wesley Posted February 12, 2013 Report Share Posted February 12, 2013 Just wondered what other PW members are using ?? I use YUASA 12v 17ah (lead acid) type that last a whole day but are very heavy to transport. Is anyone using Li Po (Lithium-ion polymer) batteries They have the latest Li Po batteries at my local motorbike shop but expensive at £110 but incredibly lightweight. Thanks Wesley Quote Link to comment Share on other sites More sharing options...
gilo17 Posted February 14, 2013 Report Share Posted February 14, 2013 (edited) I was going to ask the same but I found a 12v 12ah golf trolley battery in a layby at work that was fully charged so never got round to it!

THE GRIFF Posted February 15, 2013 Report Share Posted February 15, 2013 I have a 15ah wildhunter lithium battery that I bought for a magnet, the magnet is a standard cheap one that I got secondhand. I tested it at the weekend and it ran really slow (about 22rpm rather than the usual 40 rpm) with the lithium battery even though it was fully charged, I presumed the lithium battery was running slightly less than 12v which would of explained it, but when I went to charge it back up again to test the voltage the battery wouldn't charge, when I tested it with the volt meter I couldn't even get a reading. So at the moment I aren't sure if the battery was faulty to start with and that's why it was running slow or wether these lithium batteries run less than 12v which could be a problem with some magnets. Sorry it doesn't answer your question, but I am sure I will of confused you even more, I will post the outcome of my problems when I have the answers myself.

Thanks Wesley People seem concerned with the weight of a battery! What about if you shoot a sack full of pigeons? Average weight of a pigeon lets say 14/18ounces! So your red letter day including squabs will be close to a 100lbs!! A normal rotary 12v 7.5 amp battery weight 6lbs or 8-10 pigeons The one that costs £115.00 will equate to around 3-4 pigeons So you can shoot 104 pigeons and not be puffed out…..

kdubya Posted February 15, 2013 Report Share Posted February 15, 2013 jeez them wildhunter batteries aint cheap are they? may be better spending the money on a lightweight rotary that will run all day on a 4AH sealed lead battery and you wont need to worry if your going to burn the house down when charging one overnight?

TEH The idea is to make life as easy as possible to get to where I am going in one trip, if after an hour I have to pack up and move 2 feilds over then the lighter and less bulkier the better. I don't mind making 2 or 3 trips back. Quote Link to comment Share on other sites More sharing options...

If you have over discharged the lithium battery you wont be able to recharge it in its current state, as the lipo charger relies on a voltage level from the battery to initiate the charge. This is a safety thing (google lipo fires). I assume it came with its own charger, this type of battery is used in the RC world due to its light weight and high capcity. I fly RC helicopters and shoot.. Edited March 22, 2013 by Agent36 Quote Link to comment Share on other sites More sharing options...
varminter pb Posted March 23, 2013 Report Share Posted March 23, 2013 I'm glad someone's asked as I was thinking of trying my newish but redundant Deben lithium ion 17ah battery when I finally get a magnet. Bought it initially for my Lighforce 170, but in the end stuck with NV in my CF's. May just buy a lead battery from the sounds of the above.

whitey10765666 Posted March 23, 2013 Report Share Posted March 23, 2013 I use the lipos on my flappers, they work absolutely brilliant all day by remote control with hardly any power loss, i think it would be a different story on a magnet especially a wiper motor, Quote Link to comment Share on other sites More sharing options...

THE GRIFF Posted March 23, 2013 Report Share Posted March 23, 2013 Just a quick update on my previous post, I sent the wildhunter lithium battery back under guarantee for an exchange, it was faulty. These batteries are protected from over discharging and stop working with 20% of the power remaining to protect the cells, you can't overcharge them either if you use the correct charger as it cuts off. The new 15ah battery works fine with my pinewood rotary and starts off at 38rpm, dropping to about 32rpm after 3 hours, it hasn't started to go any slower than 30rpm even towards the end of a 8 hour session in 40mph gusts of wind using dead birds and the battery was still showing half charged. I would think this battery will last a 12 hour + session in the summer. I also have a chineese 4800mah lithium battery from the bay I use for my flapper used with a random timer and it works fantastic, very small and light and powers the flapper for days off one charge. I am very wary when I charge it because of the stories of them setting on fire but upto now it's been fine, I do take it into work to charge it so I can keep a close eye on it. Regardless of what some people might say, using lithium batteries rather than lead acid batteries does make a lot of differance to the weight of your gear when carrying it along way.

aauser Posted March 24, 2013 Report Share Posted March 24, 2013 Just a thaught but what if you shoot a low bird and up in smoke a bloody expensive battery with stray shot ,we know this happens so for me it's a 22ah battery for 32 quid that runs my rotator all day dead or paper birds .for sure weight is an issue but you can always do two journeys Quote Link to comment Share on other sites More sharing options...

I would like to think I didn't get that excited and carried away I shot the battery, what would you do if you are shooting near livestock or had a building near you, I am sure you would not shoot these if you were aware they were there, but saying that I am sure most if us have peppered decoys with shot whilst shooting low birds.

Yes, for £32 for a gel battery, think I'll buy a gel, no issues over length of use either with a full charge Quote Link to comment Share on other sites More sharing options...
