TURNIGY® Batteries explained
*Cycle Life results from discharging at full C rate to 3v. End of life when battery has 80% capacity.

Räknas en cycle från 3v och upp till max, blir det då en halv cycle med en halvfull ack.
End of life when battery has 80% capacity - är den död efter det.

Tja vad ska jag svara på det! Det står ju så där i allafall 8)

Ni måste ju skilja på spänning (Voltage, V) och kapacitet som batteriet har (Capacity, C), två helt olika saker. 8)

Man kan dra ner en LiPo till 3V under belastning, helst inte lägre (har jag förstått).
När acken inte längre belastas och återgår till normal sval temperatur (typ +20?!) så skall spänningen inte vara under 3,25V. Detta har hänt mig, då låter man acken ligga en vecka eller nåt så brukar den komma tillbaks till över 3,25V (vart med om att acken kommit tillbaks til 3,6V fast den var 3,1V vid svalt tillstånd efter användning. Funkar kanon än.

Men åter till det ni pratar om... jag förstår inte heller nu längre... :mrgreen:

Dagens ackar räcker det att bara plugga in dom så är dom fullt laddade.
Undrar viken laddare som klarar att leverera 12C till acken.

G6 BATTERY SERIES
The next generation of LiPo battery performance is here!
Up to 60% more power, 100% more cycle life & 12C charge rate

Thunder Power RC is proud to announce exclusive Generation 6 (G6) chemistry that delivers the lightest, most powerful, longest lasting and fastest charge rate capable LiPo batteries yet. G6 series batteries offer the highest energy and power density in high-discharge rate capable LiPo technology, weighing less and delivering up to 60% more power than previous and 100% more cycle life than recent generation LiPo batteries. That means more power at less weight for up to an incredible 600+ cycles while also being capable of technology-leading charge rates up 12C* for charge times of as little as 5 minutes or less.

Bra filmer om LiPo's. Man kunde ju de mesta efter att ha laddat LiPo's i några år, men nåt nytt lärde man sig nog. =)
För den nye är det bra filmer. Snubben kan iaf snacka! Sett 2 av 6... tar ju sån tid att lyssna/se.

Ja, när man började med lipo var det nog mera att pröva sig runt med dom nya ackarna.
Nu behöver man bara se och lära sig på nätet, tänk vad det har gått fort på så kort tid.
Nätet och all info når fort ut till läsarna när folk är snälla och lägger ut filmer.

Se inte på denna film. Riktigt skitdålig. Täcka över två sista siffrorna och sätta en punkt mellan de två som är framför??? Killen måste ha glömt gå till skolan. :-D Men om det är 800mAh så funkar ju inte det säger han. Ladda med 40C, då går batteriet sönder. Nä... =) Den där filmen är inget för nybörjare. Sorry, måsta bara säga till.

Var till Clas Ohlson och där såg jag ett kassaskåp, perfekt ställe att förvara våra lipo ackar tänkte jag.

Turnigy nya nano-tech A-SPEC

3S 65~130C Lipo Pack
Image
* The nano-core technology in lithium ion batteries is the application of nanometer conductive additives.
1) The nanometer conductive additives form ultra strong electron-conducting networks in the electrodes which can increase electronic conductivity.
2) These additives create a super strong ability for imbibition in the carrier liquid to supply more ion channels. This improves the ability of ion transmission and ion diffusion.
Through improving electronic conductivity and ion transmission, the impedance is reduced and the polarization of high rate discharge decreases greatly.
Advantages over traditional Lipo batteries.
Power density reaches 7.5 kw/kg.
Less Voltage sag during high rate discharge, giving more power under load.
Internal impedance can reach as low as 1.2mO compared to that of 3mO of a standard Lipoly.
Greater thermal control, pack usually doesn't exceed 60degC
Thickness swelling during heavy load doesn't exceed 5%, compared to 15% of a normal Lipoly during heavy load.
Higher capacity during heavy discharge. More than 90% at 100% C rate.
Fast charge capable, up to 15C on some batteries.
Longer Cycle Life, almost double that of standard lipoly technology.

Varför sätter dom XT60-kontakter (klarar max 660A) på en sådan ack?
