Opus BT-C100 reverse polarity protection

Hi!
I’d like to buy a Opus BT-C100 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?

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.

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.
