Default Recomend a charger for me

OK all, I'm back into electric (again) and I need a li-po/A123 cell charger/ balancer. I need one that will do at least 4S li-po's. I don't want to spend 200 bucks on it. I would prefer to keep the price near or below 150. The Extrema looks good but a little pricy. Does anyone have experiance with the FMA? I'm really just looking for your experiances so I don't buy junk.
Thanks

Ya, I looked at it but it does not balance and will not charge A123's. It looks like a nice unit though.

I just bought the Balancepro HD from FMA. I should be getting it some time next week and let you know how it works. It charges all types of lithium cells.

few chargers will have the ability to charge A123 packs, since the form of lipo is very unique, i think your best bet is the duratrax ice, it can charge
ni-cd, ni-mh, and the generic type of li-po (Orion carbon and platinum li-po for example).

I dont know what to tell you for charging the A123 packs, but for anything else the duratrax ice should be on your pit table.

Ok. I bought that charger and the universal pigtail. Total came to $125 for everything. I am going to end up making adapters for all my packs. I am going to make them all like the Team Orion lipo pack, just balance port type. I have a maxamps 4400mah saddle pack that I took apart already, an rc common sense 4000mah battery, and going to be getting some A123s soon.

If your buying a charger for electric RACING and looking at the ICE, take a look at the Checkpoint. Same programming but better features for NiCd, NiMh, and bruhed motor. If you aren't worried about that, save the few bucks and get the Ice.

They are the same charger except the Checkpoint has some updated stuff.

It does not do A123 cells, but for a great lipo balancing charger, check out the Digital Balance Charge from Common Sense RC. It is very nice for balancing and displays each cells voltage individually so you always now how well your cells are balanced at each charge.

Any charger that allows you to specify your exact charge voltage and current for lipo while performing a CVCC charge, will charge the a123 cells. You need to change from 4.2 volts per cell to 3.6 volts per cell charge rate. I think the MRC 959 allows this, and you can always wire up and external balancer to a charger without balancing capabilities for about 30 bucks. My brother uses the electrifly external balancer with his 959.

But that is the main difference to bear in mind, the a123 uses CVCC (constant voltage, constant current) like all the other lipo's, it just expects a charge voltage of 3.6 per cell as opposed to 4.2 like most other li-xx batts.

Well, I received the balancepro hd 6s charger yesterday and at first glance without using it, visually I am not impressed. It looks like as if it was assembled in someones garage. The charger case appears to have it's screw holes drilled with something like a drill press because there are imperfections.. The case itself appears to be machined though. I have a small area on the display area that appears to have some sanded off paint too which kind of sucks. Also, the knob that controls current feels very soft and squishy. If I gently push it doesn't seem as if it isn't mounted to anything inside. It feels like it is just soldered on the board and that is it. It should have screws inside and mounted to something so it feels more 'solid'. Also, the sticker which tells me that it is set to A123 mode seems to have been put on by a blind person, so I removed the sticker and placed it on 'better'.

So it is not at all aesthetically pleasing, but all that matters little if it can charge lipos and A123s well.

I still need to solder up some connectors so I can charge my rc common sense 4000mah and maxamps 4400mah lipo saddle pack batteries. Hopefully today when I get off work I'll have time to do all this.

What I am going to do is use the FMA universal pigtail, solder on male deans to red and black wire, and use align male bullet plugs for the balance wires. Then all I have to do with all my packs is solder on female align bullet plugs to the node connectors and I can charge all my packs with it, no proprietary connectors required anymore!
