Hi!
I’d like to buy a Opus BT-C100(one slot) in order to charge and measure charge of my 21700 and 1.5v li-pol AA
I’ve already seen that people in the Internet wrote that that Opus doesn’t have a reverse polarity protection.
I cant believe that such devise doesn’t have so important protection.
Does Opus BT-C100 have a reverse polarity protection?

I stayed up too late, trying to get internal resistance numbers for the batteries I bought online that I believe are counterfeit. I was comparing them to my real 30 Q’s, and I somehow absentmindedly put one in backwards it took me a few seconds to realize when the display did not light up correctly on that slot. I also noticed a bad smell and a small amount of smoke came out of the charging Bay from underneath the battery inside of the charger. Bay one seems like it is always getting power now, …
Its possible the new ones are updated, not sure.

Thanks, but I asked about the model with one slot — Opus BT-C100

Yes, I’d seen that article before.
Some time has gone since that post was made and I think there may be a new edition of the device.
A lack of RPP in the device is nonsense to me.
This device is obsolete and expencive. Just get some new one like LiitoKala Lii-PD2

The first that I need — is testing. I need to know how many mAh I can get from my batteries.
Does Lii-PD2 have a discharge mode?

You could just go ahead & get the OPUS BT-C100 & be super careful so as to not make a mistake.
It is not that hard.

The best reverse polarity protection is being extra careful. The same way you don’t put your car in reverse while driving forward.
