Many users are confused on LiFE battery technology. Wondering if you need to use a regulator or not? Also about using 1 battery for an entire plane?
LiFe batteries are safer to use than Nimh or Nicad 6v batteries. This video explains that and more about LiFE batteries.
It also goes into detail about redundancy for your RC plane and how to set that up using a power box.

This is a great video with excellent info

@rhshel Год назад

outstanding video. Makes very good sense! Love to investigate the power boxes you mentioned.

@tonyantoniou2853 11 лет назад

Very good information about Life batteries thanks.

I was on my school's Xtreme Bots battlebots team, and the year that we went to the tournament and guys were running with LiFE batteries it changed the game. Lipo batteries are banned in my area because of the explosion risk, and these were a great replacement. The first group to do it duck taped them and got accused by a few people who saw it of using lipo batteries. We ran LiFE the next year and our two teams took first and second. All the power none of the danger.

With Life's it's kind of hard to tell by voltage, however, I've foudn that once mine hit 6.1 with a load on them (load tester) it is time to stop flying. the best way is as mentioned - fly about 5 flights (any number of flights SAFELY under the assumed limit) and then charge the battery (not balance this time, just charge) and see how many AMPS are put back in.

Great information! Thank you. I hope to see you guys at Joe Nall 2015!

@stuward3046 7 лет назад

Your video on prop balancing is very good. But I could not find the video on finishing the prop so that there is no more tape on it. Can you post a vid for that Stu

@trpastor 11 лет назад

Hi Patrick, - yes, this is a good point and is somewhat mentioned in the video. In my experience manufacturers recommendations are in the "safe / cautious" range. I think they are aware that is they SAID "7.2" then some people would put a 7.2v battery on, not knowing that it peak charges much higher and would fry the electronics. Therefore, they give 6V knowing that at the MOST people would interpret that as a 6V battery. Therefore, 7.2 is safe and they know that.

@trpastor 11 лет назад

Very welcome guys! It makes sense when it's explained but can be confusing if you've never used or know much about LiFE batteries

@johnr.timmers2297 3 года назад

My Xtreme Bots team went to a competition where the winning bot (who kicked our butts) was way powerful thanks to LiFe batteries to the point where referees inspected it to make sure they weren't using the then banned LiPo batteries. By the time my senior year came around, everyone was using LiFE in their battlebots, and that plus better designs led our two teams that year to taking both first and second (the fight between the two of us was BRUTAL, and thanks to our teacher's support we all decided on not ever tapping out. Eventually my team's top shell came off, spilled her guts, but we kept fighting until our weapon chopped the main power cable.) Edit: To explain, due to weight limits, Nicd was cumbersome to use, but with LiFE we were able to get more bang for the buck and didn't have to worry about draining the batteries too fast

@3DMOFO2020 7 лет назад

Will the LiFE 1450 be good choice to power up my 40 size 2-stroke powered 3d profile plane? I use digital servos on the tail and have 3 regular standard servos on the wing and for throttle

@jacobhendrickson8935 10 лет назад

Great info. I had called Traxxas and asked if it's ok to use a 2 cell life battery as my receiver pack and the guy said no. Well I purchased one anyway and thought well ill get a bit better performance and hope for the best for my receiver and servos. Now I'm a little concerned am I going to lose any performance? I've always wondered why most speed control BEC s only deliver 5 and 6 volts when a 6 cell pack peaks at 7.2 volts. You would think they would make the speedo BEC more like a 6.5 volt standard. Anyway thumbs up.

@RomansFiveDotEight 8 лет назад

Hey Tim! So my current build (and what will be my first RedWing RC order! Servos, batteries, power board, etc...) is going to be a Great Planes Escapade 30cc ARF with the DLE35. The plan is a yellow power board (The balancing feature of the black doesn't seem like a very big deal to me; should I consider it more strongly? Seems like unnecessary extra weight). The one with the LCD screen. And then two batteries; so here's my question: 1450 or 2100? I know in the video you suggest a pair of 1450mAh batteries for a 30cc plane. Is that a pretty hard and fast rule? Will a light and mildly overpowered airplane like the Escapade that is NOT a 3D model really benefit from the lower weight? Would there be a significant disadvantage to running a pair of 2100's? I'd love to have peace of mind and to be able to fly all day without hugging the wall at SLRCFA to recharge batteries. What are your thoughts?

@timpastor4304 8 лет назад

+Romans Five|Eight You can certainly go larger, and I would look at the specs online and see if you feel you are willing to pay the penalty. My thoughts are on a non 3d plane that is known to fly well you won't feel a slight increase in weight. About the only time you'll slow a plane like that down to feel a negative impact is on landing. But I do NOT think you will be unhappy with it. However please note if you are using the YELLOW board and LIFE batteries you must use the 3s (9.9v) to be within the minimum INPUT range on the yellow and black boards. they both have a regulator, and most regulators automatically drop the voltage that you input. So if you start with 6.6, it will drop it to an unusable output more than likely and COULD be dangerous if you drop below the basement voltage for the board to operate on We pair our boards with recommended batteries though so if you follow one of our packages you can't go wrong

@RomansFiveDotEight 8 лет назад

+Tim Pastor Thanks Tim! I didn't realize that!

