Every 100 kcal of lotus seeds brings 4.6 g of protein. On that measure it ranks 9th of the 27 seeds in this database and 489th of all 796 foods on the site. Measured by weight instead, its 15.4 g per 100 g ranks 25th in its group.
Around 19% of the calories in lotus seeds come from protein, so it is more of an energy food than a protein food. It contributes to a day's protein total, but the bulk of what it delivers is energy rather than amino acids - treat it as a contributor alongside a denser source, not as the protein in a meal.
Weight for weight, lotus seeds has 7.8 g of protein for each gram of fat (15.4 g against 1.97 g per 100 g).
Set against flaxseed, another seed entry in the database, a serving carries about 0.5 g more protein (flaxseed has 3.8 g per 2 tbsp).
It is an incomplete protein on its own; pairing it with other plant foods across the day covers the full range of essential amino acids. The serving quoted here is measured by weight at 28 g, and it covers about 9% of the 50 g FDA Daily Value for protein.

Sample figures for one made-up week against a 110 g goal, not your data. Red bars met the goal. Your own log fills this in with Premium.
15.4 g. The 1 oz serving used on this page weighs 28 g and so carries 4.3 g.
How much protein do you get per 100 calories of lotus seeds?
4.6 g. That figure divides its 15.4 g of protein per 100 g by its 332 kcal per 100 g, so it does not depend on serving size.
Is the protein in lotus seeds complete?
No. On its own, the protein in lotus seeds is short of at least one essential amino acid; other protein sources across the day fill the gap.
What share of the protein Daily Value is one serving of lotus seeds?
About 9%. One 1 oz serving has 4.3 g, and the FDA Daily Value for protein is 50 g.
