3D 6分钟 推算是这样的2000MA*60/6=20A,算下来你的功率只有20A*30v=600W 左右,这个功率对600来说不够只是航线翻几下,3D的话起码要1200W(600暴力功率要在1800我左右)以上这样平均电流就要40A飞行时间只有3分钟了,所以我一开始就建议你A123上12S以上,这样电压上去了电流会下来,弥补一下飞行时间不够。
把手上以前收集的资料和数据找給大家参考下,用A123和锂聚电池的比较用数据说话(呵呵理论上)。
我想鬼佬这方面就做的比较好:这是抄鬼佬网站上的数据:

----------------- ----------------- ----------------- ---------- ----------
Notes:
1) Loaded voltage estimated from published discharge curves
2) Usable energy indicates runtime. Assumes max 80% discharge for lipo, max 90% discharge for A123
国产电池最多放60%(安全点吧!) A123 放电90%
鸭托垃圾4400电池放电80%=59.2(J/焦耳) A123 10S 90%放电=52.2(J/焦耳) 这样的比较自己算吧。
3) Usable current/power is based on keeping pack temperatures below 140F/60C to ensure maximum
pack lifetime (>100 cycles for lipo, >500 cycles for A123). For LiPo this typically means
staying below 75% of rated current. For A123 lab tests show that it means sticking to a
rating of 16/33/50C. If you are happy with only ~100 cycles from the A123 packs then you can
push them somewhat harder than the estimates indicate.
