叉機set5A去充電, 但係顯示係得3A去叉電?

點解叉機set5A去充電, 但係叉機顯示係得3A去叉電? 係叉機問題定係鋰電問題 ? 唔該師兄~

師兄
你用那部差機?

你排電係仲有電底??
所以會降低叉入電壓!!

師兄你叉3S電？

明白! 係呀我之前用左storage mode, 每cell仲有電 3.80v~ 係咪應該每cell放電到3.0v之後至叉電 ?

我叉6S電

做乜放到3.0至叉

試過一次discharge放到3.0至叉, 叉滿左d力水又好似特別爆d.

What is the output power(W) of your charger?

叉機話出到5A係響某個輸出電壓以下，你差6S電個電壓超過果個數，所以個電流要減小。

Charge power 350W, max 25A.

Your charger output is file.
6s 5A consumes about 3.7v x 6 x 5A = 111W.
When reaching 4.2V, it only consumes about 126W.
If your power supply is sufficient and your lipo pack is not damaged, then it seems your lipo pack has reached 4.2V per cell and your charger is lowering the charging current.

Are you sure this is the charger output?  Because it sounds like an output rating of a power supply to me. Some chargers cannot utilze all power as they are not capable to charge the battery at this rate so they will just lower the charging current just like your situation.

For example, if you connect a 100w charger to a 350w power supply, the charging power of your system will be only around 100W

So what charger are you using?

charger係Vistapower AP625, power supply係12v 400w.

咁睇落差機同火牛都應該夠哂數WOR, 你有冇試差其他電有冇相同既情況出現?
