This is the new powerful battery which have no danger of explosion like the Lipo ones:
http://www.aircraft-world.com/shopexd.asp?id=5041 They are 3V batteries. Is it possible to use them directly as a 6V receiver battery pack ? |

High capacity Fast charging High discharge current 3V per cell Long life Safe Light weight Seems very goooood !! Lets get some and test. |

Seen at Lomcovak site already. Yes it is powerful and some pylon flyers in Hong Kong have already used it. Seems ok! By the way, weight for a 6~6.6V 2 cells pack is aroound 140g+, our current 4 cells RXbattery is 100~120g. |

實亭呢D係咩野電黎架 ﹖化學成份係也 ﹖ 仲有我想問下最近開始流行話唔會走電果種 NiMH 電到底係咪可以用普通 NiMH 差機差既呢 ﹖ 會唔會爆炸既呢 ﹖ |

仲未知電壓太底点樣保護佢,底過2.9v-2.8v,會唔會整死D電,如果一般鋰电用底過2.6,已經瓜咗!!接收機可能底到4.2V-4.5V先至失控,所以鋰电用於接收又冇WARNING 系統,其實好危險!!电壓在2.8V以下,跌得非常快,我一定唔會用!!睇定D好D!!!!!! |

Dear YC, The Sanyo's Enneloop Nimh works great. I have been using it for 4 months. Just use normal Nimh charging equipment. They are a bit lighter than the old Nimh, say 10g for a 4 cells AA RX pack. |

我就唔等啦! 呢隻電我巳經留意左幾個月,只係未?到方便買既地方。(極之睇好呢件產品,所以重??有關生產商既資料。可惜係美股,否則就已經入重貨!) 昨晚上 Aircraft-world 睇到廣告就第一時間同大家講。同時 order 左兩件返黎試。 用得好既話,會將我全線 F3F 機隊換電 : )
用黎做接收,我打算將底點定係 6V。咁就極之安全啦 |

5 分鐘差滿﹐100C pulse, 35C continuous. 長壽安全﹐勁 ﹗ 完美程度近乎虛假﹐呢D電實庭有無缺點 ﹖ |

仲有想問下點差﹐佢話 3A to 3.6V CCCV 45 min 10A to 3.6V CCCV 15 min |
