What is price for turbo booster?
Are they seperate units for differing voltage ?or
does one unit do all voltage ranges?

If not what is the range and price for each unit? thanks

To answer your question. The turbo box is a single module that works with all of our batteries. The module is sold with our batteries in the Hypersonic kits, go to www.a123racing.com for purchasing information. It is not currently sold individually mainly because it is not recommended for use with other batteries. The turbo module draws high amounts of current which our batteries are capable of delivering. Use with other packs may damage the Turbo module and/or your other battery.

Please let me know if you have any other questions.

Brian

Status: offline 		Ok, Thanks, what is the voltage range (input and output) for each unit?
I think if I understand correctly it is the same module for the 7.2-10.8 and if I got that particular unit it would also work for 3S batts and go up to 14.4?

Your batteries seem to operate at a slightly lower voltage than conventional Lithium Poly batties? I assume that the mandatory cut-off voltage is also lower. What is it? If I am configuring a system for aircraft operation that would normally be 6S, do I need to add a cell to work with your system?

You have the voltages figured out. The 2S packs can output 7.2V-10.8V when the turbo module is used. The 3S pack can output 10.8-14.4 when the boost module is used. It is the same boost module, when you plug in the battery it auto senses what type it is, all you have to do is choose the voltage setting.

Bob, I answered your question in the battery thread.

Brian

Status: offline 		How is the cut-off handled? My concern is that if the Turbo module cuts off there will be no power to the ESC, which means no power to the receiver, which means crash. Even if I program a cut-off in the ESC it wouldn't cut in as long as the Turbo module is maintaining the programmed voltage. This seems problematic.

Status: offline 		The turbo is a voltage booster, not a voltage cut-off. The voltage Brian is talking about is output voltage I think and is the same or higher than input voltage.

A related question, if 12 volts were supplied would the output still be 14.4 max? thanks.

Status: offline 		If the Turbo Booster doesn't have a voltage cut-off it will seriously damage the batteries when the battery drops below the threshold and the output is still maintained. You would need some other device in between the battery and Turbo to monitor it.

Status: offline 		These cells are supposed to be able to take that ok. They also fall off voltage very fast and with the booster it will make this condition even worse (better). I would love to hav batts like that, just like running out of gas. I'm not sure that it is best for them to kep being discharged low, and a lcv may also be a great idea.

Status: offline 		The voltage is stepped up and therefore the current must also be stepped up. The current capacity at the higher voltage is less than it is at lower voltage, but if you are not even close to limit then it works fine.

The total power shall remain the same (less a small loss)

I Have a Multiplex Easy Star powered with a Warp 4 4 turn, Castle Creations Phoenix 25 ESC, and APC´s 6*4e Prop.
Do you recomend the Turbo System for this configuration?
2S1P or 3S1P?
Does the Turbo System Includes the Charger? Can you charge this batteries with a Hobbico Accu Elite Pro Charger / Cycler?
Do you need a balancer for this packs?
Thank you

What is the voltage and amperage tolerance of the "Turbo" module? Specifically, what would happen if I ran two of your 2300 3S packs in series, in essence (6s1p) through the module?
