Nice lipo but poor connector
933216
Good quality lipo battery, although Venom's Traxxas style connector was so hard to connect and disconnect that I had to solder on a real Traxxas Connector and now it is much easier to connect and disconnect. Takes a charge well and both cells balance out nicely. Arrived with each cell at 3.8 volts. Has a lot more power and provides a longer run time than the 8.4v nimh pack that I was using. Would have been 5 stars if the connector had worked as designed.

Ok so I bought the lipo 5000mah it came in really fast but i charged it with a traxxas charger (not a balance charger) and it got puffed up and cracked the hard case it runs fast but I don't know if the puffiness will go down or stay

The supplied male and female trailer connectors are poor quality.
The screw terminals are sharp on the bottom and tend to cut the wire instead of securing them!
I solved the problem by soldering the wires directly to the terminals after discarding the screws.
Also I had to adjust the tension on the brake light pin to get a good connection.
The module itself works great and mounted behind the left side plastic cover on my 2011 FLHX.

What I love most about this multi battery charger are the connectors.  I've tried several different ones and all the connectors always slip apart.  I tried them with some other batteries I have and the connection is the same as with the batteries it came with...firm.  The one critic I would give are about the red and black cables the connectors attach to.  For the price being charged some heat shrink tubing would give this product a more aesthetic look vs. a jumble of cables.  Although I like to use 700mah batteries for prolonged flight, these work great and charge great.  I did receive this set free for testing/review, but regardless I would pay for it.  I appreciate the seller giving me this opportunity and sorry for taking so long to post my review.

EDIT 26 Mar 16:  Unfortunately after a few uses the charger overheated while plugged into the same laptop USB port I've always used..  Within 1-2 minutes I started smelling melting plastic and when I touched it it burnt me and the plastic was very soft.  I immediately unplugged it before it caught on fire.  That's my finger print on the melted plastic you see.  Be very careful when considering buying this product.

The battery was the correct size physically and power. It charged properly but when I was ready to connect it to the model it had a larger connector and it wouldn't work.  I replaced the connector on the model and then it worked. I consider this situation my fault for ordering the incorrect unit.

Not bad. Some of the connectors didn't fit, so had to make that work.

Over all it's a really nice PDB. I suspect that some of the hardware on the board is operating at a minimum voltage. With a 3S lipo there is a noticeable buzzing coming from the board. I have two of them so I made sure it was common to both boards. Ran it for 12 hours on a power supply and no issues. I put a 4S lipo and the noise is completely gone. It's not a problem persay but just an observation. Beginners need to remember when making the solder bridges that "vcc" means direct voltage. If you make a bridge on the cam or vtx on vcc then you will have your battery voltage direct to the cam or vtx. This normally isn't a problem on the vtx but most cameras can't handle that.

No fault of of the device but I found it hard to keep the battery /  battery charging connector protected. I tied it up into the handlebars with itself but it eventually became damaged and the battery tried to ignite the battery case it came with.

One of the wire soldered onto the connector was cut, I had to solder to make it work. It functions very well after the fix.

On the second use one of the xt60 connectors pulled off of the board.

Edit: The vendor offered a replacement unit unprompted after my review.  The solder joints look much better on the new one.

The batteries work fine for my Syma x5c-1. However the charger is horrid. It charges batteries to 4.4 volts, well over the maximum voltage of 4.2v a LiPoly should ever be charged. Also, the solder on the MicroUSB port broke and I had to resolder it to make it work again.

My 8 amp charge controller failed after (2) days of operation.  I am an electronic tech and during my troubleshooting I observed that  some of the supplied cables were not built correctly.  The male pin is not positive for all the cables.  I'm waiting to hear from Nature Power.  But please check your cables before you energize.  Correct polarity is critical for battery operation.

I bought this male-to-male Cigarette Lighter Adapter (CLA) cable for use with a Powerfilm F15-1200 folding solar panel/RA-9 Charge Controller setup and a small 12 volt lead acid Gel Cell battery during a 3 week missions trip to Haiti in June 2011.  The cable worked to allow the connection between the panel's/charge controller's female CLA to the battery which I fitted with a female CLA.  The problem I had was that the cable ends only have a single friction spring tension clip (or whatever that thing is called) to keep the plug in the socket.  On the side with the Powerfilm panel/charge controller socket, it worked fine presumably because the socket was a tiny bit smaller than the the splitter I used or the female sockets I fit to the batteries.  Perhaps these sockets are slightly too big, but the end of the cable that I stuck into the socket on the battery end would just pop right back out. It is pretty frustrating to set up your solar panel to charge a battery and leave; then come back hours later to discover that the end wasn't making contact and no charging happened all day.

To get around this problem, I add a couple small pieces of electrical tape stacked up on the side of the plug opposite the single spring tension clip.  This gave enough extra friction to the clip and just made the plug "sticky enough" to keep it plugged in.  With repeated insertion each day, before long the little tape stack would start to slide off and I'd have adjust or re-tape it.

If this cable had double tension clips like better quality CLA plugs have, this would probably not have been a problem.  I could have not used this cable and just bought the male CLA adapter cable from Powerfilm ($), but it is easier to not have to undo their "marine grade" connectors to switch ends whenever I want to attach a little AA battery charger to the panel or just switch things around.  This cable would be perfect if it would keep itself connected in the socket I stick it in without needing to rig it with tape.

The charger is pretty chintzy. The batteries fit fine and work well in my Syma X5c. I rated this a 4 star because the connector is not quite the same as the Syma 5c connector. The connector does not "fit" all the way into the receiving connector like the original Syma battery. This leaves a "loose" connector that absolutely causes occasional loss of power or difficulty keeping power applied when shutting the battery door.

If FIXED this problem by shaving off the "TINY" bump outs on the side of the connector above the wings. These are difficult to see, but they
do impede a complete insertion of the connector, Once removed, they plug in just as well as the original battery.

Hope this helps.

Battery seems great. The connecters are "so so" on my short course truck tekin rx8 speed control generates a little to much heat for these connectors and they slightly melt and can lose connection.. The battery itself is good, just put a decent connecter on it.

I had the same issue as another customer .... the connector doesn't fit my phones but the batteries (I needed 5 of them) work very well. So I used a soldering gun to switch the cables from the old batteries to the contacts on the new batteries (rather than perform micro-connector surgery on the connector). Not a big deal. Good price. Shipping took longer than I expected but I am happy if all 5 batteries give the life back to my phones what I need. Thanks.

This product has been good so far but I'm anticipating a failure soon on the account that it's not rated for a 2s lipo my fault not the servo. However has done fine so far been about 5 tanks of gas. I don't take it easy by the way and race on the weekends.
