I have a ip lipo 4000, 25c for about 3 months, last night before I play, I read S1 has zero volt! S2 has 7.78V!!!! Any brother has experience about this? Most importantly, can this battery be fixed or should I dispose it?
Yes, it does not make sense. but mini lipo reader measure other lipos reading are normal.... The balance charger cannot charge this battery either...作者: Noir.KAZE 時間: 2009-6-26 08:09
咁如果其他電係差到冇問題,就有d奇怪
可能舊電死到個讀數都錯埋........但係唔知有冇咁既可能作者: mlee 時間: 2009-6-26 08:25 6#Noir.KAZE

You can check any disconection or broken of wiring or at the solder joins using a voltmeter. I have one disconnected at the battery side.作者: Andrew168 時間: 2009-6-26 10:20
我之前都有 pack 2 cell ip 4000電又係突然間有 1 cell 0 voltage,
分開獨立 check 都係 1 cell 0 voltage, 另外果 cell 正常作者: edmondhk 時間: 2009-6-26 10:53
可能有一條balance線甩左
因為佢係用totel voltage減其中1cell既voltage計第2cell既
用就唔係用唔到,但係行唔到balance差law作者: cottonchu 時間: 2009-7-2 23:04
b4 charge: 1 cell = 3.7V, 2 cell = 7.4V, 3 cell=11.1V作者: mlee 時間: 2009-7-3 00:55
I disassumbled the battery and found that one of the balancing wire were loosen. Both red and black are good=> that is why total voltage is showing 7.7V. The blue wire was detached from the battery, the battery is back in action after some soldering. The only thing to do is to glue to casing back together.
