I ordered a new battery from amazon, Tattu 1800 75c 3s, which i’ve ordered previously without issue. However this new one that arrived yesterday was not detected by the charger, or by a plug-in voltage alarm. I hooked up a multimeter to the XT60 connector and it was reading 5.3v, waaaaaay less than 11.1v nominal.
Amazon have issued me with a refund for the defective battery after speaking to them about postage restrictions (especially it being defective), and told me to dispose of it myself.
My question is, can it be rescued or not? I have a SkyRC S60 balance charger, which doesn’t show any voltage on the balance lead for this battery.
If it’s going to be a danger, i’ll just discharge it to 0v and toss it.
