45c heat and my cells in the back shed - all ok!

[3nergE]

Just did a quick vid that shows even in the 45c heat, my cells are sitting nicely at only 46c.

I think 1c above ambient is just fine, no fans, no inso in the shed.
This is during a charge cycle in the middle of the day.
Totally not stressed about the heat, it may get a few degrees hotter here this summer, but this is a non issue for me.

I just checked out your video and subscribed

Your cells look like they all have decent mAH, did you get them new or used?

Got my cells used for most of that build.

BUT, i have recycled new replacment batts, the chinese 1800mAh cells inside usually cap test out to about 2000-2200mAh and at about $2 per cell, well, its worth it either way.

kind regards

Thanks for the info I think my laptop batteries are pretty old, they don't seem to go above 1700mAH, most around 700-1200. Though I have had them for around 10years, some longer, sitting in boxes...

I pulled appart a makita drill with 10yo cells, all cap tested out to 500mAh, 10 YEARS!

Mates dad was a builder, he used em everyday - poor cells. No idea what the original capacity was, cant imagine them being more than 1500mAh from back then.
