battery

What I would like to see is how flite test disposes of old, severely damaged, minor damaged, and simply demolished batteries. The internet has loads of stuff regarding salt water bath, discharge to '0' volts per cell, etc. What do you guys do for the battery that is (fill in the blank). Would...

Hey Guys, I'm new to the forum and need a we bit of advice. I'm in process of building an Octo-copter with the Electrohub booms and plates, though I have no idea on how I'm going to go about soldering/connecting all the components together and what battery(s) I'm going to require. Run down...

Hi, everyone, I've seen the beginner series and I got really confused on the battery episode. I didn't understand about charging them, mainly. The battery I want to get for my ft old speedster is a turnigy 1000mAH 3s 20c lipo pack. Could someone please tell me stuff like flight time, what...

Newbie questions...Running a dji flame wheel clone, 2830 1000kv motors, and 30a escs with a 3s 3300 gen ace, 10x5props and getting about 10mins flight time.l want to increase the flight time, obviously a bigger battery will help. Do i just go 4s 3300 or 3s 4800 or 4s 4800? Or just buy a spare...

I have a motor that takes a 2S and 3S batteries. Will the motor react any differently to a 3S than it does a 2S? Is there a difference in flight time? I realize the 3S has higher voltage but how does that play into the performance of the motor? Thank you

Hello all. I just got the Aprentice S 15e after owning the mini super cub and the parkzone um p-51d. The DX5e is however, my first full range digital tx. All has been well after recieving the RTF setup on friday. I flew it and it worked. Now, however, the radios trims do not function or even...

Hey everyone! A few months ago, I built the FT rotorbones tricopter and have had a blast with it. One issue that I have is flight time. Using a 2100mAh 3s battery, I only get between 5-6 minutes of flight. Does that sound low, and if so, any suggestions on how to increase the flight time...

Hey everyone, my friends and I are head over heals excited about getting into flying RC planes, but we have a major impediment... We live in Iceland. There are some problems with living in Iceland, mostly if you want something that you can't buy in the supermarket, it's very likely to be hard...

I recently found that I had puffed the 3 cell battery from my stock Super Cub LP. Are there any specific disposal methods that I should take to avoid a house fire or some other dangerous event? Also, I plan on getting some new 3s 1300mAh batteries from hobbyking, but I believe those come with a...

Today I was intending to maiden the scratch build of the FT-3D. It was a normal day, but it turned out to be my worse flying day out of my 'career'. I had strayed from the recommending build, deciding to use a smaller propeller, .0947EF prop, than the recommending 1200kv motor. I only have the...

Bubble, Zap, Puff, Bang and Blow. Your Tales of a Little More Than a Puffy Battery. Hi Joey here from R/C Engineering Magazine.Recently on our page I had asked viewers about their stories of batteries incidents ending in fire and explosion! I wasn't expecting very many responses, but boy was I...

The nice guys at Scorpion sent me one of these cool gizmos to review. I could have just done a boring bench test but decided a real world demonstration was more fun. Hope you like the video...

Hey guys, I am putting together an FT Flyer, but I'm having a problem finding a battery for the Turnigy 9X I got. The AA pack that came with the TX is okay, but my TX is constantly beeping -- apparently the AAs I had weren't as fresh as I thought. I'm really hoping to find a battery I can use...

I have 2 850mAh 3 cell batteries from LazerToyz for my FT swappables. Can these be charged with any LiPo charger, or do I have to buy a specific brand? I would like to use the LiPo charger I have from my Super Cub, but I'm not sure if you can safely charge between brands.

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.
