I bought 3 Ampre Time (now Li Time) in Jan 2023, all have died for various reasons and different times. They replaced with two Li Time. I have been running one of the two for 3 months no problem, I just got the 2nd one back. The third has since died.

What i will say is if you have a battery go bad, you will be speaking to someone in China to get a replacement. It takes days to get a response, multiple excuses, to finaly get a replacement. Taken well over a month to get a replacement for the first two AmpreTime from Li Time. Add this headache i just don't know if hooking and unhooking batteries, long waits to get replacemnt is it worth the cost savings on intial purchase
