battery

Hello, everyone. I got a Zippy Battery, 25c 2200mAH, 3Cell. One of the cells are vitually dead (3,69V; 4,20V and 0,26V). So I found this video (in Portuguese, because I'm a Brazilian) where a guy teach to recover a dead cell using other battery. He put those together and let the cells balance...

Hi everyone, I finely finished my tri build and have it flying reasonably well. My problem now is the low battery alarm is not working. I have it set * 138 but even when the KK2's (V 1.6 downloaded from HK web site) readout is down to 11 volts it does not beep. The speaker works OK when tested...

I am still a bit of a newb to the hobby right now so I have came across one question regarding LiPo discharge. I have read all around that a healthy voltage to discharge a Lipo to is about 3.7v, nominal voltage (Not under load). So as a beginner, I have a battery alarm on my tricopter that...

Hello, i'm new to quadcopters and while i've read a lot and watched a lot of videos i don't have the experience of different combinations to get what i want first time so i was wondering if you guys could give me some advice :) I'm in my final year of electronic engineering and i'm building an...

I only heard about these recently. I'm really surprised these aren't more well known. Anyway I made a quick video on them. Enjoy.

Hey Guys! I know you're suppose to charge your Lipo batteries to no more than 4.2 V per cell (so for 3S, its 12.6 Volts), BUT is there a way to SAFELY charge a Lipo battery above this limit? Thanks!

Hi, I am 13 years old and really want to get into the hobby of flying RC planes. The plane I want is the Corsair from Hobby King (http://www.hobbyking.com/hobbyking/store/__18035__Micro_F4U_5NL_Corsair_550mm_PNF_.html). It says I need a 4 Channel Radio and 450mAh 2S Lipoly Battery. The...

Hello all, forum newbie here so perhaps I should introduce myself first. My name is Paul, I Love flitetest (who doesn't) and have been into RC for some time. I now (mostly) know what I'm doing (at the expense of several planes) and like to dabble (what a strange word) in other things such as...

I have recently decided to start building the swapables with the beef setup. I have the esc, motor, servos, and everything else but the battery. After looking at both the spitfire and baby blender build pages, I notice that the recommended battery is a 1300mah 4s, however when looking at the...

Yesterday was my first successful flight. I was flying the Old Fogey. The flight only lasted about 3 minutes then the battery seem to lose power. When I took the plane into the garage I noticed the motor was pretty warm (I could still touch it) and my LiPo was pretty swollen and warm to the...

I was wondering what some good sizes for props would be which i can use on a range of different planes. I would like to be able to swap different props in and out depending on what i want and i was wondering what some common sizes would be to purchase. I would also like to have a range of...

Swappable overheating I was wondering if anyone else is having problems with heat in the swappable power pods... I've ran into several instances recently on the FT3D puffing batteries, ect. I've done a simple fix by adding an "air intake" on the side of the fuse through the pod and that seems...

What charger do you use make and model? How do you store your batteries when charging and when not in use? :)

Hey Guys! I am new to flitetest forums. I just purchased a parkzone extra 300 and am in need of some help.. I am an intermediate skill pilot. On the maiden flight I dont think the battery was in the correct location for CG and the plane tipped over and took a nose dive at 20ft. I am an...

Hey guys, I am building my first balsa plane(photo and specs in attachement) and i am new to choosing motors,props,Esc,batteries myself as i have always bought bnf or plug and play airplanes. Could someone please help me find a good setup (electric) for this airplane ? Can be Hobbyking or...

Hi everyone, Does someone know what I could do to help the batteries on winter time. I want to fly but at -20 celcius it's a bit hard on the batteries... Should I make a hot sleeve or anything similar?

Hey Guys, New to the forum, but have been a long time Flitetest viewer. Ive recently got into the hobby and am itching to learn! One of the things I am REALLY wanting to understand is Batteries... What do all the numbers and varieties mean... Anyone willing to explain it to me...

Hey everyone, I've got an idea for a DIY Battery Discharger since my HobbyKing ECO6 50w 5A charger can only discharge at 1A and I'd like to charge and discharge in bulk per YCopter's parallel charging/discharging tutorial. I just want to make sure my logic is sound before I post an article...

HI everyone, I was wanting to get some information on Lipo and charge levels please. I am a total noob to the electric side of things, and only just returning to the hobby after 20 years absence. So if any one would care to share their wisdom, that would be much appreciated. I have been trolling...
