咁樣 cycle d 電唔知對唔對

用 1C charge > 休息 > 1C discharge > 休息 > 1C charge
cycle 兩次夠唔夠? 咁樣搞一搞都成十幾個鐘

例如 800mah 全程用 0.8A charge & discharge

講d技術性小小o既野就無人回啦

唔係個個對d電池都要求咁高.
我冇放電嘅習慣, 又只係用gp义機, 速度都冇咩問題.

無錯, 問過下 D c 兄, 佢地都話要求唔駛咁高, 攪到好似仲誇過玩 10 仔咁, 又放電, 又 match 電, 又用幾多 a 去差, 嘥鬼氣, 差 3A 啫, 唔駛咁誇張, 分別又唔會太大, 用 GP 15 分鐘嗰部去差, 爆到 pk, 有 D 人話咁差 D 電會快 D 死, 唉......死咗咪買過囉, 都係講緊 $50 排

記得起初都係咁諗, 用GP叉機, 但d電好快打柴,
之後玩耐左買部靚d既叉機, 研究下點去叉電, keep電放電等等,
d電真係會發揮得好d, 好唔同ga...
可能Ching你應該好有米, 但咁貴一排電, 當然想用盡佢...

不過講到match電及cycle電真係無咩研究, 一個字.."懶"

搞cycle正路做10次左右, 聽某d賣叉電既朋友講, 做cycle一般用低電流0.2c充放, 所以會搞成個星期 (但我自己用開1c....都ok囉)
800mah, 1c ===> 0.8 x 1 = 0.8A電流
做曬10次最後對電壓, 再跟據最後既 內阻 同 電壓 match

兩粒同一個時期, 內阻同電壓都相約既電放埋一用性能的確會好d (嚴格講)

係你睇唔起d車仔姐
d電玩左10次左右就match下佢，每排都好力左
十五分鐘差機用成3A差入去，相等於3點幾C, 有常識都知唔掂啦

sorry, 你誤會喇, 我完全無睇唔起 D mini, 相反, 我仲好鍾意, 我自己都有成 3 部, 2 部 AWD 加 1 部 F1, 只不過我覺得一排電先講緊 $50, 我玩咗咁耐, 平均一排電 over 半年以上先死一至兩粒, 都好抵, 咪唔駛咁麻煩去攪 D 電囉, 絕無其他意思........

我無理咁多
3A電我多數用2~3A差,上下夾風扇heatsink
D就死/唔爆ge電,最大試過用4A,cyc&打peak
只要set 好溫度唔好比佢heat就得

平時cyc用部差機program 3差10放,delta / peak set 高D

keep電就用1A差,delta / peak set 最底

記住玩車就係燒錢
要點燒&燒得有幾豪氣就睇你自己

計埋計埋弟以前係bjs燒左大約3盒AAA 電,
唔得果D比晒細家人用gameboy/remote/md/電筒/......etc
換左幾年有D出埋汁都未replace晒



上面有ching 講用 gp 15mins, 果部真係好野, 加多2隻風扇對流吹仲正

另外有時去做人腦精選D時都會CYC佢幾次先

I don't think GP 15 mins version is OK for nimh cells. I support using only 1 hr version.

觀點唔同先有得討論
我話15好野因為快D有得玩+我認為玩車=燒錢
ching你support 1 hr 可能咁玩D電"com"用電

ching 都講下D優點比大家身參考下吧

although i am asking questions about cycling NiMH batteries, i am using GP1hr too actually =p

i even have three of them, haha ~

同意, 我都有部 GP Powerbank (15 minutes), D 電好快瓜柴...

而家係用 Team Orion 差機, DIY 差電架, 用 1.5A-2A 慢慢差.

Buy a few 1 hr version and you can keep running.

One advantage of using GP 1 hr version is every cell is individually charged. Because the charger comes with temperature sensor, no cell will be overcharged in theory, which is better protecting the cells than using very advanced charger to charge 4 cells in series, during which the cell which has the lowest internal resistance dies first as it is overcharged every time while the other 3 cells are still drawing energy, cheating the charger to go on charging. (see if you understand)

Question: how many A does the 1 hr version used to charge the batteries?

I think it is about 0.8 A. If it really takes an hour to charge a 750 mah cell, the charging current is exactly 750mah. If it takes only 30 mins to finish charging a 750 mah cell, the charging current is 750 divided by 0.5 hr, which is 1.5 A. (The formular:The capacity of the cell to be divided by the time it takes to finish charging it.)
