Is a second battery a good investiment for this? How long will the run time be with two batteries?

yes a second battery will help, also you can get higher mah battery. i run a 2000 mah battery and fasten under the helicopter for a longer flight time off one battery, I did leave the battery that it came with inside and the second underneath the copter and of coarse change the connections on the batteries so that all i have to do is unhook one and hook the other up and i'm flying again.

It runs about 6-8 minutes on a charge. So yes a second battery will help. But you still get about the same run time. 12-16 minutes.

If fully charged and used at 2 LPM the battery should last 4 hours in your ever go. Two batteries would be a total of 8 hours use.

It should last about 3 - 4 hours in low, but in the higher speed it will only last about 1.5 - 2 hours. We just make sure we charge it after every use and haven't seen a need for a second battery.

I would advise against running it in a two batteries to one panel setup. If one battery went bad it could/will cause the loss of the other battery. The charging controller in this unit is meant to work in a one to one relationship to a single battery. Properly wired it could possibly work as a temporary solution. Is it advised? No. Eventually there will be a massive failure when one battery in the circuit has problems and an overcharge hits the remaining good battery. I would suggest a Battery Tender 022-0165-DL-WH. This is a dual battery charger but is not solar powered.

The vacuum runs right around 7 minutes for us. Worst case you could buy a 2nd battery. The suction is very good on hard surfaces and OK on short carpet. We love the vacuum overall.Bill

The batteries only have enough stored power to run a headlamp for about that length of time. You can get extra batteries for very little money on Amazon. Keep them charged and with you and the inconvenience will be minimal.

I used one and it lasted 4 months. The second battery I had, which was purchased at same time, was inserted in collar and has worked fine for two months so far. Maybe you just got an older battery with not as much life.

I have only one battery, but you do not two unless You are using a lot--this battery will last for a long and is quite fast to be get it off the batter. I don't use what you use, so you may two batteries.

i alternate between two batteries. Assuming your lens cap is off when you take a photo, so I dont think you have anything to lose to get another battery. Just my opinion, of course.

Yes it will work as a 2nd battery because the two batteries work independently - only one at a time. Just make sure you use the correct chargers on the two batteries - they will have different chargers now.

I think I'll get two.These are only supposed to be good for roughly 300 cycles. That's not even a year of use if used 1x day.And, the batteries have been known to fail prematurely.

It seems to have a very good battery life, however I'm considering a second battery keeping the second charged if I neglect to charge it.

I'm sorry, I did not keep track of how long it took to charge; I just did them overnight. Once it's charged, according to the camera readout, it is good for more than 6 hours of running. The two batteries should be good for most conceivable situations. I have pretty much stopped using the charger that comes with the camera.

Yes, adding a second battery using this switch is simple. Kevin was replacing an old battery and adding a second so everything he described is correct.

Double a and rechargeable batteries work well in it. You don't wanna go cheap on the batteries because they will drain faster.

I have it maintaining 2 batteries in parallel at the moment and it works great for maintiance. As for conditioning I suspect it is better to do 1 at a time.

A hour or two. Very worthwhile. The price is cheap enough to have sufficient power to do the job. Don't plan on a quick recharge. Just have enough for the job. If the job is very long. You can recharge while the other batteries are working.
