DIY Li-Polymer Battery Pack

最近我在鴨寮街電子五金舖買了兩粒samsung製鋰電，3.6V, 2400mAH，在家中將它們串聯一起，放在18仔大腳車上使用，發現性能不錯，加速及極速址比以往用的1400mAH電為高，並且使用時間多了差不多一倍，值得推薦。

六粒1400mAH共重128g，而兩粒2400mAH只有92g，故能有較佳表現。
請參考圖片

Seems so good !   3.6V or 3.7V each pack ? how much for 1 pack ah ? did you use the balance charger ? seem you did not have a balance plug in the pack.

係咪2A size 黎ga?

無咁爆, Li-Ion 個設計唔係放大電流使用 !

係咪2A size ??
係邊間買??
thx....

應該唔係 2A, 鋰電 SIZE 好似用 17650, 18640, 來分的. = 17 MM X 65 MM, OR 18 X 64 MM 咁解 ,  有錯請指正.

呢種電我早三個月前以買黎用去（Superfire）電筒，

但一著無幾奈就燒左七粒LED，真係氣都頂.......！

跟著我又諗.......如果放落18仔咪好掂..........！夠曬輕.....！正....！

（呢個Topic好就係好，但這裹吾係18仔討論區喎，小心......好快有人黎Ｘ你地呵........！）

即係以前的（相機電）size囉.....！（記著吾好落相機呀......即燒呀.....！）

相機電 ? cr123 ? cr123 是 3v 的, 不可以充電的, 但最近好似有 d 可以充電的 cr123 推出左.
若是原裝用 cr123 = 3v, 但你放支 3.7v 的落去用, 真係好可能會燒的啊 !! 我都試過
要留意使用電壓呢.

The size of battery is larger than 2A. The diameter is a little bit larger than 1.2V 1400mAH butter shorter. The prize is $55.00. As you can see, two batteries connected in series can just fit the battery holder in 18size mini bit foot.

I do have balance charger, but I cannot find the balance plugs for it. So I have tried to charge them individually by IMAX BC5 and charge them together by much more. If I could find a balance plug, it will try to charge again.

there are 3A and 2A li-ion batteries out there, costs ~$20 each

Voltage of Li-ion is 3.7V / pc, not as rechargeable AA 1.2V. be carefull not to burn your EX-10

見人地多數 用 3粒做發射電 , 3 x 3.7 = 11.1v, 但亦見有d 版友不讚成的. ........

點解唔讚成ge?唔耐用?

我話太輕既意思可以搞到支控個重心去左個槍頭到

當 11.1v 充滿電時, 可能會傷支控羅.....   
支控既平衡都係有問題 既 .....

2200mah, 25C 可以放55A~66A 電流，唔知Ni-MH ge電流有幾高呢
