I had a problem with the battery and / or chareger for my golf trolley..the battery was showing no charge at all. I know it was during lockdown but I sent 3 emails and got no replies. I tried phoning and kept getting put to the back of the queue and didn’t get to talk to anyone. A few days later I got through to talk to someone who said that someone would call me back after July 4th. On contacting a lithium battery company I was told that there was a chance that the battery would explode, it does happen.
So I scrapped the battery and am still waiting to be contacted.
