Cellpro 10XP Charger


Cellpro 10XP Multi-Chemistry Charger

Cellpro 10XP, 15A, 600W Multi-Chemistry Charger

Part Number: LC10S15ADC-MC

Built on the original Cellpro 10s charger technology and feature set, the ALL NEW Cellpro 10XP is designed to provide a whopping 15A max current output, and 600W of power (rated @30V DC input when charging a 10s Li battery) - all without increasing the size from the original product, and available at an extremely competitive price. At right around $.25 per watt, you will be hard-pressed to find a safer, faster, more-complete solution to meet your charging needs in the 600W class. Supporting manual charge currents up to 15A or AUTO Charge rates (1.0C, 2.0C, and 3.0C), the CP10XP is capable of safely charging one or two lithium battery packs. Add to this new features like Multi-Chemistry support (the CP10XP can charge Li, A123 (LiFePO4), NiCd, NiMH, and Pb battery types), Auto charge or discharge to storage levels (Li only), 10 user-configurable presets, free Charge Control Software (CCS), and you really start to get an idea of how much value is packed into this U.S.-designed and supported charger.

As a lithium battery charger, the CP10XP still maintains the key aspects of the original 10s in that it is literally a plug and play device. After connecting the batteries to the charger, charging commences with the press of a button. The charger will always remember the last-used preset. But leave it up to FMA Direct to come up with clever, intuitive ways to support multiple chemistries. Out-of-the-box, the Cellpro 10XP is ready to handle virtually any type of battery available. Chemistries are assigned to user presets. Just select a preset, connect the battery, and press the START button. Chemistries, cell count, and current can also be changed at the charger "on the fly". If using the free CCS (requires FUIM2 or FUIM3 PC USB interface), full access to available preset parameters are easily adjustable including preset names, selection for multiple canned fuel tables (to improve the accuracy of AUTO charge mode for your battery types), an more!

Because it is a Cellpro, it is designed to be safe first and foremost. It is virtually impossible to damage batteries with the Cellpro 10XP charger. It will not let you make a mistake. It must see all the cells in a Lithium pack and the sum of the cell voltages must equal the total pack voltage. It is ideal for charging one or two LiPo, LiIon, or A123 type batteries. When two packs are connected to the 10XP, it automatically interconnects them in series internally inside of the charger. It essentially "sees" all the individual cells as one pack of cells. It can handle 1s-5s on either or both balance charge ports, or it can handle up to a 10s battery pack using both ports. To achieve the full 15A max output current, connect both the balance connectors and the main leads from the pack(s) to the banana jacks.* While the Cellpro 10XP can handle charging two packs of different capacities or charge states, it is mainly intended to support 2 pack charging when the packs are the same or similar capacity and state of charge, such as 2 x 4s packs which are wired together in series or parallel during operation in an electric aircraft.

The Cellpro 10XP charger supports the direct connection of all Cellpro Revolectrix battery packs. Certain Cellpro battery packs may require the use of the Cellpro 6 pin-to-5 pin adapter (sold separately). In addition, FMA currently sells 4s adapters separately to interface with various manufacturer's battery packs up to 4s configurations. If you own a Cellpro 4s, Cellpro GOLD, or Cellpro Multi4 charger, you may have the adapters you need already. These adapters may be used with the new CP10XP charger for packs up to 4s by connecting through the Cellpro 6 pin-to-5 pin adapters. FMA also offers Cellpro 10s adapters for other manufacturer's 2s to 6s packs for use with the Cellpro 10XP directly. Two adapters are required to charge two packs using the Cellpro 10XP charger. If you already own Cellpro 10s adapters, these work directly with the Cellpro 10XP as well. It is recommended that you download and read the available User's Guide to determine your precise requirements. Click here to view the Adapters page. A customer may also adapt to his larger battery packs (over 6s) by installing the 6 pin Cellpro balancing connectors (CPBP6P-10) or a combination of the 5 pin Cellpro balancing connector (CPBP7) and the CPBP6P-10 to his battery packs directly. All current and future Cellpro Revolectrix branded battery packs will adhere to the following conventions for the above connectors. We recommend that customers adhere to the standards we have defined when re-wiring battery packs using the Cellpro battery pigtails.

2 CPBP6P-10

Last, but not least, the new Cellpro 10XP also supports XH MODE wiring. This feature originally became available in the Cellpro PowerLab 8 Battery Workstation. By default, the CP10XP is set up to work on the original FMA wiring standard. But if the wiring mode is switched to XH MODE, the charger will work with batteries including the ever-popular JST XH or EH balance connectors and wiring scheme. By switching the CP10XP over to XH MODE, you can easily interconnect the charger to your favorite standard or parallel adapters. This involves retrofitting (replacing) the JST XH/EH balance wire pigtail coming from the standard or parallel adapter with the 6 pin Cellpro battery pigtails (CPBP6P-10) described above. XH MODE is also covered extensively in the available user's guide.

* Note - the Cellpro 10XP charger no longer supports balance-wire-only charging and; therefore, no longer requires the "plug blocker" that came with the original Cellpro 10s charger.
