    damaged 3S LiPo

    hehe, no I'm not that desperate ;) (yet..)

    damaged 3S LiPo

    ... actually after further research - the gas behind the puffing is oxygen. Its source is anode degradation. So poking a small hole and resealing it may not be that crazy of an idea, because you wouldn't introduce anything that wasn't already there (drain oxygen, introduce air). The dangerous...

    damaged 3S LiPo

    ok, after reading the referenced thread, here is my understanding: 1. Puffiness = gas buildup. The gas is methane and ethane. 2. The danger is not the gas itself, but that the pressure will eventually burst the sealed cell. This hole allows oxygen to enter and a reaction with lithium ensues. I...

    damaged 3S LiPo

    got the bad pack removed this weekend. The two soldering guns technique worked (sorry, no pics :( - had my hands full!). The most difficult part is separating the soldered pieces without a second person, but it can be done. The interesting part was - the bad pack is completely flat - like a...

    damaged 3S LiPo

    Some news: I cracked open the bad LiPo :eek: The white wire is connected to the big red (+) wire - so it is positive, not ground. Checked each cell directly with a multimeter, but as before - 2 cells ok, one compeletely dead. As in 0V, measured directly on its terminals. Then, I tried to...

    7" 800x480 LCD selection question

    Thank you all for your replies! I've looked at some of these, but I need 2.4G... Also, this is supposed to be kind of a cheap build. I've settled on BOSCAM 2.4G RC802/TS321 TxRx and need a monitor to match.

    damaged 3S LiPo

    No worries :) Still thinking. I was gonna try to charge it with a hacked together 3S->2S adapter, but J.James is onto something - how can it be exactly 0 volts? Good thought! I'm gonna peel off the wrapper and measure on the cell directly. What is the significance of the coloring of the...

    damaged 3S LiPo

    I like this idea J.James. All I'll have to do is to swap out the balance plug for a 2S PS. Just re-checked the balance plug. It goes like this: Grey--4V--Grey--4V--Grey--0V--White

    damaged 3S LiPo

    Is this not something commonly done? I just hate seeing 2/3 of a good battery go to waste...

    damaged 3S LiPo

    So I have an original phantom 3S LiPo that does not charge and outputs ~8V. From checking the balance plug one of the cells (out of 3) is dead. Can this battery be hacked into something useful? Like a 2S for example?

    7" 800x480 LCD selection question

    Hello friends. I'm in the process of selecting an LCD for my FPV needs and I've settled on 7" 800x480. Ebay presents the following cheapies. However, other than the fact that they are cheap, nothing else is really known about them. Are they bright enough for outdoor? Do they blue-screen...
