It was a low charge start, I think it had 1 bar left on the battery. The temperature of the charger jumps up within minutes and gets hotter as it runs, but it seems to taper off with time. I doubt it would get much hotter until it finished charging, I assume it is easier to finish off charging rather than starting from flat. I won't alllow my electronics to cook, however I normally don't worry about electronics getting warm unless it is too hot to comfortably hold, around 60C. I've charged 4 batteries one after each other with this, as well as parallel charging a battery and the R/C, even though it's not recommended. The charger didn't feel much hotter. The charger is always warmer than the batteries, although with a greater thermal mass they will tend to retain their heat for longer, whereas the charger will cool quickly. I find that if if I leave a few inches clear around the items, that is enough to dissipate any excess heat. The 100W charger supplies more current so the battery will charge faster and that may generate more heat. I've also hooked up 3 batteries and a R/C on a 3-way power splitter so they were all charging at the same time. The charger didn't seem to get much hotter (though it did take much longer), which leads me to suspect the charger will output it's rated power and the batteries will draw whatever is available and charge in their own time. The problem with this approach is that the charger is outputting its rated output for many hours without a rest, which may exceed its expected duty cycle of about 1 hour. |
