Decoding it, at 02:26 the PEM was at 44C, motor at 74C, and ESS at 39C. Ambient (garage open on 1 side) was 38C.

I left it for 8 minutes, after which time the PEM was at 48C, motor at 63C and ESS at 40C. Ambient was 39C.

I tried increasing current to 13A (again 220V, range mode), and left it for a while.

After 21 minutes, PEM was 48C, motor was 51C, ESS was 37C and ambient was 47C. That is a total of 29 minutes so far, and I've managed to cool the ESS 39C->37C, but heat up my garage 38C->47C.

I restarted the range mode charge at 10A and this time left it for about an hour. After that, PEM was 46C, motor 42C, ESS 39C, and my garage a blistering 59C.

This pretty much recreates my experiments from last summer. After more than an hour, the ESS temperature was unchanged, but I had managed to heat up my garage from 38C to 59C. Not sure if the term 'cool down' is appropriate for this :-(

Does any of you do cool down regularly (manually, or with Tattler)? If you do, what settings do you use (voltage, current, duration) and what sort of temperature drop on the ESS do you see?  Last year, it was suggested I try at a higher current, but that seems to defeat the purpose. Any suggestions?

Regards, Mark.
