How do pass large number to deploy in hardhat?

This is the error I get:

Error: overflow (fault="overflow", operation="BigNumber.from", value=3.96e+26, code=NUMERIC_FAULT, version=bignumber/5.5.0)

  reason: 'overflow',
  code: 'NUMERIC_FAULT',
  fault: 'overflow',
  operation: 'BigNumber.from',
  value: 3.96e+26

Here is the code:

  const decimals = 18;
  const supply = 396000000 * (10**decimals);
  const fee = 50;
  const feeTaker = '0x00';
  const maxSupply = 1000000000 * (10**decimals);
  const HuskoToken = await hre.ethers.getContractFactory("HuskoToken");
  const huskoToken = await HuskoToken.deploy(supply, fee, feeTaker, maxSupply);
  await huskoToken.deployed();

Hardhat handles it by default with ethers this way

const maxSupply = ethers.parseEther("1000000000")
