Parallel charging Board for 6 packs 2~6S (T Connector) (USA Warehouse)

Well I got this from the US Warehouse with my last order . I planned on using this to charge my smaller packs for my 1/16th scale and 1/18th scale cars but I have found that this also handy for slow charging my larger packs in bulk . So far I Have no complaints especially when I could have paid a lot more for a very similar product and since I won't be using this to much I think why spend money I don't have.

For those that don't understand the benefits of using this device I will attempt to explain .
If you have a charger that has the ability to charge at a higher and rate then your batteries are recommended to be charged at you are wasting precious time . My personal example would be my GT power X-charger C6 It is rated to charge at up to 6.0 amps when charging a 2s lipo battery pack  rated at 1500mah and a 1c charge rate .  What happens is that this board connects the batteries in parallel to each other and then connects to the charger . The charger only sees the batteries as one big battery when connected like this and when the batteries are connected in parallel the charge rate is divided among them . So if I connect 4 batteries rated at 1500mah and charge them at a 1C  rate then I will be using the full potential of my battery charger .

Now as my public service announcement :

All Batteries That You Plan To Charge Must Be Of The Same Capacity at the minimum but personally I will Only be charging packs of the same rating from the same manufacturer .  

Manufacturer's description :

Charge SIX (2~6S) lipo packs with same capacity & cell count simultaneously with this parallel charging board.

That means you can charge 6 3S 2200mAh or more at the same time with a standard charger!

News flash Turnigy Stadium King 2wd truggy / ZD Racing ZMT-10 Brushed motor model is 3s capable

Well I decided just for giggles to see is a 3s lipo would burn up the esc for my ZMT-10 and was surprised to find out that the esc recognized that the pack was a 3s . Normally the esc ( currently in a Clodbuster ) Goes through its little beep sequence and I give it little thought but when I hooked up a 3s lipo to the esc I knew something was different instead of the normal BEEP-BEEPBEEP-BEEP IT WENT BEEP-BEEPBEEPBEEP-BEEP signalling that the voltage cut off recognized that the pack was a 3 cell I couldn't believe it . after driving for a bit the esc showed no heat increase so I feel safe in saying this esc is good to go on 3s lipos but I still recommend a lipo alarm as the voltage cut off is too low for my taste.

Hobby King Programming Card for Car ESC (USA Warehouse)

Well it does exactly what it is supposed to do its only downfall is that its construction is primarily a circuit board and card board and it doesn't seem like it would put up with much abuse so I recommend keeping it in a  safe place. I do wish there was a cheat sheet for the buttons as there layout makes it a little hard to remember what the far left and center arrow functions are unless you use it constantly.

According to my research this programing card works with these esc's

YKS 5000mah 20c lipo batteries my opinion

Well I bought a 5000Mah 20c 2s 7.4 v lipo battery pack from a company in Brooklyn New York .

06/10/13 - 09/01/14 RIP

Minimum Capacity:	5000mAh
Configuration:	2S1P / 7.4v / 2Cell
Constant Discharge:	20C
Peak Discharge (10sec):	30C
Pack Weight:	308g
Pack Size:	145mm x 52mm x 30mm
Balance Plug:	JST-XH
Discharge Plug:	NO
Quantity:	1

I had  good experiences with their smaller batteries as can be found in other parts of this blog but I find myself not being able to recommend this pack and many of their other higher capacity packs .

 This particular pack was the best deal as far as I could see but after getting it  I realized it wouldn't fit anything I owned its several mm wider than a shotgun style NIMH pack  and longer than a 6-cell pack but slightly shorter than a 7-cell pack . This made fitment virtually impossible in almost all my models but my ZD Racing 1/10th scale truck and really it was such a tight fit that It makes me uncomfortable . 

The other problem I had was that the power output in my opinion is low even for a 20c rating I found I could only get reasonable performance for around half the pack after the voltage dropped below 4.0 volts it could not provide the amperage needed for my mild brushless system that I was testing it with . The measured usable  capacity was normally around 3000 Mah .

This pack has a Relative Amp 20C x 5A = 100rA 

$12.99 / 100rA = 0.1299cE the lower the number the Cost Effective

Now looking at this graph it should give you a idea of why my battery didn't meet what most people would expect from the ratings  . To clarify if you don't see what this is showing is that the mah rating was determined at a 1C discharge or a 2.2 amp draw but when a 25C load  was introduced the usable capacity dropped off from 2250 ish to 2050 ish .

Its also Important to note that when a manufacturer uses this method that the gap between the  listed capacity and usable capacity gets bigger as the capacity get bigger . This is one of many reasons why most sellers and battery makers don't use the 1C discharge method to determine battery capacity.

The reason I find it hard to recommend (or even buy ) there other higher capacity and C rated batteries is that for the cost you could be buying a battery that is well known in the hobby community for good performance and value with a more appropriate battery rating  .
