This isn’t a review as I don’t have all the gear to properly test this but mine arrived yesterday and first impressions are it’s great.
It’s a chunky beast compared to the OPUS chargers I’ve got but the bonus is that it is nearly silent. There is a good amount of mass to dissipate heat and the only noise you can hear if the room is really quiet is the occasional charging circuitry changing.
I was charging 4 x 18650’s last night and noticed that they were all charging at 2000 (1997)mAh each. The product description shows its 3A max per channel OR 6A total output. What is going on here? Is it jumping slot to slot?
I’m tempted to get 8 cells all the same, drain them down to the same voltage then charge them all at “full speed” on the Opus and the SC4 and see which one is the fastest.
A couple of comments about the charger though are that the display is very easy to read. I was wary about the lack of information for each cell but it’s okay as you just press to jump cell to cell for more information.
The resistance check seems like a nice addition. It showed me that one of my “rescued” cells was actually knackered as I first expected.
I’ve not tried restoring dead cells but I’m hoping to find where I placed those cells in the next few days.
I did charge a 26650 cell at 3A and was pleased to see the cell didn’t get warm and over half an hour the display told me that it had charged it by 1482mA which makes sense.
All in all its a nice charger from my very limited time with it, I’m just confused about the 4 x 2000mAh being displayed yet a max output of 6A
It doesn’t look like it’ll discharge and recharge the cells. I purchased this because of the faster charge rate and the fact it is silent. Sometimes I want to charge my cells in a quiet environment and the pair of Opus chargers I’ve got are simply too noisy for that.
