我的是 60W,圓尖咀,剛用來焊多兩粒 500mAh Sanyo AR 電池落pack電內,是「一條柱」式,直接頭尾焊,無用 connector,除了最後一粒電池外。

我搞了好耐,請問 60W 是否足夠?我辣到 pack 電好熱,電池殼外的 label 都發脹,希望無事。現在正慢差,不覺有短路問題。

60W 應該夠力,不過你銲到label都發脹就好似有問題,銲電最緊要辣雞夠熱,以最少時間加熱電池至銲錫熔解的溫度,用扁平的辣雞咀轉熱較佳,我支只係40W,不過係恆溫既,Set到400C一般電池都冇間題。係hobby lobby 有一種銲電專用的jig,睇黎唔錯,http://www.hobby-lobby.com/bataccy.htm 不過我比較喜歡用吸錫線做tab,較易銲,撞機時又可作緩衝。

Willy, 焊之前最好用砂紙擦個電池金屬片,易上錫好多,唔需要焊到個電池label發脹

Pack 電焊得好差,因為今日「科大」試,第二個 flight,在半空未到一分鐘,巳經 motor cut,半油都唔郁,降落後連 receiver 及 servos 都唔郁。

其後檢查,發覺其中一塊銅片竟與電池分離!我估我最後一 cell,就咁用兩塊銅片「凌空」焊著其正、負極當作固定,是不襟前一次降落時的震盪。似乎銅片在半空幾乎完全分開,僅連接的部分不足讓足夠電流驅動摩打(但幸好夠推動遙控),而此僅連接的部分,也在降落時震開了,以致其後無控。

一呃冷汗。