@trpastor 11 лет назад

That is why in the video it SAYS "IF you've used 6v batteries in the past and feel comfortable with them, then the Lifes are even safer, as they immediately descend to 6.6v (Their nominal voltage) while a 6v nimh/nicad peaks at 7.2 and stays there for a while.

@shanec4441 8 лет назад

Is that connector a universal style plug that will work with Futaba and JR ? .

@cugglester 11 лет назад

Hello, would it work to put a LiFe Source battery in my tv car? Or are the LiFe batteries only for transmitters?

@warbirdkid 10 лет назад

When do you stop flying to charge the 6.6 in other words when should you stop at a safe point

@sinuemedina2550 4 года назад

Im runing 7 hitec bs 5485 digital servos on my plane but i dont want to fry them, what life battery donyou recomend?? 2000mh 6v??

@patrickrede 11 лет назад

When the DLE manual says 4.8 or 6v Nimh, are they aware that a 6v Nimh battery peak charges at 7.2v? Why does there manual say no more than 6v to the CDI? Confusion. I have flown 6v Nimh and never had a problem with receivers or regular servos.

@ericmdk 10 лет назад

Fried a spektrum s8000 servo with a life battery. Using a 6v regulator now.

@johnweeks1713 5 лет назад

ericmdk lol its spektrum what did you expect

@plasticbaldy 10 лет назад

Is there any reason why I can't use my 2 cell LiFE battery to fly my model with a brushless motor that I previously flew with the 2 cell LiPo >

@timpastor4304 10 лет назад

it's not quite as much voltage so it won't probably have quite as much power but may work. It's 6.6v peak. 2 cell lipo is 7.4.

@trpastor 11 лет назад

6v Nicad/nimh Peak charge at 7.2v. I do not think it says they peak charge at 6v anywhere. It says they slowly drain to 6v Also it mentions that 4.8v nicad/nimh peak charge to 6v. Maybe that is what you heard. Point being, the 6v peak charge is still close to the peak charge of 6.6v on a Life battery

@jacobhendrickson8935 10 лет назад

My only question on LiFe battery's is storage voltage. Lipo everyone seems to agree on around 3.8 per cell. But with LiFe what is recommended for storage.

@jacobhendrickson8935 10 лет назад

Great video. This video is the reason I started running LiFe battery's in my nitro vehicles. They make the best receiver pack ever. I can run my revo 3.3 tank after tank for at least a hour. I'm sure I can run even longer and this is on a 700Mah zippy life battery. Less than half the size of a 5 cell Nimh and light as a feather lol. I switch to my second battery after a hour or so to be safe but when I charge I always see I had more room to keep the first battery in. But I still can not get a solid answer for storage on these battery's. What voltage should I store them at??? Anyone

@jacobhendrickson8935 10 лет назад

I finally found the answer. I found hobbico s life source lithium iron phosphate battery instructions. In these instructions it does state that when you are going to store long term. Charge battery fully then discharge to 60 to 75 percent of total capacity. It specified long term as like 6 months or more so evidently this must not be needed for shorter storage times. I myself will still keep mine around 65 percent when not in use to ensure my battery's are maintained the best possible. I hope this helps the next Obbsessive compulsive person like myself to have the answers they want. If you want a copy of these instructions. Search ( Hobbico LiFe source lithium iron phosphate battery instructions) this is 4 pages of LiFe source literature. Thanks Jake H.

@ericmdk 10 лет назад

A lot of these voltage comparisons coming off the charger are not as important as voltage under load differences .

@cafersas 6 лет назад

so a LiFe battery pack 6.6 v in theory wont burn my receiver that work between 4 and 6.5 volts?

@camelCased 6 лет назад

Good quality receiver should have at least some minimal internal voltage regulation that should tolerate higher voltages to some extent. Also, during work, the voltage will drop slightly, so your 6.6 can easily drop to 6.5 immediately when any load is attached.

@PhilipAlonzo 6 лет назад

I use 6.6 on all my spektrum recievers no regulators

@johnswan6161 3 года назад

Why not make the batteries with the xt60 connector to match the power box xt60 connector ???? Would make life easier...

@terragady 5 лет назад

Really, you use such lower end multimeter ? Guess work would be better

@dwkach 10 месяцев назад

He not entirely correct on ignitions. Older ignitions explicitly state 4.8vdc battery. That means a 4 cell nicad type battery. More recent ignitions allow higher voltages all the way to 11vdc. Read your ignition module before connecting any battery.

@tonyantoniou2853 11 лет назад

Just listened to this again and first you say nicad/nimh peak charge at 7.2 and then 5 mins later you say peak charge at 6.0 !?&@£ ???!! Help.

@TOMVUTHEPIMP 9 лет назад

Just use NiMH. They are cheap, and they work.

@timpastor4304 9 лет назад

NiMH, you have to use a regulator, or deliver over voltage to your servos at first, then lagging amounts later. If you are looking for consistent performance they are not ideal unless used with a regulator, and then you have one more potential point of failure

@TOMVUTHEPIMP 9 лет назад

Tim Pastor Never used any regulator.
