First signs of throttling…. 10 minutes into charging, the charge rate dropped to 215 watts. Battery cell temp remains 113°F. ---

It’s been almost 1.5 hours now, and Yarbo is still charging, albeit at a reduced rate. Ambient temperature is 96.8 degrees Battery cell temperature is 120.2 degrees Charging power is holding steady at ~225 watts Charging is slower; we’ve gone from 29% to 56% in the last 1.5 hours. But Yarbo hasn’t stopped charging (yet). So far, so good. I guess I should specify - Yarbo is 100% stock, with no modifications for cooling. Only the fabric dog shelter and the dock being on a shaded part of the property. ---

Is yarbo’s diagnostic page temps in C the same as the temps you see in HA? ---

Yes, matches perfectly. showing 49C in the diag screen, which equals 120.2F which is what I’m seeing in HA. Keep in mind, there are 6 cell temp readings in HA. I deliberately chose to monitor the one that tends to register the hottest. ---

Ok. End result: Yarbo’s battery never overheated, but the charging curve was throttled about 10 minutes into the charging cycle. The charge rate never went back up. As a result, it took about 3 hours 40 minutes to go from 29% to 100% charge. Battery never got hotter than 120.2°F. ![IMG_0236](https://canada1.discourse-cdn.com/flex007/uploads/yarbo/original/2X/0/05fc1b4158dff3a2a4c9ec19e43ee0134380b7ee.jpeg) ---

Yarbo can’t cut no 6 acres taking that long to charge. Yikes ---

Yea, the reduced charge rate kills productivity. Need to have Yarbo start very early in the morning in order to get 2 cutting sessions done before end of day. At least charging didn’t stop completely. But charging time is roughly doubled. ---

That does not work for me cutting early as the morning dew lasts till at least 11am most days, and then sets back in after 7pm, short window here. I wish they had a summer battery. Speaking of battery I saw a post that Yarbo figured something out so 4 hour battery pulls might be ending. ---

Yep - that is good news. ---

Is the temperature information posted in the wiki still accurate? I mowed today. The battery temp was 45C at the end of the mow. I just checked it and it’s reporting 55C battery temperature. It was still charging with no over temp warning. Per the wiki, it should have stopped charging. ---

Should still be accurate, but that temp reading is only from one of 6 sensors. It may even average them. But it doesn’t show that it stopped charging in the app view. Only in diagnostics or charging status light on the dock would make it apparent. ---

I really think Yarbo should be comping the Core Skin, since it’s not going to be able to finish a big yard in a timely manner in this heat. [Previous page](https://forum.yarbo.com/t/yarbo-and-the-heat-wave/6764.md?page=1)
