How to write 5000 records into DynamoDB Table

Question

I have a use case where I have to write 5000 records into the dynamo DB table in one shot. I am using the batch save API of DynamoDBMapper Library. it can write up to 25 records in one go. can I pass the list of 5000 records to it and it will internally convert them into a batch of 25 records and write to the dynamodb table or I will have to handle this thing in my code using conditional some logic and will pass only 25 records to batch save?
