Thank you and  absolutely on the heat resistant surface 

[Need help sizing resistor]

K so I don't know of any one doing this but I am going too. I am making a battery pack (don't worry not my first time: and I will be using A external balancing charger) but have never made one for a DNA 250 and need to sync the discharge profile to the pack so it runs properly

Yes it's for a battery analysis test so I orders 2 - 1 ohm 50 watt as seen on another set up on u tube i will wire to  parallel I have nothing for a cooling plate but I have a fan what would you suggest for a test wattage setting in open air

Need help sizing 40w resistor I could use more information like how many K (eg. 30k-80k??) or a link to one at  Amazon thank you in advance
