Etha board voltage question

I have been looking to use some rechargeable batteries in my guns for awhile now. One thought is to use small LiPo batteries, the kind that are popular in the RC hobbies. The main problem I see is that LiPo batteries come in 7.4 volts (2 cell) and 11.1 volts (3 cell). So the question is can the Etha (or any PE board/solenoid) function off of 7.4 volts or handle 11.1 volts?

I am going to say that you probably will not get very many full cycles on 7.4v. On the other hand I would have no problem using the 11.1v cell in the Etha, if you think about it people have used rechargable 9v's forever and at full charge most acually hold about 12.6v.

Just my thought, Ex.

Does the Etha have a "high power" option like the Ego or Geo? If so, I would imagine it could handle 11.1v. I just don't know if an extra couple of volts would cause excessive wear or damage to the 'noid or circuit board if used on a constant basis.

I would recommend that you contact Jack Wood, (he is a PE Guru/Stud/whatever you want to call it),

He will have your answers. Hopefully, he will answer in here, as I would love to know the answer as well

DO NOT use an 11.1V battery in an ANY ECLIPSE GUN unless you want to buy a new board, it will damage the capacitors in the regulation circuit.

7.4V will be okay provided that the ambient temperature is not too low. Of course the battery indicator will be meaningless as it is scaled for alkaline batteries.

There is also no voltage cutoff circuitry in the board allowing the voltage to drop too low on any lipo will damage the cells. An alkaline 9v lasts forever in a marker. What's the point?

I have used (non-rechargeable) lithium batteries in my guns for a few years now without any problems. I like their flatter power curve, better performance in the cold, and lighter weight. Those bad boys will keep dishin' out a full 9V until they're pretty much dead.

solenoid is working with 6VDc voltage.
board inputs power is 9volts.

that means something in the board reduce voltage to power the solenoid.

to check if all the board is able to work longtime @11.1 volts you need to follow power inputs and check datasheets of all components on the board.

Like a RESISTOR? I dont have a board in front of me.... But I do have a solution. I know the APE boards can handle higher voltages, why not use those LiPo Batteries, with the APE board?

I wonder if the same is true for the Virtue boards.

There is a big difference between lithium ion and lithium polymer. He was specifically asking about lithium polymer rechargeable batteries.

Right on, man. I was just sharing my positive experience with the non-rechargeable lithiums.

Thanks for all the responses, and 7lash for the definitive answer I was looking for. LiPos are super cheap and I have a charger already. I could buy a few lipos that fit for around $5 each and have a superior battery. Only hang up is the voltage. It is probably more feasible to buy a few standard rechargeable 9-volts than to buy a new board just for the capability of running a higher voltage battery (for now at least).
