Default How many lipo batteries do you own and how old is your oldest lipo batt?

Hello all,

For the past 4 months, I've purchased a total of 10 lipo batts because I don't like charging warm batteries and I don't like waiting. In addition, I don't like over using battery on any given day. I may use a battery twice in one day but that's my max.

So, I own 10 lipo batteries and my oldest one is about 4 months old. None of my batteries have puffed and I did crash one battery ($75 25C Lightning Power) but I squeezed it back to its original shape and it's fine.

At first, I charged it in a brick container but it works fine; it holds a charge and flies well. Also it seems safe when charging.

I have 1 3S 1800 20C Venom R/C, 5 3S 2250 20C Loong Max, 4 4S 2250 25C Loong Max packs. The Venom is a year old, 2 of the 3s packs are 6 monthes old and 3 of the 3S and the 4 4S packs are 3 monthes old. All still working well except the 1800 which is used only for testing.

I hear ya, waiting around for batteries to charge sucks. I have about 17 packs right now. The oldest is around 4 years - an ETEC 1200 mAh 2S that has lost some capacity but still works okay for a couple smaller planes and a micro heli. That pack actually was a 3S, but the tab on one of the cells corroded away, and so I made it into a 2S. Also have another from the same time that is still a 3S and I use for one of my transmitters.

Right now, I have 10 Lipos in the rotation. The oldest is about three years old and sags a little under load, but otherwise fine. I have a mix of Tanic, Apogee, and Polyquest, with one Loong Max thrown in for variety.

My lipo stack consistes of

2- Flight Power 6S Evo 25 2500 (about 4 months old)
4- Flight Power 3s Evo 25 2170 (Most around 1 year old)
1- Thunder Power 3S 2070 (1 Year old)
2- Thunder Power 3s 1320 (1.5 Years Old)
1- Max Amps 3s 1100 (1.5 Years Old)
2- Loong Max 3s 20C 2250 (1 Month Old)
2- G-Force 3s 20c 1800 (2 weeks Old)
3- G-Force 3s 20c 1300
4- Zippy H 20-30c 2100

Total of 21

I have only had one lipo go bad on me. That was a Flight Power 2170. I lost voltage under load and would not fly my T-Rex 450 anymore. I call up Flight Power and asked what they could do for me. In 5 days, I had a brand new pack show up at my door.

I have only bought high dollar lipos in the past. I bought the Loong Max and the G-Force after hearing good things about them. The Loong Max fly in my T-28 Trojan and the 1800 G-Force fly in my Mini Pulse. These packs only have about 8 cycles each on them. They provide plenty of power but I will have to wait and see if they have the same life span as the more expensive Flight Powers.

Approx. 40 and up to 4 years old. I mostly use A123 cells now so most of my LIpolys stay at 3.85 volts per cell at around 45F .

I have 2 3s Loong Max , 2 2S Loong Max and I have just bought a G3 Hextronic 3s ( took a risk as they claim they have changed the cells from the earlier versions which failed quickly).

I have had the Loong Max batteries for about 6 months, but have not put many flights on them. The 3S tend to go unbalanced by about 0.2V after each flight. However, so far they are still working well.

5 Zippy 11.1v 2200mah 20c batteries. I had 6, but an "unscheduled landing" damaged 1. I don't want to sit around waiting for batteries to charge, and I like to have the ability to always have one in the air if I chose to. I rotate them, and never fly twice in a row with the same battery. I've had 2 of them for 4 months, and the other 3 for 3 months.

I'm afraid to count how many I have... But I do know it is not enough!

My oldest is a GWS 2s 1150 that is about 3 years old now. Newest is 3 25c 3s 2100's Cellpros' from FMA, just soldered the Deans on them last night.

LOL -- I'll have to go home and do a physical inventory to be SURE, but here's a first stab:

I currently have 15 LiPos in rotation -- several different brands, shapes, sizes, number of cells (2s, 3s, 4s), and mAh sizes (from 800 mAh, up to 3150 mAh).

One is having a problem right now -- the balance leads keep mysteriously becoming "unsoldered"... I think I'm going to solder it one last time, and goop it with cold melt hot glue...

Additionally, I have 7 brand new (never used) LiPos "in stock" -- as inventory for my little "hobby-business"... If they don't sell, I'll end up using them myself.

My oldest battery is a Tanic 3s 2220 mAh LiPo that I first used on November 1, 2005 -- it's the second LiPo I ever purchased. It currently has 90 cycles on it -- 25.27 hours in the air, for an average of 16.85 minutes per flight. The maximun flight with this battery was 40 minutes on May 18, 2006, and the average cost is $0.48 per flight. This battery is still going strong!

I've sold 7 of my LiPos to people who needed a LiPo NOW -- all were in excellent operating condition when I sold them. This includes the first LiPo I ever purchased (a Tanic 3s 2220 mAh Lipo) on April 14, 2005.


