-  Operating software
   The operating program in this charger is executed with mutual links and communications with every component to prevent any possible error, so it introduces the maximum safety. Especially, the charging algorithm is so multifarious that you can select the best program to suit your requirement. And BC8DP has a large LCD for showing various information including charge/discharge graphs during the process.
- Dual input power
  BC8DP employs the circuit that can be operated at AC(Alternating Current) or DC(Direct Current) input power. For AC input, the charger contains a AC-DC switching power supplier inside, which has 10A of power capacity and maximum output power of 120watts for charging. As a result, it can charge up to 22 cells of NiCd/NiMH and 8 series of Lithium batteries. When you use DC input power, the circuit power will be increased to 180watts. But there might be the limit of feeding current to a higher voltage of battery. Please refer 'Maximum circuit power chart'.
-  Individual voltage balancer for Lithium batteries inside
   BC8DP has an individual-cell-voltage balancer inside. So it does not need any balancer separately when charging Lithium batteries (LiIo/LiPo/LiFe) for individual voltage balancing.
-  Monitor the individual voltages on discharge
  BC8DP will monitor the individual voltages of the Lithium battery pack during discharge process as well as ‘FAST’ and ‘STORAGE’ mode. If the voltage of any one cell varies abnormally, the process will be stopped with the error message.
- Maximum safety
  Delta-peak sensitivity : The automatic charge termination program works on the principle of the Delta-peak voltage detection. (NiCd/NiMH)
    Auto-charge current limit : When charging NiCd or NiMH at 'AUTO' current mode, you can set the upper limit of charge current to avoid from feeding high current to the battery. This is very useful when charging the low impedance and small capacity NiMH battery in 'AUTO' mode.
   Capacity limit : The charging capacity always calculated by multiple of the charging current and time. If the charging capacity exceeds the limit the process will be terminated automatically when you set the maximum value.
   Temperature limit : The temperature of the battery on charging or discharging will be raised by its internal chemical reaction. If you set the limit of temperature the process will be expired forcibly when the limit has been reached.
   Processing time limit : You can also restrain the maximum processing time to prevent any possible defect.
-  Cyclic charging/discharging
    Perform 1 to 10 cycles of charge>discharge or discharge>charge continually for battery refreshing and balancing.
-  PC based analysis using USB communication
    For technical expert, BC8DP offers PC based program can analysis the characteristic of the battery via USB port. It shows a graph of voltage, current, capacity and temperature curves. It also shows the individual voltage of each cell in the Lithium battery pack.

Accessories
EAC110	Temperature sensor cable	Standard
EAC117	4mm gold banana plug with silicon cable and alligator clips	Standard
EAC300	Program kit for PC (CD + USB cable)	Standard
EAC13X	Balance adaptor board for Lixx	Optional

简单浏览了下，发现特点：
110-220V交流和12-18V直流双输入：在交流输入下最大功率120W，直流输入下最大功率180W（比BC8DX的单路160W有提高）；
相比BC8DX，Ni电增加了一种放电模式：CV模式，能更彻底的对Ni电进行放电；
增加电池监控，链接电池即可显示各项参数：总电压，每个Cell电压，电池温度（外接探头温度）
改进为Jog-Dial转盘输入；
最大充电电流10A：相比BC8DX的9A有一点点提高；
其他大部分技术细节同双路输出的BC8DX；

个人认为充电电流还可进一步提高，但是实用意义也不是很大，因为功率180W的情况下，只能使最多4S的Li电充电电流达到10A，5S已经无法达到10A了，功率到250W以上再提高最大充电电流比较有意义些，相信各家还会不断有更强大更变态的产品推出……

同意。

在 5C充电LiPo 全面替代旧款的今天，功率和电流意味着一切。
这个产品的定位看上去有点中庸，既不是给高端玩家用的纯 DC输入的大功率大电流型，也不是字符液晶+AC输入的入门款，不高不低。

PS：H记0610的时代（最高电流10A）BC8DX 是 9A，现在 H记有了0720，0615duo，Bantam 出了 10A，看出点什么么？ 9A能出，10A就出不来 ？？  哈哈，瞎猜......
