Hi guys,

I am a little confused about batteries. I was told to buy 2S Outrage 2500mha... what 2S mean? Is this the configuration you use for .50?

I have DS1015 on Cyclic and JR8900 on tail. I will buy a AR7100R. If I understand... I will have a 6V configuration?

If you also have some advices on charger, the one you recomand... it would be great! I will need to same money on the charger for begining.

Thank you in advance!

You will hear a lot of different opinions on battery setup you can use a 4.8-7.4 just depends on what you have the money for. I use Fromeco batterys a regs and i like them but you can use all kinds of batterys and regs and some no reg. I'm not sure of what volt the servo you have can handle? I have a friend using a 4 cell 2700 mah NMHI and he or we get a lot of flights on it and i think there pretty cheap. There are all kind of chargers out there also you will have to decide on what bat you are going to run before you can buy a charger.

2S = number of LIPO cells.
so this is a 2 cell 2500 Lipo.. and it would be perfect for a Vibe 50.
I run flightpower 2S 2500s and get 5 flights on the Vibe with all digitals.

On my Trex 600N that same battery gives me 7-8 flights with analog servos.

2S -- refers to the configuration of a Lithium Polymer battery pack (usually).

These packs are made up of individual cells, each having a nominal 3.7 volt terminal voltage.

Cells can be wired in Parallel (+ to +, - to -). Doing so gets you the same output voltage as one cell (3.7 volts), but the capacities add. Two 3.7V, 500 mah LiPo cells wired in parallel will output 3.7 volts, but will have a total capacity of 500 X 2 or 1000 mah. Wired in parallel, these two cells would make a 1S2P battery pack.

Cells can also be wired in Series (+ output of one cell is the pack + volts out lead. That cell's - terminal is wired to a second cell's + terminal, and the - terminal of the second cell becomes the pack's negative terminal in a daisy chain fashion).

In this case, the voltage of the individual cells is additive but the capacity is not. Two 3.7V, 500 mah cells wired in series will give you a 3.7 x 2 = 7.4 volt pack, with a capacity of 500 mah. This pack would be referred to as a 2S1P, and indicates that there are two cells wired in series.

The S indicates series wired, the P indicates parallel wired.

It would appear from your question that you have some kind of voltage regulator for you Vibe, the person was telling you that you need a LiPo pack wired as 2 cells in series (2S) which will output 7.4 volts nominal.

The 2500 mah stuff tells you that the battery is rated to deliver a total of 2500 ma for one hour (or 5000 ma for 1/2 an hour, or 1250 ma for 2 hours or ...) before it is considered fully discharged.

The AR7100R has built-in voltage regulation, will accept the 7.4 volt input, and you will have a choice to hook your servos up to an output whose voltage is regulated down to a "safe" value for most servos, and an unregulated output which can fry servos not rated for more than 6 volts.

The AR7100R has these servo output options:

Internal 5.2V 2A regulator for throttle, gear, rudder, and aux 2 (for Gyro) channels.

AND

Dual outputs on the throttle and gear channels (regulated to 5.2V and unregulated).

Your cyclic servos MUST be rated for operation with an unregulated 7.4 volt power source (your battery). A 2S wired LiPo can be as much as 8.4 volts fully charged, is 7.4 volts nominal, and 6 volts when fully discharged. If your cyclic servos can't handle up to 8+ volts, expect smoke and fire.

With the AR7100R and a 2S LiPo, you will NOT have a 6 volt system, you will have the regulated 5.2 volts available, and you will have the raw battery voltage available. Be careful what you plug in, where.

There are all sorts of chargers that will charge a 2S LiPo pack...Triton, Triton Jr, Trion II, Hobbico Accucycle Elite, Hyperion...the list goes on and on. Buy a charger that is LiPo capable and learn how to use it, otherwise you'll smoke more than just a battery pack.

Now that guy knows batterys, i did not know all that myself. Thanks for the info on what the S and P means.

Thanks

Wow! Thank you!

I have Ace DS1015 cyclic servos, I will look if they can handle 7.4V.

Thank you again for such explanation!

If you hook a 2s1p lipo up to an AR7100R, you will have an 8 volt set up with 5.2 v going to the tail. Unless you put a regulator between the battery and the Rx.

If you mean to power your transmitter, the answer is yes, and no.

Many people are doing so, using 3S LiPos in their transmitters with no problems.

JR and Spektrum say no, you'll void their warranty and perhaps smoke the transmitter RF section.

There are two reasons people put LiPos in the transmitters:

1. LiPos have a very slow self-discharge rate. You can charge them, let them sit for a long time, they will retain most of their charge. This allows many to just grab the TX and go flying without having to charge in advance (well, as long as they know just how much juice is really left in the pack after that "last" flying session). The stock battery is a 1500 mah NiMh pack, and the cells used to make up the stock pack seem to exhibit a fairly fast self-discharge rate. If the TX sits for a week or two between charges, the voltage drops pretty quickly.

2. The stock TX battery is only a 1500 mah pack. People are sticking LiPos of 1800 to 2100 or more mah in place of the stock pack. The extra mah rating translates to longer periods between charges. But again, you need to keep track of your overall usage so you really do know WHEN it's time to recharge.

The down side of LiPos in your TX pack?

1. You probably shouldn't charge the pack while it's in the TX. If, as LiPos have been known to do, it goes up in flames, so does your TX and whatever it is sitting on or in when it does.

2. As JR/Spektrum note, your warranty is void, and there is the outside chance you'll smoke your RF output section.

-----

In the end, it's your radio, your stuff, your gamble. Roll the dice and see where they land. But then, that particular pack just might not FIT inside the battery area of the TX....

Always interesting to see your answer!

Stock battery? DX7 comes with a battery? I didn't know it!

IMO, the best pack for the Tx is a pack made of Sanyo 2700 mAH NiMH cells. Very low self-discharge (mine has gone 3 + months with holding a charge). No issues with voltage or charging in the Tx. Doesn't void the warranty. Longer life (high mAH than Lipo packs). Also no issues with pack damage due to leaving fully charged.

Only area that lipos are better than these packs is weight.

My pack came from a company called TPE. But Cheap Battery Packs will make a pack of these cells.

Better yet would be Eneloop NiMH cells. Same capacity, but should be far lower discharge than your 2700's . . . . they are designed to rival lithium cells in power retention, without the liabilities . . . .

Considering mine have held up for at least 3 months wihtout being charged, any better performance will be a bit of overkill.

You can find cells that are the equivalent of the Eneloops at your local Wal Mart. Kodak sells "precharged" NiMh AA cells, about 2100 mah each, a pack of 4 costs about $10.

Duracell is also now selling these same kind of cells.

Make sure you find the cells labeled "precharged", not just "rechargeable". There IS a difference. The ones labeled "rechargeable" are the garden variety cells that self-discharge at a fairly high rate.

With some ingenuity and skill, solder them up into a TX pack. These NiMh cells can be sold as "precharged" because they have the very low self-discharge rate like the Eneloops. After a year of sitting on the shelf, they will retain 85% of their charge.

Note -- they are sold about half-charged (not fully) due to postal regulations and shipping concerns.
