Hey guys,

Will this power supply work to power my Pro-peak Prodigy 2 lipo charger? I will be charging Apex 2100mAh 3s 15c packs.

I think it will work to charge your apex batteries but that charger can put out more amps then the power supply is capable in other situations for different batteries, I would invest in a higher output power supply, like at least 10 or more amps, so you can run a few different chargers at the same time, example I run a poly4 charger and sirus charger at the same time on my power supply to charge my lipo's and tx, rec, packs at once.

I am using the Pro-peak Prodigy to charge my TP 2100's. Like Coolpowered said, invest in one with more amps. Spend the extra money and go with the 15 amp version

$42 for 3 Amp.


pfffffffffffffff

get a 15-25Amp supply

$42 for a 3A supply is a total rip.

If I'm only charging at 2.1 Amps, why do I need a 15 Amp power supply?

Hi All,

Keep an eye on ebay. I picked up a nice 12vdc 13A supply for 20.00.

Cheers,

The Pro Peak 20amp ones that RCHover sells work awesome and they are in the 60-70 buck range.

...Once upon a time there were Nitros, flybars and frequency pins...

I started using an old power adapter that was used with a portable DVD that outputs 4 amps... it powers my charger fine, but does gethot by the end of the cycle... I think that Radioshack one might be a little small....

But Honey, I can't live with just stock.....

Could I just get a little lawn tractor battery at Wal-Mart or something and use that? It's small enough and it's sealed to use indoors. Then I can just recharge it when it gets low and it's ready to charge again!

You could use a battery to power the charger but under load the battery terminal voltage could drop a bit which could cause the charger to diaplay the 'input battery voltage error' alert and then hault the charging process.
You'd be better to get a bench PSU, I've been using a 3-5A supply for years now and not had any problems.

True, but for the price you would be better off to by something better now than pay for it later. Your looking at $41.99 for the 3Amp and $71.99 for the 15Amp. A cost difference of $30...

I am charging a 3s2100 TP pack which requires 23 watts not including losses.
The 15A power supply puts out 200 watts. More than enough... So you could get by with the 3Amp.

The way I looked at it was in the long run I might have 10 batteries, who knows... So say I don't want to wait and charge a single battery at a time and I buy another charger or two. Now I have the ability to charge 3 batteries at once and I don't have to buy another power supply because the one I initially bought was capable of this.

So you could do it, but for the price why not pay a little more and look at the future. If you buy the 3Amp and eventually need more Amps to charge more batteries or a larger battery than you currently have you would have to buy another PS. From my experience when you buy something cheaper early you'll end up paying double for it in the long run.

I converted an old PC power supply to provide 12VDC. It outputs up to 8 amps at 12V. It cost $5 at a computer swap meet, with another $10 worth of parts, a few hours of time and works fine for charging my lipo's. I also use it as a 3V and 5V source as well, for breaking-in small brushed motors and as an rx power source.

YOu best bet is to buy a power supply off ebay. I got mine for 40 bucks shipped and its a 13amp, 12V power supply. It also has two outputs so you can run two chargers if you wanted as long as the combined current is 13amps.

Here is a really cheap on onebay right now:

Problem solved!!!! I remembered that I had won a battery jumpstarter/air compressor/power supply at work as a door prize. I took out the battery and voila! Instant power source for my charger. It is a sealed and maintenance-free lead-acid battery. It has a 19Ah rating. Putting about 1600-1700 mAh into each lipo, this thing will charge many of them before it needs recharging itself. I can just recharge it with my standard car/boat battery charger when it gets low. The included AC charger lists 12v, 700 mAh charge rate. My charger will do 2, 6, and 10 amps. Could I set it for 2 Amps and be ok or do I need to cut off the end of the included charger and use that? Zero cost! Woo hoo!!!

Now, a related question...What is the proper break-in period for lipo's?? Should I charge and discharge it on the charger a couple of times first? If so, what are the recommended discharge settings? I am charging at 2.1A.

blackkat98,
Charging is good, discharging with a load or charger is just throwing away flight time. Charge the Lipos. Fly gently for 5 or 6 minutes and land. Repeat this procedure for a least 6 flights to break in the Lipos. I have used this procedure for over a year now and am still flying some very old Gen2 TP2100 Lipos. They refuse to give up so I keep using them.
I use the Power Supply haz recommended. I got it from modefos.

Hey if you have an computer power supply laying around you can always use that it is not hard plus if for some reason you need dual voltage (military people in general) this is a great way to go.
