Lipo battery for whites detectors

One more point about lipos...They are finding applications in some other devices now than just outside RC planes/cars. Indoor tiny planes and helicopters are also using them, as is I believe my electric smokeless cigarette. When I skimed over it's instructions I believe it said it used a lipo and not lithium ion. If the risk of lipo use these days was outragelous more of a risk then other battery types I doubt companies would stick their neck out and be using them in indoor craft and such. RC transmitters also use them a lot these days, something you are holding in your hand at all times during use.

All things applications are for several reasons- Small/compact/light with increased capacity over other much heavier battery types, as these are all among a lipo's major perks, ability to handle high amp draws (when needed in a device), quick 1 hour or less charge times without stressing the battery and shortening it's lifespan, and also due to the fact that these products they are being used in are protecting the soft shell that lipos use.

A tiny foam indoor plane usually has the lipo well protected inside of it, although I have owned some tiny indoor planes where the lipo was exposed just strapped to the side. A smokeless cigarette also of course has a hard outer shell to protect it (if my memory is right and mine uses a lipo). RC transmitters also of course well protect the battery.

In outdoor planes the protection is usually well inside a foam body or such, but as said I've wrecked some planes pretty hard and the battery flew out of them and still was fine, or was dented but still worked well (after close observation for a few days in a fire proof spot).

In areas of hard abuse potential from dent/cuts/dings/slamming power tools down on the ground/etc, there are other battery technologies using hard outer shells to protect them from such potential abuse that are more well suited to the risk, such as A123 cells and so on. A123 and one or two other newer battery technologies are showing up more and more in various devices due to their ability to handle even more abuse in various ways than other lithium based batteries. Some tool manufacturers even have developed their own special blend of battery chemistries to stand even harsher abuse in various ways from their products.

You can look at it this way...If you compare the risk of gasoline and keroscene, gasoline can create fumes and explode easier, while kerosene will light on fire easier in liquid form in certain ways. Neither is "safe", but handled properly it's needless to be afraid of either. You just have to take a few simple precautions, know how to handle them properly, and have a health dose of respect when using them. You don't need to be afraid of either, but you do have to respect them.
 
norbyx, does the other LiPo with higher capacity is good for this battery?
 
norbyx isn't on the forum. Higher mah just means longer run time. It usually also means more weight and more expense. You really can't have too much mah it just isn't worth it.
 
Thanks for reply. Spectra is on the way to me and I am thinking about modification. Usually, my "digging" day lasts 9-10 hours and is far from electric sockets and cars.
Rob (IL), what is your opinion, this mod is the good idea?
 
I see no problem with the mod. I run a 2200mah LI ION in my V3i and 12 hours is no problem. The 2900 runs 20+ hours. A 2200 mah lasts more than I will ever need in my ML SE. Critter has covered all you will ever need to know about Li Po batteries in various posts.
 
Rob (IL), thank you very much!
 
just calm the forum here is an answer for both sides,i have been in rc stuff for a long time,so after a little research,here is a possible answer...li-fe batterys (lithium phosphate) fairly new ,they are safer,they can be discharged all the way without any charging problems,the voltage charged is in the proper range,looks like the only problem is they need the right charger?????????do a search or visit one of the big battery or rc sites.....I think I saw a mention of li-fi batterys somewhere else on finds forums...hh
 
Well, I have done a choice: it is an idea to use 3x18650 LiIon batts.

Hi,
Just to pick up on an older thread:
Li-Fe batteries should NOT be depleated all the way, cause the cells will suffer.
Opposed to Lipos, their cut off voltage is around 2,7 Volts, Lipos should have their cut off voltage set to about 3,2 volts(if you deplete the cells to 3 Volts on a regular basis, cell life will suffer).
The advantage of LiFe packs is their different voltage configuration.
They come in denominations of 3,3 Volts - a 3S pack having 9,9 Volts -almost identical to the Whites rechargable NiMh packs or a 2S pack having 6,6 Volts which is a great replacement for the 4 c cell white pack.
Lipos come in denominations of 3,7 Volts - making a 2S pack 7,4 Volts (actually 8,4 Volts fully charged) and a 3S pack 11,1 volts (12,6 Volts fully charged),
The 4 C cell Whites 6 Volt pack is big enough to house either pack around 1800 to 2200 mAh plus a beeper warner which I can set to either 2,7 or 3,3 Volts very comfortably - the XLT AA cell pack gets a little crowded but it still works.
I am using both LiFe and LiPo packs in my XLT and my 6000 and the increased voltage of the LiPo packs has not caused any damage what so ever.
I would NOT advise to use LiPos in any rig underwater, cause if your seals go south, Lithium packs will short out and can burn under/in water.
Should you ever totally drain a LiPo pack, you can save it by charging it in the NiMh mode up to a tad over 3 Volts and then change to the balaced LiPo mode on your charger.
Cycle life will suffer but if your miles away from a store you gotta do what you can, to keep going.
Just my 2 bits worth