I've lost 7 LiPos to various reasons:
  • 2 LiPos lost to over discharging -- it happens when I'm using an ESC with a low voltage cutoff set to SOFT (I like HARD cutoff, because I KNOW when the battery is low). Since I discovered the ESC LVCs were killing my LiPos, I fly with a Low Voltage Alarm, and no longer overdischarge my LiPos.
  • 1 LiPo lost to a horrible crash... It was a $90 4s 3150 mAh LiPo... It was the very first flight... :o (See picture, below.)
  • 2 LiPos were "puffed"... I ordered two Apogee 2s 2200 mAh LiPos from Tower Hobbies. One arrived in the mail in "puffed" status. I asked Tower Hobbies -- they said to throw the "puffed" pack away, and they'd send me a new one -- they did! I used the packs ONCE -- when I reched for them a few weeks later, they were BOTH puffed -- but still showed a good charge. I gave them to SmokeJohnson (here on WattFlyer) to do with as he pleases... :o
  • 2 LiPos just suddenly had dead center cells one day that I reached for them... Both were Tanic 3s 2220 mAh LiPos. I e-mailed Tanic, and Brian offered me NEW battery replacements at a greatly reduced cost... I have not yet taken him up on his offer... :o

question ? do the thunder power extreme lipo's use the same cells as the flightpower. as they look the same and TP use the same sort of wiring down the side of the pack. also has anyone seen a cheep lipo that looks anything like the older TP packs.

None. They're too finicky and high maintenance to be worth the benefits, IMHO. If I should ever want something that can react violently if not handled correctly at all stages I'll get myself another woman.

I think I can rattle them all off the top of my head. In the order that they were purchased:
  • 2 x Loong Maxx 2250mah 20C 3S: One is still new in the packaging; the other, I've been cycling in my Slow Stick for about 4 months now, and have had zero problems.
  • 2 x Zippy 1000mah 20C 2S: I've been cycling both of these continually for 3-4 months, and have had zero problems.
  • 3 x Zippy 1300mah 20C 3S: Been using all three of these in several of my planes for about 3 months, including my 107mph Delta Demon, and have had zero problems.
  • 4 x Mystery 900mah 15C 2S: Highly underrated battery. These are GREAT for small foamies and easy flying Slow Sticks. And best of all, they're less than $8 shipped. I have 2 new in the packaging and 2 that I've been cycling constantly for about 3 months. Oh, and I've had zero problems with both of them so far.
  • 1 x Mystery 2100mah 20C 3S: Just got this one a couple weeks ago and haven't actually tried it yet. Looks nice, though.
  • 1 x Mystery 1500mah 15C 3S: Only flown this one once, but it charged to full capacity and flew like a champ in my yellow Slow Stick. Hopefully it will hold up as well as it's 900mah 2S little brothers. Great buy if it lasts.
  • 4 x 50mah 1S Havoc Heli LiPos: Ordered me several of these to tinker around with since they were so cheap. I used one of them to replace the capacitor in my Air Hogs Aero Soar (only got about 45 seconds flight stock--was crap), and now I can fly my little indoor plane for over 10 minutes at a time. I've cycled the one that I'm using at least 30 times now, and it still perks right up every time.
That's all I've got for now, but I'm looking to pick up a 4S - 6S battery for the gas->electric conversion I'm working on now. Either that, or I might just hook up my two Loong Max 3S lipos in serial and use those. Flights might not be very long for a 2250mah 6S pack, though. Hmm....

Default Lipos

I have a total of 24. All are Electrifly from 7.4 to 14.8 volts, 1200 to 3200 Mah. I fly almost every day and have never had a problem with them. The oldest was purchased 3 Jan 06. Severl have survived serious crashes with no damage. I time my flights and never fly to voltage cut off.

you get a small sensor that fits onto the battery this is only really any good for nicad and ni-mh. but if it falls out the charger wont stop charging + the battery has to be cool before charging. i had one when i did rc car racing. so if you tried to charge a battery that had just been used the sensor could not be used. it is only of some use if you have loads of packs. saying that i still have almost 30 packs from when i was in to rc cars. and if you think my lipo collection is over the top. well at one time i had around 50 rc cars. i have just put in the bin 10 mains 30 min slow chargers. that have been in a box for the last 14 odd years lol. some of my cars were 7 tamiya Porsche 959 15 tamiya grass hoppers 3 clod busters. 2 rough riders. i go over the top on all my hobbies

If you hook up the Triton Thermal Probe (sold seperately), the Triton can monitor the temperature of your LiPo pack... If the LiPo pack gets too hot, the Triton will stop charging it.

It's a safety feature that I've never used... :o

For what it's worth, you should never charge a warm LiPo... Even if it just came out of an airplane (or car) -- give it a few minutes to cool first; then put it on the charger.
