A123 Battery Cells For Your Radio Control Electric model airplanes have been in existence for roughly 30 years. A massive problem in the past was battery energy density. Quite simply, they just considered an excessive amount of for the quantity of juice you can get from them. This case has improved dramatically recently using the creation of Li-Poly cells, however a battery power for any bigger model can certainly cost 100's of dollars. The arrival of electrical cars, like the Toyota Prius has spurred a whole lot of research into new battery technologies. In the following paragraphs, I'll describe an alternative choice to LiPoly batteries that provides intriguing options. A123 Systems produces Lithium-Ion Nanophosphate cells. These cells possess a nominal current of three.3 volts and may withstand continuous discharge rates of 30C. They may be securely discharged lower to two. volts. The current remains fairly constant with the discharge cycle, however they will have a clear, crisp drop-off in the finish. Expect 300 cycles before you decide to notice any decrease in capacity while at 1,000 cycles you will have 75% from the original capacity. They're safe. Overcharging or higher discharging won't cause a surge and can haven't much impact on the existence from the battery. Balancing cells when they're billed continues to be advisable, although not absolutely needed. They may be billed soon after use within fifteen minutes. ( li polymer battery pack ) Cells can be found in two sizes. The initial M1 cell includes a capacity of two.3 Ah and weighs 70 grams (2.47 oz). A more recent, smaller sized size holds 1.1 Ah and weighs 40 grams (1.41 oz).
The main source for A123 M1 cells continues to be DeWalt 36-volt portable power-tool battery power. Each pack contains 10cells. I got myself a couple of these for $100 each through Ebay. The costs have the symptoms of increased lately towards the $120$130 range. Single cells may also be purchased online for $15 from the growing number of vendors. You'll find two smaller sized cells inside a Black & Decker VPX battery power which costs about $15. The smaller sized cells may also be had for $12.50 each. There are lots of Li-Poly chargers that support or could be modified to aid the charging of those A123 cells. Due to the sharp current drop-off when discharged, you're most likely best utilizing a timer whenever you fly. Or else you need your ESC to seal from the motor when 2. volts per cell is arrived at. Main point here? These cells provide you with 70% the power density of Li-Polys for around 45% from the cost. For a lot of us, that's a good trade-off. They're very safe and could be billed in fifteen minutes. Should you finish up buying half as numerous battery power due to the shorter charge time, they become a far greater value.
