When group 78 batteries are in parallel, their voltage is equal to the voltage of one battery, while current capacity equals to the sum of all its battery capacities. If you have two 12V lead-acid batteries with 60 Ah capacity and you connect them in parallel, you'll get 12 Volts with 120 Ah.
Bigger batteries can have more capacity and power compared to 78 batteries. If you need 24 Volts, you can connect two group 78 batteries in series to double the voltage. The voltage of a series connection is equal to the sum of the voltages of all its batteries.
Maximum Continuous Discharge Current – The maximum current at which the battery can be discharged continuously. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity.
A battery can supply a current as high as its capacity rating. For example, a 1,000 mAh (1 Ah) battery can theoretically supply 1 A for one hour or 2 A for half an hour. The amount of current that a battery actually supplies depends on how quickly the device uses up the charge. What Factors Affect How Much Current a Battery Can Supply?
(Recommended) Charge Current – The ideal current at which the battery is initially charged (to roughly 70 percent SOC) under constant charging scheme before transitioning into constant voltage charging. (Maximum) Internal Resistance – The resistance within the battery, generally different for charging and discharging.
So, yes. Batteries have a max current drain (given by design and physical/chemical limitations) and yes the storage rating (being Ah, Wh or Joules) changes depending on battery design and load applied, and yes Wh is a better way to compare batteries because it takes voltage in account.
What amp should I charge my LiFePO4 battery?
If you have a 12V 200Ah battery, the maximum charge current is as follows: 200Ah * 0.5C = 100 Amps. Now if you have a 48V 100Ah battery (5kw server rack) the charge current is the following: 100Ah * 0.5C = 50 Amps. We can see that the maximum recommended charge current depends on the battery capacity (Ah), not the voltage.
