5 5955s and 1 5645, how much battery do I need?

[3ddd]

two fromeco 2600's into one wolverine switch into two regs set at 6.1 volts and out of the regs with four plugs to the receiver.ain't gona fail ya

But seriously though, forgo the mountain of equipment listed above with yesteryear technology. Get something up to date and less equipment.

Of course, everyone has something they are comfortable with.

My opinion, my WH SUkhoi...

I have a DX7 system for control into an AR9000 rx.
I have 5-5955's and 2 smaller servos for the ignition and choke.
I have 2 TBM 2400s into to fromeco wolverine switch into 2 fromeco adjustable regulators.
I have 1 TBM 2400 into a fromeco badger into a smartfly ignition regulator. Extremely solid set-up. Fly all weekend with no problems. Overkill? Probably. I have lost too many planes to weak battery set-ups. Overkill is the only way for me from now on. If I can't afford to overdo it (powersystem), I won't do it until I can. It's cheaper to do it once and do it "right" (my opinion) than it is to do it half-a$$ and have to buy twice.

Hey Joe--just wire the pack with 2 output leads, then run tose into 2 switches.

Thanks for all of the suggestions. I am most likely to go the 123 route. It seems simple and safe which is what I like.

Thanks!

Just ordered a setup from Sin City Jets. Looking forward to trying it out.

Easy, run 2 fromeco batts, 2 seperate badger slider switches, of course you will have to regulate going this way so 2 fromeco regulators too........ but thats the way I've done it and no problems yet, going on almost 2 years now.... Later

TYPICAL BATTERY SETUPS

You should get a minimum of six 15 minute flights using the following set ups. The ignition battery is the first to run down. If you want to fly more, exchange the 2-cell packs for 4-cell packs, or make provisions to charge the battery between flights or to easily exchange the batteries at the field.
With large, expensive airplanes, it's best to use two receiver batteries with two switches with two regulators (if regulators are necessary). These are vital components which can fail and if one does fail, bad things will happen. Having a redundant system can save you thousands of dollars and hundreds of hours of building time.
25% AIRPLANE BATTERY SETUP- 6 servo setup without smoke (1 servos per aileron, 1 per elevator, 1 per rudder)
LI-ION, LI-POLY
1 - 2-cell (about 2400 mah) Battery for ignition (gas engines only)
1 - 2-cell (about 2400 mah) Battery for Rx (2 is better for redundancy but are heavy)
2 - 6v MPI regulators **
Typically use one Rx and analog servos. If a smoke pump is used, a separate battery is best.
LI-PHOSPHATE
1 - 2-cell (about 1100 mah) Battery for ignition (gas engines only)
2 - 2-cell (about 1100 mah) Battery for Rx
Typically use one Rx and analog servos. If a smoke pump is used, a separate battery is best.
30% AIRPLANE BATTERY SETUP- 6 servo setup without smoke (1 servo per aileron, 1 per elevator, 1 per rudder)
LI-ION, LI-POLY
1 - 2-cell (about 2400 mah) Battery for ignition (gas engines only)
2 - 2-cell (about 2400 mah) Batteries for Rx
2 - 6v MPI regulators **
Typically use one Rx and analog servos. If a smoke pump is used, a separate battery is best.
LI-PHOSPHATE
1 - 2-cell (about 2400 mah) Battery for ignition (gas engines only)
2 - 2-cell (about 1100 mah) Battery for Rx
Typically use one Rx and analog servos. If a smoke pump is used, a separate battery is best.

33-35% AIRPLANE BATTERY SETUP - 7-9 servo setup with smoke (1-2 servos per aileron, 1 per elevator, 2 per rudder)
LI-ION, LI-POLY
1 - 2-cell (about 2400 mah) Battery for ignition****
2 - 2-cell (about 2400 mah) Batteries for Receivers
3 - 6v MPI regulators**
Typically use one Rx and digital servos. If a smoke pump is used, the Rx battery can be used, no separate battery is required.
LI-PHOSPHATE
1 - 2-cell (about 2400 mah) Battery for ignition (gas engines only)
2 - 2-cell (about 2400 mah) Batteries for Rx
Typically use one Rx and analog servos. If a smoke pump is used, a separate battery is best.
36-40% AIRPLANE BATTERY SETUP - 9 servo setup with smoke (2 servos per aileron, 1 per elevator, 2 per rudder*)
LI-ION, LI-POLY
1 - 2-cell (about 2400 mah) Battery for ignition****
2 - 4-cell (about 2400 mah) Battery for Receivers
1 - 6v regulator for ignition**
2 - Adjustable Voltage Regulators
Typically use one receivers and digital servos. If a smoke pump is used a separate battery is best***.
LI-PHOSPHATE
1 - 2-cell (about 2400 mah) Battery for ignition
2 - 2-cell (about 4800 mah) Batteries for Rx
Typically use one Rx and analog servos. If a smoke pump is used, a separate battery is best.
36-40+% AIRPLANE BATTERY SETUP - 11+ servo setup with smoke*** (2-3 servos per aileron, 1-2 per elevator, 2-4 per rudder*)
LI-ION, LI-POLY
1 - 2-cell TBM Li Ion Battery for ignition****
2 - 4-cell TBM Li Ion Battery for Receivers
1 - 2-cell TBM Li Ion Battery for Rudder
1 - 6v regulator for ignition**
2 - Adjustable Voltage Regulators
Use Y-harnesses for each pair of batteries into the switches so extra regulators are not required.
Typically use one receiver and digital servos.
If a smoke pump is used, the Rx battery can be used, no separate battery is required.
LI-PHOSPHATE
1 - 2-cell (about 2400 mah) Battery for ignition (gas engines only)
2 - 2-cell (about 4800 mah) Batteries for Rx
Typically use one Rx and analog servos. If a smoke pump is used, a separate battery is best.
*Rudder set ups for 40%+ planes is usually two Jumbo servos or three or four high powered small digitals. However, a single Seiko servo can be used which has twice the power of these set ups. The Seiko battery requires its own power source which can be a separate battery or the ignition or receiver battery can be used. When using 4 digitals, it is very difficult to match them up perfectly, consequently there is more power loss and faster battery drain.
** Regulator option: Use MPI Miracle switch with built in 6v regulators ($40) instead of MPI 6v regulator ($20)
*** Smoke system option: Sullivan makes the best smoke pump now. It's best to run this pump off of a 12v battery. The best option is to power the smoke pump with a 3-cell Li Ion pack at 12v. Charge using your 3+1 charger's transmitter charging port to charge this battery.
**** Ignition option: Generally the ignition battery is the first to run down if you are using a 2-cell battery pack. Using a 4 cell pack is an option.
*****Making parallel packs: You may have heard the term 2s2p or 3s4p and so on. The s stands for series and the p stands for parallel. Li Ion packs can be run in parallel without a problem like NiCads. While one bad NiCad cell can ruin an entire pack, one bad LiIon cell will not. If you want to join packs together in parallel you simply solder them together or use a Y-harness HOWEVER the packs must be the same capacity and must be in a similar charge state. You don't want to join a run down set of batteries with a fresh set otherwise they will always be mismatched. Just charge both sets up fully, then join them together.
