** Please check bullet number 8 in the section titled “Major Features” below for a detailed description of Regenerative Discharge

PowerLab 8 Feature Set:

Major Features:
• Selectable charge rates range 10mA to 30A
• Continuous maximum output power rating, 1008W @ +24VDC input voltage, 516W @ +12VDC input voltage
• Using +24VDC to +32VDC input, 1008W output will deliver full current rating (30A) over the full range of output voltage up to 33.6V
• Smart power management allows customer to select between programmable input power sources. Using the Charge Control Software (CCS), choose from several templates to get you in the ballpark, then fine tune the settings. Available settings include power supply input current limit, input low voltage limit, regenerative discharge rate and voltage limit. PowerLab 8 stores 1 set-up for Power Supply and 1 set-up for Battery and asks for verification one time on start-up
• PowerLab 8 supports charging through node wires only (automatic current limiting to 3A maximum) or node wires in combination with discharge wires (charge rate support up to 30A max)
• Initiate charge, discharge, monitor, and multiple cycles at the PL8 or via remote control from the CCS. Graph all major operations when using CCS.
• Open Architecture presets allow for customization of any User Preset including show/hide presets on unit, preset name editing, up to 100 parameters control how presets are displayed and charging/discharge/cycling parameters associated with particular batteries and/or charging strategies. Unit includes 25 user preset banks pre-loaded for most major battery type/chemistries, plus 50 library presets.
• Environmentally friendly, industry first, regenerative discharge capability of up to 1000w. Unlike traditional methods of discharge, which deplete the output battery’s energy in the form of heat across a transistor, regenerative discharge takes most of that energy and puts it back into the input battery. In other words, when you discharge your LiPo for storage, you will be re-charging your Lead Acid input battery. The total amount of power that you can achieve is limited only by the amount of current that your input battery can accept, or 1000W, whichever is lower.
• PowerLab 8 is also equipped with a traditional, 100W internal discharge capability which is non-regenerative.
• Twin cooling fans
• Massive over-sized internal heat sink
• 10AWG silicon input power cable and heavy-duty, removable plier clips
• Massive sendust core toroid capable of 50A continuous input current requirement for maximum output specifications

Other Features:
• Supports native Cellpro batteries automatically
• Adapters available for all popular R/C battery brands
• 2 line, 16 character backlit LCD
• Available opto-isolated PC interface and free Charge Control Software (CCS)
• Intuitive 4 button user interface
• Sleek and attractive high-impact ABS enclosure for maximum airflow efficiency
• Sturdy Aluminum top panel with reliable, recessed tactile buttons
• Quick “preset over-ride access” to common charging parameters like setting charge and discharge current and operational modes of charge/discharge/monitor/cycle(s)
• Additional advanced options menu for adjusting in-depth charging parameters and global options at the unit
• GUI PC software (CCS) allows access to 25 User Presets and 50 Library Presets stored in the unit or available in unlimited number on the P.C.
• Free and reliable firmware updates for the life of the product using the CCS
• Automatic Low voltage restore for recovering damaged or over-discharged packs
• Programmable options allow speaker ON/OFF or volume, LCD contrast, customized welcome screen, and much more
• Cold weather mode reduces end-charge voltage; parameters adjustable by customer including ON/OFF, end-charge voltage offset reduction, and temperature
• Multiple product cases can be interlocked
• Future provisions for master/slave mode whereby one PowerLab 8 master can control one or more slaves, send over preset information, control all aspects of charging and balancing. This feature is perfect for charging multiple packs of same chemistry and capacity using multiple devices such as split packs connected in series during operation all at unbelievable rates.
• Auto charge mode available utilizing advanced fuel gauging technology
• Customizable fuel table lookup values based on presets. Fuel tables can be created using a Fuel Table Wizard in the CCS and applied to individual battery brands by presets for improved accuracy
• COMING SOON! Industry’s first Smart Parallel adapters available to maximize available power potential. These items will be peripheral products, available separately, not included as a part of the actual PowerLab 8 unit.

Please note: all specifications and features listed above subject to change prior to delivery

几个亮点：
• 充电功率上 KW。意味着对 8S Lipo 也能 30A 充电。
• 放电功率上 KW，而且很巧妙的解决了发热问题：用放出的电反过来给电源（例如大型铅电池）充电，所谓 regenerative charge.
• 可自行设定内部DC-DC 的工作频率，以在不同输入/负载的状况下得到最高的转换效率。
• 可直接通过平衡线充电（3A以下），或者通过主线充电（max.30A）
• 电压，电流在出厂前经过高精度校准。电压精度 6mV，分辨率78uV.
• Max输入电压高达 32V.
• 全面测量/记录电池参数，精确测定每一片的内阻.....

看LZ的帖是种享受，顶！难道还是沙发？

Environmentally friendly, industry first, regenerative discharge capability of up to 1000w.

这个确实是亮点，另外78uV的分辨率也是看得我一震啊。

最近看上了CELLPRO 10S,不知道Himalaya兄对这个牌子的充电器了解吗,,只是听说平衡精度比较高,似乎性价比不错,,,

这个是强悍！！！！米也多吧？？？？

我也被震到了，但估计最震撼的是价格，说出来震震吧。

回楼上某兄，充电输出电压和输入电压已经基本无关了，反正现在充电器都是dc-dc的设计思路，可以升压的。但输入电压会影响效率，and输入电流

是滴。
最大输出功率跟输入电压相关： 516W@12V，1008W@24V。

好吓人。。。。。看来50C的锂电是骗人的。。。。

我也被震到了，但估计最震撼的是价格，说出来震震吧。

价格据透露在250~300美刀之间，相对性能而言，还不算太夸张。
