New charger.
Hi all! I'm very new round here so please be gentle! I also have a question regarding Lipo technology, and specifically my charger...
I'm starting using Lipo batteries now, for my rock crawler and my helicopter. I would also like to use Lipo batteries in my sons Losi DT sometime in the future..
My question concerns my charger:
I recieved my new charger yesterday, its a Dynamite Passport Ultra, capable of balance charging Lipo's and also charging/discharging Nicad and Nimh batteries. (I've decided I need to take much better care of ALL my batteries!)
One of the settings is called the "Capacity cut off". Obviously I've set this (for now) to be the same as the capacity of the battery I'm charging, whether its a 2200mAh Lipo, or a 1600mAh Nimh reciever pack etc...
My old Fusion charger never had this "Capacity cut off" setting before? I thought the charger would automatically detect the pack becoming charged, peak, and then shut down/go into trickle mode.
Any ideas on why this setting is there, do all Lipo chargers have it? The setting is also applicable for Nicad/Nimh charging.
Another quick question: I charged my 1st Lipo pack last night. I can honestly say I don't think I've been as paranoid before in my life! I think it was all the scary videos on YouTube of people doing franky VERY stupid things with these batteries...
Anyway, I set the voltage/series cell count(3S), the charge current (I charged a 2200mAh pack at 2 amps), and the capacity cut off (2200mAh). It took about 1.5 hrs to charge the pack, and it was very interesting to watch the charger balancing the cells. When the voltage in the cells reached 4.2v it shut down automatically.
The battery didnt get warm at all. Is this normal? I thought a little bit of heat may get generated by the charging process. But this is the 1st Lipo battery I've ever charged, so I'm not sure....?
Any ideas good people?
Steve.
