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

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. Click here to view a pictorial diagram of Cellpro battery standard wiring conventions corresponding to the following summary:

Number of Cells


1 CPBP6P-10

1 CPBP7 and 1 CPBP6P-10

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.

Looks great-it's about time FMA decided to kick some cheap, Chinese arse!

#3 BMW318TI Jul 28, 2011 10:37 AM

OMG there goes my money.
I have just bought Cellpro 10S, but this one looks soooooo good!
I will buy it!

CP10XP Auto 3C of 3S 2200 40C(?)
3 Attachment(s)
This LiPoly rated 40C but is really more like a true 25-30C however as I help develop the Fuel Tables for this charger I wanted to see how it behaved under such circustances. Looks good to me.:)

Added Auto 3C charge of Billowy 60C using 50C fuel table .

Added 15A manual charge using 12V power supply

FYI Auto C rate charging is limited to a max. of 6 amps.

#5 Gregor99 Jul 28, 2011 02:23 PM

Auto mode looks much improved. But are we back to using a single fuel table for all packs? Does that provide reliable results?

As for the charger announcement, I'm very happy to see FMA working on filling the sub-1000 watt charger catagory. But I feel the specs could result in some customer sat issues when they discover that very few common charging configurations will come close to the 645 watt rating. I would much rather seen either increasing the output current to 20 amps, or increasing the cell count to 12 and keeping a lower current rating. This charger will be best suited for modelers using 4s, 5s, 8s or 10s. Modelers with 3s, 6s, and 12s would do much better to stick to the Powerlab8.

Options available are for 15,25,40 and 50C and yes Fuel Tables are more accurate and Auto C works much better on ones I have tried it on.

FYI The POWERLAB8 was used to generate fuel tables and I ran them for 25-65C Lipolys and FMA's Engineer took my Fuel Tables and other placed them in a spread sheet and came up with the ones now in the CP10XP. Here is hoping they suit the masses as I have around 80 hours in the ones I ran.

No perfect charger for everyone. This charger will satisfy the needs of many. Electrics continue to get larger and more powerful however many still use 2-4S of less than 3500 mAh Lipolys and this charger even on a 12V power source will charge either singles or pairs of sizes that many use.

Thank you for that. One reason I've not created the fuel tables is the time investment, so I appreciate that work went into helping every Cellpro10xp customer.

As for no perfect charger, the inventible iComparison to one particually similarly priced charger may produce unhappy customers that thought they were getting almost twice the wattage. But it turns out they ended up with even less usable wattage than the other charger.

While I base my purchase decisions on far more than just the "max number", I know the cannot be said for the majority of modelers. Time will tell and hopefully this model will make big spash in that sub 1000 watt market.

#8 everydayflyer Jul 28, 2011 03:28 PM

Fact is I only do Fuel Tables at FMA's request as I have no use for them myself. I know that 3.7 is (empty)as low as I like to fly to,that 3.8 is storage,4.1 is 90%.4.15 is 95% and 4.2 is full or atleast close enough in my book..

I only use Auto C rate when I am charging a wide assortment of LiPoly at the field and do not want to end up charging a 500 or 1300 mAh one at 10 to 20Amps by mistake.

Auto 3C took 25 and 30 minutes while 5.7C (15A) took 12 minutes. If I used Faster Charge instead of Accurate Balance the 15A charge would likely been closer to 10 minutes and that is my normal turn around time when I fly.

I'd like to know if the two charger outputs can be controlled individually and used to concurrently charge 2 different chemistries.

ie, can i charge a Lipo pack on port 1 while i charge a NiXx receiver/ignition pack on port 2?

No, they are not independent outputs. In fact, on the original CellPro 10S it was advised that if you were charging two packs of greatly differing capacity you could stop the charger when the small pack was full then restart to finish the bigger pack. Think of it as a built-in mechanism to connect packs in series for charging.

It's possible to use the CP 10XP firmware on the old CP 10S?

I don't know for certain, but I'm guessing they use a different micro-controller in the 10XP and you couldn't even begin to fit the 10XP firmware into the 10S.

Sorry, the CP10XP is a lot more than just a firmware update to the original 10s. If you tried to load the 10XP firmware into the 10s, it wouldn't let you because it's an entirely different product code.

#14 BMW318TI Jul 31, 2011 03:33 AM

Okay thanks!
Because I don't use A123, Life etc batteries.
I am just use lipo (and NIMH) batteries on the CP 10S.
Will be there a firmware update for the CP 10S without A123, life batteries charging features.
So the new charger features for NIMH and PB batteries will fit in existing micro processor?

To quote Tim from a recent thread "No additional features will be added to the 10s". The technical reason why not is that the micro-controller is full and there is no room features to be added to the firmware. The business reason why not is that it is a mature and reliable product and there would be little to no return on the time and money it would take to add new features even if it were technically possible.
