PowerExpander vs PowerSystem
Ok Im starting the planning phase of my new build. 30% Edge
I am going to be running 2 - A123's for power. My question is simple: Whats the difference between the Power Expander Plus and the Power System Plus? Other than one says NiMh/NiCd & A123 the other says Lipo or Lion...whats the diff? I have read each like 5 times and just cant wrap my head around the difference. Also, can I use the pin flag with both models? Correct me if I'm wrong but I dont see why one couldnt use A123's with the Power System instead of Lithium batteries. I really wish they made either of these 2 models with Deans in I dont need anything bigger except maybe the EQ6 which is going to be overkill for my setup. Thanks in advance. |

Seriously, this is a help forum. If you don't want to help with the products then please do not contribute. Thanks.

Airboss, things get too messy inside trying to run str8 IMO. I like the SF products, everything is in one nice neat package.
My current 50cc is with Sahara Reg and 42% products ig reg, and kill switch. Just looking for a cleaner neater install. Plus the regulated voltage vs str8 with A123's negligible...thus making it mostly for cosmetic looks |

Do NOT use the A123 with the PowerSystems units. You cannot regulate the A123/NiCd/NiMH packs to 5.5 to 6.5V. When drawing high current from a 2 cell (6.6V) A123 pack, the voltage can drop below 6V and the regulator that is set for 6 to 6.5V will shut off. I'm sure the same problem can occur with the NiCd/NiMH packs, as well. If you want to use LiXX cells with the PowerExpander, you will have to use a regulator between the batteries and the PowerExpander unit. Or use HV servos. |

Hi,
If you use good A123 or LiFe packs you can run them with PowerSystems as long as you keep the voltage for the servos at 6V or less. A good A123 or LiFe pack with Deans connectors will not drop below 6.5V. This is adequate to keep the regulator in regulation at 6V. Quote:

Ritchey, any chance you will be making or could custom make a Power Expander Sport Plus with deans battery inputs?
Sleepy, is there a thread on that, they have been in the plane now for well over 150 flights with no problems, and using Ignition reg, batt share, and cutoff |

If I use a reg, I like to have at least a 1V buffer between pack and reg voltage level . |

Hi,
If you want something with Deans then you can use the PowerExpander Competition 12. Quote:
