The most necessary factor is you possibly can't go together with too low a discharge C score or you'll harm your battery and possibly your ESC . Think of increasing the RC Lipo battery capacity similar to putting a bigger gasoline tank within the RC automobile. Now that I actually have bored you to demise with LiPo RC battery basics, time to get into the primary topics at hand.


Larger electric RC helicopters are power hungry monsters; some peaking over 8000 Watts on the rotor shaft! If you can keep your LiPo's happy in a giant heli, you possibly can hold them happy in absolutely anything. I've been into Li-Po powered RC flight for the higher a part of eleven years now, and have learned so much about this wonderful powering method in that time frame.


The cell rapidly ballooned out, burst, and vented oxygen & flammable electrolyte but never caught on fireplace. These LiPo pouch cells also enable for extra thermal enlargement and even gassing due to the flexible pouch over a steel can that most Li-Ion cells are encapsulated. So, they'll additionally been considered as a security feature to some extent. There are a couple of down sides with LiPo batteries nonetheless; as soon as once more proving there is no perfect RC energy answer .


LiPo's are very good at maintaining a consistent voltage/energy output as they discharge. The voltage/energy drop nonetheless when they are reaching a totally discharged state could be very quick when in comparison with NiCad, NiMh, or PB. LiPo batteries have 5 major issues going for them that make them the optimum battery selection for RC planes and even more so for RC helicopters over typical rechargeable battery varieties such as NiCad, or NiMH. They are the main cause electric flight is now a very viable possibility over gas powered models.


The primary advantage to a delicate case is clear - much less weight and a smaller type issue as there isn't any bulky case across the cells. On the optimistic aspect, if it might have burst into flame, I would not have this picture to show the 'guts'. I solely did this because I dropped this heavy 6S 5000mAh LiPo pack on the hard concrete floor (yes - very dumb & costly butter finger moment) and one cell was broken within the course of. Lesson realized, do not carry extra LiPo's than you can safely maintain. If you are questioning what the burnt gap is within the heart of all the plates, I purposely drove a nail via this cell to discharge it quickly & watch the fireworks.


Lithium Polymer Ion batteries present the efficiency of the Li-ion in a thin or moldable package deal. They don't use a unstable liquid electrolyte and may sustain significant abuse without explosion or fireplace.


Believe it or not, LiPo RC battery care & understanding entails more than just cost, use, recharge. Harding Energy, Inc. provides all kinds of Lithium Polymer cell choices, with a number of certification levels. To make the process easier for our clients, we now have uploaded the following PDF’s for our clients to evaluate and select the battery that can match their wants.


Once they reach the end of the take a look at, the cells are decomposed, unrolled, and the failure vector evaluated. Overall I was impressed with the level of undertaking and verification.


This presses the cell down onto a size of triangular metal that causes the cell to fold at gnarly angles. Needless to say the carnage was epic and the chambers were coated within the soot of failed cells. This machine would take bare cells and mechanically minimize and slip on the heat shrink label.
