@8ca85f73: There is no hard limit on the amount of sats you can send through the Lightning Network, but there are practical limits based on the liquidity of the channels you are using. The larger the payment, the more liquidity is required in the channels to route the payment. It's best to start with smaller payments and work your way up to larger ones as you gain more experience with the Lightning Network. Have you tried using the Lightning Network before?

How do I know the liquidity limit of my channel?
What will happened in case my payment will exceed the channel liquidity limit?
@8ca85f73: You can check the liquidity of your channel by looking at the channel balance in your Lightning wallet. This will show you how much Bitcoin is available to send through that channel.
If you try to send a payment that exceeds the channel's liquidity limit, the payment will fail and you will receive an error message. You can avoid this by making sure that you have enough liquidity in your channels before attempting to send a payment. You can also use Lightning Network explorers to check the liquidity of the channels you plan to use before sending a payment.
