Venom-RC states that the battery should be cycled 12 to break it in or for it to reach maximum potential. What voltage should it be discharged to?

The charge, discharge rates and minimum discharge voltage rating should be printed on the battery. From what I understand you should never discharge a LIPO below 3 volts per cell. So for a 2S battery it would be no lower than 6 volts over all.

The 3000mah, 7 cell NiMH battery that comes with the Bandit will get better once it has been cycled a few times. NiMH batteries "wake up" after being cycled. This will result in more power and longer run times. Be sure to charge it completely...until it's juuuust warm. A peak charger such as the Traxxas EZ-Peak will take the guess work out of battery charging. I think run times should be more than 7 minutes, more like at least 12-15 minutes from my experience. Hope this helps!

I had the same problem. So, I tested the battery with a multi meter and it tested at 4 volts dc. That was the condition it arrived to me in. I tossed it in the trash and bought an equivalent from RADIO SHACK. It tested at 12.3 dc volts. I hope this helps.

It charge for 12V Lead-acid batteries.Maximum charge voltage about 14.8V.Maximum charge current is 25A.( Charge current is limited by the voltage(14.8V) and 25A.)

It's a 9 volt battery so when it's fully charged the voltage should be 9 volts.

For lithium batteries, the voltage quoted is the minimum voltage. So this battery has a minimum voltage of 11.1V, maximum 12.4V.

Usually a battery will shed excess charge as heat as it comes to capacity. I would check the voltage of the cells with your digital volt meter. If you do not have one get one immediately. It can save you from exploding batteries, a smoking crater where your home was; or injury.

1. You should use a charge controller to reduce risk of damage to the battery. 2. probably 3.3 amps but no way to be sure without seeing the label or cell spec

A 12 volt 7 amp battery works best ! If you try to use a larger size, it probably will not fit inside the control panel and not charge as fast or all the way.

lets say your battery is at 11v and a high sunlight charge from the panel pushes in 13~14v, the read on the battery will show a "soft" 12v. the shade comes in and the battery goes back to 11v. Next time you see it, be amazed to see how many amps your controller cranked up.

Several possibilities for the problem. Use quality batteries such as Duricell and be sure to buy from a supplier with a high turn-over. Be very sure that the battery's are fresh. Even a dead battery will measure 1.5 volts but it will not be able to deliver the required current. When operating with low voltage, contact resistance is always a problem. To minimize this resistance issue, always spin the battery's after installation, this polishes the contacts. There is always the possibility that the unit is defective. I have not had any problems with my unit..............hope this helps.............Bill Several possibilities for the problem.

The C rating is the rate of Amps at which the battery can discharge in a continuous burst. To do the math to get 1C which is for charging (don't charge higher than 1C) you take the mAh and divide by 1,000. In this case, 10,000 mAh (milliamperes per hour) divided by 1,000 will have a charge rate at 10 Amps. To see the safe discharge rate you multiply the 10 Amps by 35C and it can discharge at a rate of 350 Amps safely without damaging the battery. BTW this battery is like having two 5,000mAh batteries stacked on top of each other. It's a large battery.

I have had a Bull Dog ready to bark and bite intruders for more than five years and have never had it adversely affect my 12V battery. Test your battery and check the date you bought the battery.Dean

My charger, a ThruNite MCCC-4, outputs a charging level of 4.2v. When the battery reaches this level, shown on LCD panel, it shuts off, fully charged. The battery "likes" to hold an operating voltage of 3.5, so using a charging voltage of 3.8 would be conservative, and certainly safe. These batteries are very robust, and will not take more than they're designed for.

Your choice. All you are doing is breaking the circuit. Generally it is breaking the positive side (hence the red color of the switch). Worked great on my battery bank to cut off charging when not needed or based on battery temps.

You need have a proper Lithium ion/polymer (same thing!) charger. They will measure the voltage, and if it is below 3V, it will charge at a very low rate until the voltage is higher than 3.00V, when the standard 1C charging rate will kick in. (for this battery, 1C * 0.38AH = 0.38A) Sometimes you can go above this charging rate if the battery can handle it. After The battery begins to peak at around 4.00V, a constant voltage of 4.2V is applied and the current falls to 0.1C. After reaching 4.20V, the charger then turns off and lets the battery 'rest'. Once the voltage begins to fall, it kicks back in again. You need have a proper Lithium ion/polymer (same thing!) charger.

This battery '***almost' fits into the battery compartment to replace 8 AA batteries where those 8 AA's deliver a nominal 12 v for a transmitter. The advantage is a single battery to recharge, and some transmitters won't even operate with 8 recharageables which have a lower voltage. *** I had to carve away an eighth inch from the inside of the battery compartment to squeeze the Venom into place. For your parrot, this battery delivers just 1.5 A (0.5c) continuous and I don't know the Parrot, but my RC Plane uses 10 times that amp rating as a minimum. . . NO. Look at the Turnigy 2.2 (2200mah), 25-35C which is slightly longer and more square. Turnigy Nano-Tech 850, and down to 350 for lots of amps, smaller and smaller to fit (not sure how small and light you need), but the 850 and 350 don't last as long of course.
