What is the maximum amount of tokens to burn using TokenBurnTransaction()?

When I try calling TokenBurnTransaction() with 37 NFT serials, I get a return error BATCH_SIZE_LIMIT_EXCEEDED. I am therefore wondering what is the maximum amount I can burn within a single function call.

The maximum number of serials that you can mint or burn in a single transaction call is 10.

See this code sample:

// BURN 10 SERIALS IN THE NFT COLLECTION
let tokenBurnTx = await new TokenBurnTransaction()
    .setTokenId(tokenId)
    .setSerials([1, 2, 3, 4, 5, 6, 7, 8, 9, 10])
    .freezeWith(client)
    .sign(supplyKey);
let tokenBurnSubmit = await tokenBurnTx.execute(client);

If you inspect the mirror node REST API for the corresponding transaction, you'll see all 10 mints/burns.

REST API (testnet is reset each quarter so you may not see the exact result in the future): https://testnet.mirrornode.hedera.com/api/v1/transactions/0.0.1218-1675178140-095602422 Here's a portion of the mirror node info:
