I build full scale military and commercial flight simulators for a living. Safety is of paramount importance and for the most part cost is no object and every conceivable permutation of how the user can screw up the system is taken into account. Somehow, however, they still do.

Obviously I am not excited about getting the dreaded "connection breakdown" and I hope I never do. In the mean time potential buyers are being "scared" into purchasing other products that are more than likely inferior to the iCharger line.

I doubt my Hyperion Duo is inferior to it, nor my Thunderpower 610C.

I don't think there is any analogy between your "market" and this one, and I assure you that you will get the "connection breakdown" error: it is just a matter of time, in my mere opinion.

I think reasonable people can disagree about this sort of thing, but many of "us" have far more experience with this line of chargers than you appear to have, thus I believe "our" opinions are weightier.

I, too, was fat, dumb and happy for many months until the error popped up without warning, spark, no spark, or whatever.

I'll offer my opinion, again: less sophisticated users are likely willing to "pay more" for a superior, tinker-free product-I have in the past and I will in the future.

I, for one, made my purchase decision "primarily" on the experience of "Julez," who, ironically seems to have had a few issues of late and so far has kept silent on whether he would buy an Icharger, again, either intentionally or otherwise.

I'd find the opinions of "early adopters" of great weight while I sit here on the fence, waiting for Junsi to comment on or cure "the problem."

One last comment: "scared" implies a non-fact based, mere fear for one's decision, and, clearly, the "facts" are "out there" to support one's buying decision, pro or con.

Yes.. but i meant there is no word or advertisement as it is a Meanwell, Mean Well or MN power supply. It is just a 350w switching PSU.

Edit : forgot to add the photo

This way I will not stress the charger and it is easy and inexpensive to adjust the load (use your halogen lamp)

I redraw the circuit, it is easier to understand or see what is happening :
hm... i'm almost dumb in circuitry need an external help

I did send it to Shenzhen Junsi Electronic Co to get my 1010B+ fixed. Cost me AUD $40 + .. for the Aussie post..

Ah well we shall see how long this will take..

I maybe better of buying a 208B+ and charging my 5S 5A in parallel?

Anyway happy flying to all
I was told by the factory that they would exchange my 1010B+ as mine is burned beyond repair. That is good news. Hopefully I'll get my replacement before Christmas.

Happy charging to all

IMHO I believe this is why ichargers are the best. If the vendors didn't believe their product was good then they wouldn't support it. I have been following this thread closely and it seems that the vendors and distributors are more then willing to repair or replace the icharger line.

I use this power supply to the charger:
https://www.soanarplus.com/getProduc...?prodId=MP3802

I set it up at 15 volts.


All my batteries uses 5.5 mm bullet connectors.
http://www.hobbycity.com/hobbycity/s...0_pairs/set%29

I use Deans only for low current Rx batteries (2S 2.2A) and Tx batteries (3S 1.050A)

I made a 10cm (3.9 inches) 10 AWG link between the charger main outputs and the batteries. This to insure a very low resistance between charger and batteries.



I always balance charge (Setup to always) all my Lipo batteries.

I shall definitely follow the power up procedure:
1) Power up the charger.
2) Connect the balance port
3) Connect charger positive output to the battery
4) Connect charger negative output to the battery.

When my 1010B+ went "poof" smoke plus flames through the fan, it was charging 10S @ 5A for more than 20 minutes. (Logview didn't show anything out of the ordinary.) Was running 3.1 firmware version before the event.

Happy I was near the "event" and was able to stop the all process.

My 106B+ never gave me any problem. So I continue to use it waiting for the replacement 1010B+ to arrive from shenzen

question:

The input of the charger has 14 AWG 600mm (23.6 inches) long (including the 3.5mm banana plugs) cables.

Would it be better to have, on the charger inputs, shorter bigger wires? Say 100 mm (3.93 inches) 10 or 12 AWG?

Thank you in advance for your comments.
(I don't want to repeat the "smoke" event) so any good advise will be followed

I understand that you should not have to have this problem in the first place and junsi has admitted that there needs to be a firmware upgrade. If I get the dreaded connection breakdown my only hope is that my vendor does the same for me. I got the icharger because it was the best charger I could get for the money.

And, David is still the best for the money, too, but a perfect seller can't compensate for an "imperfect" product. Just my opinion.

I appreciate your opinion on the icharger, but please give your comments a rest. I've been watching the thread and you seem to reply to everyone's post.

By the way, I had a multiplex ln-5014 charger stop working earlier this year. Maybe it was my fault, but I don't recall doing anything to hurt it. I called multiplex to ask about repair cost and found they had a 2 year warranty. The charger was fixed and shipped back to me at no cost (and I didn't have to provide the receipt). Only cost to me was shipping of $5 or less to get the charger back to them. So it surely isn't only ichargers that stop working. It appears the ichargers are being repaired or replaced when they break so what more could we ask for besides a quicker and cheaper way to get them back for service?

I would say a more reliable charger, but that would be a comment.

In general, yes.

AWG 14 = 2.525 mOhm/ft => 5mOhm for 600mm
AWG 12 = 1.588 mOhm/ft (40% less resistance) => 3mOhm for 600mm

Assuming you are drawing 25A the difference in voltage drop is 50mV and power loss in the wires is 1.2W. Not a big difference but something to consider.

In this instance the vendor is Shenzhen Junsi Electronic Co.,Ltd.
I like dealers like hobbycity when they say: We shall sell product directly from manufacturers to you. No intermediate will be accepted.

For once profit goes directly to the manufacturer and one dealer only.

The internet advantage shows that intermediate(s) take a large profit and do nothing for the product or for the modeller.
Removing intermediate(s) help more people getting into the hobby as goods are more accessible (20 to 145% less expensive).

That's my opinion, and I know that many like the shop at the corner where they can "buy on impulse" at two three our four times the real price.. That's fine for those who can afford it..
Truth of the matter, they are not the majority in our little village called "earth"

Happy charging

My own plan is to power off the charger after any charge is aborted by the charger. But if a charge completes or I end it with the stop button I won't power cycle it.

With many devices cycling power adds to their wear and tear. I don't know this is the case for this charger or the P350, but it is possible. I'd hope that one could cycle the power on them many, many thousands of times before causing harm. But without the insights of the designers or lots of accumulated test data we won't know.

Finally, it is perfectly ok, in fact recommended to have the charger powered on before making connections to a battery.
Thankyou Speedebikes for that thoughtful response. I think what you are saying is quite sensible and I appreciate your insight.

An update to my 208b problem. Amainhobbies support took care of me. They seem to be taking care of handling iCharger issues directly which was a relief. I was able to send it in to them. I was afraid I would have had to send it in to China.
