As a general rule, the maximum charging current of a battery is around 10 to 20% of its entire capacity. For example, if you have a 12V lithium battery with a capacity of 100 Ah, the maximum charging current should not be more than 20 Amps. It is better to speak with your supplier to determine your batteries' exact maximum ampere rate.
