrical pressure, and all batteries are rated in volts DC (Direct Current). Think of water flowing down a river. Voltage is how quick that water is flowing, where as amperage is the amount of water flowing. The more voltage the stronger the flow of the water. The more amperage, the more water flowing.

Battery connections
Parallel and Series connections

Connecting batteries in "Series"
doubles or adds  the voltages of the individual batteries while maintaining the same amp hour capacity providing all batteries connected are the same individual amp hour capacity
When connecting your batteries in Series you are doubling the voltage while maintaining the same capacity rating (amp hours). By connecting the negative of the first battery and the positive of the second battery. Run your negative wire off of the open connector from the first battery and your positive off of the open connector on your second battery.

Connecting batteries in "Parallel"
maintains the same individual batteries voltage while doubling or adding the individual batteries amp hour capacities  
 When connecting in Parallel you are doubling the capacity (amp hours) of the battery while maintaining the same voltage of one of the individual batteries. Connecting a lead between the positives of both batteries and another lead between the negatives of both batteries. Connect your positive and negative wires to the same battery to run to your application.

Important
When connecting batteries in a pack there are some important things to keep in mind. Don't use different battery types (chemistries) like Lead Acid, NiCad (Nickel Cadmium), NiMH (Nickel Metal Hydride) or any other when connecting a battery pack. The voltages may be different, and charge rates will also resulting in a shortened life span or possibly dangerous overcharging. Also try to match (amp hour) capacities as much as possible to avoid discharging the lower capacity battery quicker than the others as that will discharge deeper than the rest and may not be able to recover.

NOTE: These are ALL Non-Spillable, Re-Chargeable Sealed-Lead Acid Batteries. The term GEL-CELL is frequently, but improperly used to describe this type battery.
CHARGING: Cycle Applications: Limit initial current to 2.16A. Charge until battery voltage (under charge) reaches 14.40 to 14.70 volts at 68oF (20oC). Hold at 14.40 to 14.70 volts until current drops to approximately 72mA. Battery is fully charged under these conditions, and charger should either be disconnected or switched to “float” voltage.
“Float” or “Stand-By” Service: Hold battery across constant voltage source of 13.50 to 13.80 volts continuously. When held at this voltage, the battery will seek its own current level and maintain itself in a fully charged condition.
NOTE: Due to the self-discharge characteristics of this type of battery, it is imperative that they be charged after 6-9 months of storage, otherwise permanent loss of capacity might occur as a result of sulfation.
We highly recommend the R&R chargers and have used this type here for years, R&R Chargers are designed for just this purpose and battery type. With this type charger and proper charging practices these batteries give years or dependable service and maintain high capacity.
