I have bought one self heating 100Ah directly from https://ca.litime.com/ website some time in November 2023. On Nov 23 I received an email from UPS with a scheduled delivery date for Nov 24. And this started a string of rescheduled deliveries. It is today Dec 7, 2023 and the battery has still not arrived. The only thing that arrived is another email from UPS saying the battery will be delivered...tomorrow. I have sent emails to support.ca@litime.com and service@litime.com and received no response. The worst experience ever.
