Perfect. Thanks!

thanks for the reply. any ideas why the pc power supply is cutting out when the voltage peaks? i have tried charging at 0.050A, the lowest setting, and i get the same result.

I saw that earlier tonight as well.

Tried different browsers and devices and came up with the same.

I'm sure Dale will have it fixed soon.

They are not designed with quickly changing loads in mind. Other problems are reported too, like overcharging: http://www.rcgroups.com/forums/showp...ostcount=10374
Look at the graph representing input voltage.

Does the charger do this when powered by a battery?

I found Q26, but I can't seem to find D16. It isn't under the LCD is it? Edit: Found it

Edit: Is this the one people are using?

And is this Q26? Is the package SOT-323? Or SOT-23?

Edit: Got the back off and it looks like U8 is a goner. Is it worth pursuing a repair, Junsi?

3.14 : charger simply reboots with the error message and hangs (push buttons don’t work)
3.12,3.13: charger doesn’t reboot, the buttons and menu work, but when trying to start charging, after “Battery Check, Wait Please”, I get “ERR: FLASH Memory” again.
Sorry for the trouble caused, please check the PM we have sent, thanks for your cooperation.

306B -- First Impressions

Just unboxed the 306B. Wow, it looks great. The way form follows function is fantastic: (heat dissipation). Feels like the way they used to make things back in the day, original old school. I sure hope the performance lives up to the first impression: (I'm not turning it on until I've read and understood the manual). Being brand new to advanced power management and all. I don't like unexpected sparks, brown outs, or 'lil puffs of smoke and acrid smells. I don't love the smell of circuit boards burning in the morning.

I would like to know. Is the USB socket on the 306B supposed to be shallow with zero ergonomic feedback? I sure hope so, because it would be brutal to get the one 306B that has a wonky USB socket.

Just a heads up and yes I knew better but forgot.

I have been using my 306B to parallel balance charge 4 each 300 mAh 2S Lipolys for my Blade 130X and today they seems a bit weaker than normal. I decided to check them on another charger and found that they were indeed out of balance by 0.3V which really surprised me until I checked its' setting and found that I had left it set to Balance at CV stage. 4 LiPolys of 300 each equals 1.2Ah and I charge them at 2 to 3C so 2.4 to 3.6A and it turns out that the 306B's balancing power just is not enought to balance these mixed packs during the CV stage only. After I set Balance to Start at Storage all is well again with the 306B.

I normaly set Balance to Start at Storage but had changed it many months ago when I was charging mostly 3S Lipolys which in fact rarely required any balancing at all. Just goes to show that one needs to keep an eye on things.

This is very true, my 3S Lipos charge very fast and need little effort from the charger to balance the cells. The little 1S 160 mah UM batteries are a lot different. Although they need no balancing the CV stage takes much longer than the larger batteries, even when I charge them in parallel at a higher current setting.

IMO, it's better to make sure the charger completes the balancing every time by following the advice in this snip from a post by Julez:

(This will ensure perfectly balanced packs. The charger will not stop charging, before the packs are perfectly full and perfectly balanced. Good packs do not need a lot of balancing anyways, but trying to balance them before they reach the CV phase might actually cause imbalance as the internal resistance plays a role here, and so the overall charge and balance process might take longer.)

I am aware of Julez parallelcharging recomendations and fully aware that he often chareged overnight at 1/10 C or so and has excellent results.

I posted

and that I am charging at 2 to 3C and FYI this means a less than 30 min. charge and in fact most are between 15 and 20 minuteas . Using Balance trickle would extend the balancing time to the point it would make no sence to even charge at the field as most times I am there for less than 3 hours often less than 2.

Believe what you will but charging in parallel has its' disadvantages and ending up with some LiP{olys widly out of balance when charging at greater than 1C with a balancing circuite with limited power is one of them..


FWIW I Have been balancing LiPoys since before there were any commeicialy available Hobby RC balancers available unless you built your own and I have been very active in testing balancers ,chargers,balancing chargers over the past 8 years in addation to testing many brands of LiPolys and feel that I have a very good working knowledge of how to best manage LiPolys.

Over all when dealing with a varity of different quality LiPolys I have found that storage voltage is the best point to begin balancing. Yes iot is true that ythis at times causes unnecessary balancing which lengthens the total procress but so does balancing at any stage even CV if one if using preinum (real not claimed) LiPolys.

Charles is different than the default settings?

I usually parallel charge packs at 5c, granted they are almost the same size, and haven't run into an issue.

Suddenly Turnigy 5s 2200 mah is reading 3.6v on cell #4 and all others 3.85 on my 106B.I have checked the battery on a Hyperion eos checker and all is fine,then put it on my Acucell 6 and it also reads it correctly.I am apprehensive to use the I Charger on this battery because it is my thought it will overcharge this cell,has anybody had this problem.I am going to charge it up until that cell hits 4.10 and see what it reads i balance from storage.
