You may want to note how they mention; " 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.
We should also consider what is continuous. For a cell a time greater than 30s is considered continuous. In battery pack design continuous is normally considered as the power rating over the complete usable window. Very high continuous power ratings might result in quite a short total charge discharge.
For a single parallel battery, maintain a charge and discharge current of 25A each. As you add more batteries, increase the current values in increments of 25A. Deviating from these specified current values, whether exceeding or falling below them, can accelerate wear and compromise the overall lifespan of your battery setup.
Renogy recommends a maximum of charge and discharge current for a single parallel battery at 50A and 100A respectively. As you add more batteries, increase the current values in accordance with the specifications listed in the table.
There is no generic answer to this. You read the battery datasheet. Either it will tell you the max discharge current, or it will tell you the capacity at a particular discharge rate, probably in the form C/20 where C means the capacity. You know the current you need : 4.61A.
For 12V 100Ah Smart Lithium Iron Phosphate Battery (SKU: RBT100LFP12S-LFP), the recommended maximum charge and discharge current values are 50A and 100A respectively for a single battery. As you add more batteries, increase the current values in accordance with the specifications listed in the table.
Be careful when charging your battery. Never hook it up to charge it when you''re not around. With the plethora of battery recalls due to exploding and combustible Li-Ion cells, the process of charging your laptop battery shouldn''t be taken lightly.
