車用 LIPO 低壓警報器幾＄
有什麼工能，定係到低電壓時只色停，還是會有轉向呢．． ??作者: killercheung 時間: 2009-7-16 17:54

LOW VOLTAGE CUT OFF SELLING IN HOBBY HOBBY FOR 90HKD
IT WILL CUT OFF THE INCOME OF BATTERY WHEN THE VOLTAGE IS LOW作者: hk_sdu 時間: 2009-7-16 19:04 本帖最後由 hk_sdu 於 2009-7-16 19:06 編輯
i have a lipo cut off, KWS selling at $35. Full battery with 3 green light on, then 2 light on, if it is lower than 3.7V. The red light is on and with beep beep sound (power source will not cut off), u will not hear if the car is far. But i found it useless ....
Better buy $50 one with voltage display and just stop to play at around 3.8 volt if u want to treat your lipo better.
Or use lipo cut off from your ESC build in
some expert c-hing, just play for 5 mins and stop, of course they know the battery will stay on or above 3.8v.作者: tomatchinhk 時間: 2009-7-16 19:08
3.8V 會吾會太早cut 呢，還是cut 左之后番來度到的電壓呢．． ??作者: hk_sdu 時間: 2009-7-16 19:59
up to u, some people play until 3.3v.
I also think 3.8v is too early, from my experience, in a 400mah lipo, if i stop at 3.8v. Next recharge to battery full will push in 2500mah. It means the battery still have "around" 1500mah not used.
No need to be too precise on the voltage, just stop it around 3.3-3.7 volt la. But when u feel the car power become "soft", it is quite low already and u should stop immediately.作者: hei26 時間: 2009-7-16 21:02
係kws買 "必必機" $30大元

我初初都有用, 但發覺經常聽唔到bb 聲, 所以無用到.......
而家我通常玩10分鐘到就收車...作者: ledtech 時間: 2009-7-17 11:06
我見到"好吟"有只自動CUT電嘅保護器,價格都係開兩隻BB機咁上下,不過好似沒得自己SET到3.7咁高,最多只能到3.1,唔係好敢用..作者: tomatchinhk 時間: 2009-7-17 14:18
