Hi guys,
as I bought my first Opus I didn't know much about it, and over time I read many facts about it in different Threads. Therefore, I thought it would be nice to have all that Facts and knowledge about the Opus in one thread. So I decided to create this thread for that Info, and I will keep this post up to date with all your suggestions. So feel free to tell what you found out about the Opus.
General Info (for newbies):
The Opus BT-C3100 is a good Charger / Capacity Tester for Li-Ion, NiMH and NiCd (also LiFePO4 and LiHV) batteries (cylindrical cells, form factor: 10340, 10440, 14500, 16340, 18500, 18650, 26650, 26500 and more.)
It charges at 200mA, 300mA, 500mA, 700mA and 1A on all four slots, and if only slot 1 and 4 are used, it charges also at 1.5A and 2A.
It discharges at 200mA, 300mA, 500mA, 700mA and 1A.
User Manual
The modes are: CHARGE, DISCHARGE, CHARGE TEST, DISCHARGE REFRESH and QUICK TEST.
CHARGE TEST mode charges the cell first, then measures the capacity while discharging and charges the cell again.
DISCHARGE REFRESH mode cycles the cell 3 times, starting with discharging.
QUICK TEST mode tests the IR (Internal Resistance). This mode is not recommended because of the inaccurate readings, especially if you don't have the wire mod.
The Opus BT-C3100 costs about $30. If an offer is rated way more expensive or cheaper don't trust it!
Here's REALLY detailed review for the nerds
I just realized, that there is also a detailed Review and discussion about the Opus from rebelrider.mike

Please correct me if I'm wrong and tell me what I've missed
Cheers!

Some Issues discussed in this tread
Facts:
- Overheating pauses (Mostly happens in warmer surroundings at Discharge current >700mA)
- About 10% higher capacity readings, caused by the Overheating pauses and high connection resistance
- Inaccurate (useless) IR (Internal Resistance) readings (for accurate readings, a four wire IR tester is needed)
Functions you may not know:
- LCD backlight always on function (If you press the DISPLAY button for a two sec, the backlight will stay on.)
- Select all Slotways set the Opus on one side because that way the air can move better and mostly s (If you press the MODE button for two sec, all slots will be activated to set the mode)
Hidden / Unknown features:
- Charge end Voltage switch (inside on the PCB, (3.7V, 4.2V and 4.35V) preset is 4.2V)
- Voltage correction Jumper (If the Opus reads 50mV higher)
Mods:
Tips:
- I always set the Opus on one side because that way the air can move better and mostly it doesn't stop while discharging. (Not needed if you have the Fan Mod)
