Умное зарядное устройство Opus BT-C3100 V2.2

Показатели напряжения теперь обновляются каждые 30 секунд, что в 2 раза чаще, чем в предыдущей версии.
Исправлены неточности в показаниях мАч на некоторых Li-Ion аккумуляторах (в частности Panasonic NCR18650B, NCR18650PF). Для этого максимальная амплитуда напряжения при заряде была снижена с 5В до 4.65В).
Улучшена работа алгоритма измерения нагрева платы контроллера. Устройство, с помощью кулера, теперь более эффективно поддерживает оптимальную температуру, не допуская перегрева, что особенно важно при заряде/разряде Li-ion аккумуляторов.
Погрешность измерения силы тока во время заряда/разряда снижена с 5% до 3%. Точность замера напряжения аккумуляторов также повышена.
Удалена функция предварительной зарядки с помощью импульсного тока. Сделано это для предотвращения зарядки при неправильной установке аккумулятора в слот. Ранее, устройство определяло перевернутую батарею, как имеющую напряжение в 0В (т.е. полностью разряженную и требующую предварительной зарядки) и начинало ее заряжать.
Добавлена функция автоматической подзарядки для Li-ion аккумуляторов, устраняющее проблему разряда батареи после полного заряда (через устройство, а также из-за саморазряда). Подзарядка активируется автоматически при снижении напряжения в аккумуляторе до 4.12В.
Уменьшен нагрев Ni-MH аккумуляторов во время зарядки.
Время полной зарядки 4.35В и 3.7В аккумуляторов оптимизировано. CV режим зарядки для таких батарей теперь стартует при напряжении 4.26В и 2.8В соответственно.

Backlit screen (will turn it off after 20 seconds)
Backlit can be turned on permanently by pressing "DISPLAY" for 3 seconds.
Charges Ni-Cd, NiMH and Li-ion batteries.
Rubber feet.
Approx. 3/16" bottom clearance
6 internal temperature sensors.
Small fan to exhaust heat.
Fan noise has been improved from previous version (BT-C3100 V2.1).
Excellent build quality.

Has 5 MODES:
CHARGE, DISCHARGE, REFRESH (DISCHARGE REFRESH),
TEST (CHARGE TEST), QUICK TEST.

CHARGE:
Charges battery to maximum capacity.

DISCHARGE:
Discharges battery. Reduces the memory effect in the battery.

REFRESH (DISCHARGE REFRESH):
Discharges, then charges battery 3 complete cycles to optimize it's
maximum capacity.

TEST (CHARGE TEST):
Checks the capacity of the battery.

QUICK TEST:
The charger checks the dynamic internal battery resistance.
Consult manual for further details.

This is an excellent, fun, easy to use, charger, that gives you total control of how
you want to charge and maintain your batteries. A big plus is the ability to get the
capacity of the batteries. The fan noise is considerably less annoying than the one
on the V2.1 charger, IMHO. This charger is a great companion to my XTAR VP2.

GearBest got it to me, fast!!!
Thanks!!

This charger meets all my needs:
It has a single channel charge, that is, you can upload an unlimited number of batteries, so that only one, two, three or all four simultaneously. This is important for me because I have a number of devices that only need a battery or three.
Ordinary charger can only pairs (ie 2 or 4 at a time) load.
You can combine the types of batteries colored, so you can simultaneously charge different capacity NiMH batteries and lithium ion batteries.
Each span can individually adjust the charging current and the function.
Functions dominates the charger following:
* Download (Sure)
* Exhaust (in order to avoid any memory effects with NiMH)
* Refresh (charger repeatedly discharge and charge cycles until improvement in battery capacity you get more. So you can old batteries, or those who have long remained, still breathing a little 'life)
However, Opus can also deal with Li-Ion batteries, and I have the chance to request a particular device in your home. Moreover, the battery of tests (measurement of internal resistance).
I hardly use this feature however.
A fan, the device is also to cool the batteries, which should become warm during charging. I was able to observe that the fans have already activated, very hot but the batteries were not.
Conclusion: excellent charger handyman.

Chargeur universel intelligent livré dans une boite en carton avec une notice d'utilisation et un adaptateur EU.
La finition du produit est correcte mais le plastique pas assez costaud pour lui offrir une
résistance aux éventuelles chutes.
A part ça, ce chargeur est intéressant du point de vu de ses possibilités et de son prix.
Durant le chargement, le ventilo, de temps à autre, se met en marche et se fait entendre pendant quelques secondes.
Globalement satisfait on verra dans le temps.

This Opus version comes in a nice carton box with EU adapter and an operating
instructions notice.
Charger build quality is correct but plastic material is not strong enough in case of drop.
Easy to start and use.
One can easily follow charging phases individually and adjust features using different mode.
Charging time is quiet fast.
While charging fan become noisy for a few seconds (time to time)
For now satisfied hope it will last.
Last Gearbest price for this item is very competitive

Bought it as a replacement to my 1st version of bt-c3100 by powerfocus that broke after inserting the battery in opposite way.
It does much better job: you can top up battery that has for instance 4.16V - while previous version just notified about full battery
It is much less obtrusive less noise from the fan, which works quieter and is on only when required.
It does charging in some different way, battery that is old and has high internal resistance charges with smaller current, ends of charging cycle with smaller current than previous version of the charger
Can charge two battery with 2A while previous version often just reset itself upon choosing 2 slots with 2A charging
Overall I am very very happy about purchase, one can experience that this one is just better more refined device than previous one, however in the meantime I have notice there is new more advance charger available here - unfortunately
The price here is the best I have came across by 30% than somewhere else!!!

I wish it be able to charge with 3A....
1 month in transit (but its my fault I have chosen Nederland surface post)
