Yes, I doubt the charger is using -dV to terminate my old NiMH cells. But they do eventually terminate, after putting about 2x more energy in them than they have in capacity. I suspect the charger must also terminate at some fixed voltage, if it doesn’t detect a -dV signal.
I do sometimes just remove the cells when I see the voltage has risen to about 1.55v. Since they old and worn-out anyway, I don’t really care if I’m damaging them by overcharging. I just like the fact that the old Li-500 charger has a 300mA setting so I can actually charge them.
I really do like the display on this model but I have a ton of charges that fill this niche. Maybe I will pick one up later when they put them on sale without the power supply at the $15 to $16 range. I mean I like the display but I’m not going to look at it very long anyway. Great buy for those whom need a good charger though. I would buy it if I needed it.
You see, charging NiMH cells is about as efficient as lithium-ion cells up to 70% capacity filled.
However, close to full, it goes down to around 60-70%.
0,5C is about the best current to charge any NiMH cells.
Low enough current not to produce too much heat, but high enough current to just produce enough heat for the charger to detect the voltage drop due to the heightened internal resistance.
Some chargers are very good about it, like my MiBoxer C4-12.
Why do some people feel they’re so special they have to continue to post the same thing over and over again in an unrelated thread? Like their opinion is gold and is more important than others…
Like beating a dead horse. Glad you got something that works for you and you like better, this is a group buy thread for a great charger at a great price, can we PLEASE stick to discussion of this charger???
Its like this in every thread he posts in! For someone who doesn’t have time to put 4 buttons they sure do have lots of time to post the same thing over and over again… Get a life man, glad your happy with the product you have and use, that’s great, but lots of people are happy with other stuff and don’t necessarily want to hear about your choices in every thread [not] on the subject. Talk about a time waster.
Yeah, it seems the most expensive shipping pops up as the ‘default’ now… it was $13.65 to Alabama. :person_facepalming:
Of course I quickly found the cheap0 option…. $1.30 just like yours Theodore…
I guess they are hoping some people won’t take the time to change it….
Also, this time I had to add “+001” in front of my phone number to ba able to place the order. That has changed since the last time I ordered something.
Either way the order is placed. :+1:
Hopefully it will ship close to the projected fulfillment date of 18 June.
Dang,
Hope it wasn’t me. I’m offended that everyone is always offended about something. I bet someone owes me something for something. Now I’m angry. See how this works.
Just to stay on subject so I don’t get my face bit off. I really use my Lii-500 a lot. I have 2 of them. With the couple of added features on the new unit, it will make this a very popular charger especially for the price.
I ordered the 500S based on the information on the Liitokala website that indicated it did include the 300mA charging current option, like the old model. I later emailed Liitokala to ask if that information was correct, when I found the instruction manual and saw it did not say the 300mA option is available in the new model. The answer from Emily indicates they eliminated the 300mA option.
I was at first upset about the incorrect information on their website, until I realized that my 16340 cells have between 650 and 750mAH capacity, and my AAA cells have a minimum of 750. A 500mA charging current will be fine for those cells, and I’ll charge my 18650’s at 1A. The cell manufacturers say a quality cell will remain perfectly healthy and maintain its full number of charging cycles when charged at up to 0.8C in a quality charger, and even above that rate in most cases. I don’t think I need to worry, given that 500mA will be below 0.8C for my smallest cells, and I don’t re-charge my small cells often. And this charger has very good over-heating and over-charging protection, as well.
Warning: off-topic, but still relevant to BG purchases.
Yea, I’ve noticed this new “behavior” just over the past week or two. It’s ridiculous and probably not even profitable, since it gives customers a shock when they see the checkout price and they may simply cancel the order out of annoyance.
I added a $12 item to my cart and the default shipping charge was over $14. Do they think that such a tactic will sell more products? I felt slightly angry and highly insulted, which I wouldn’t consider to be an effective business strategy.
This is hopefully a programming or configuration error, but if not then it’s just Banggood being Banggood.
