Quick Overview

50W 4S Balance Charger
The Cellpro Multi4 charger directly supports all Cellpro Revolectrix battery packs. FMA sells adapters separately to interface with various manufacturer's batteries. Click here to view the Adapters page. Click here to view a pictorial diagram of Cellpro battery standard wiring conventions.

Built on the success of the Cellpro 4s and Cellpro 10s chargers, the Cellpro Multi4 represents the next step forward in charging technology. So much more than just another charger, of course the Multi4 is based on FMA's time-proven, reliable hardware designs and safety algorithms, but sports a new microcontroller that is 4 times as powerful as the one used in the Cellpro 4s. But the true power of the charger stems from totally new firmware. We started with a clean sheet of paper and a lot of "thinking outside the box". The extensive list of features and capabilities are rivaled only by the goal to provide the ultimate in flexibility and utility. Out of the box, the Multi4 will run circles around the competition in terms of simple, yet powerful set up and operation. But if you are the type of person who likes a more custom solution, look no further. The charger, in combination with the Charge Control Software will offer virtually unlimited access to charging parameters.

Why did we take this path? Over time, we have received many requests from customers about specific features they would like to see in our chargers. Sometimes we can add these features. Sometimes we do not have enough memory left in the microcontroller to make it happen. Sometimes making a change that one customer wants to see is something other customers do not want changed. But no matter what, the changes require countless hours of meticulous firmware updates and debugging before new firmware updates can be made available.

So, a more powerful microcontroller in combination with the new Open Architecture presets philosophy enables us to make everybody happy, in an efficient and superior way. Adding a new feature, tweaking parameters, fixing problems is as simple as correcting or creating new presets.

Let's look at a couple of examples. Customer John wants his charger to balance A123 batteries at 100 mA as opposed to 200mA. This is a major decision for any charger manufacturer. Do we update our firmware to change the balance current? Will others like the change? Do we add a capability within the user interface so that John can set it the way he likes it without affecting other users? Do we have enough memory to affect the change? If you read about how FMA or any other manufacturer handles these things, it is usually a pretty inefficient process. The results often please some customers while others complain.

Enter Open Architecture presets. Changing the balance current, or the type of balancing, or how far along in the charge process the balancing begins is all adjustable now. Just go to the preset you wish to alter in the free Charge Control Software (CCS), find the parameter you want to adjust, and you're done. Now you have a completely customized preset for your specific battery type, situation, or application. Even if you are not the type of customer who wants to dabble in technical matters such as these, you will still benefit from Open Architecture presets. Why? Because first and foremost, FMA is introducing this concept to make it faster and more efficient for us to support the vast myriad of unique requests that we receive on a daily basis. Even if you do not wish to alter charge parameters yourself, you will benefit by gaining access to presets created by experienced technicians. Restoring presets in the CCS is as simple as opening a word processing document on your P.C.

How about some more examples? You want to turn off cold weather mode, set it to a different temperature, or alter the charge voltage reduction level? Simply alter preset parameters. You want an A123 only charger? Easy; copy a single A123 preset to all 25 banks of your charger. Alter the settings of presets individually. Save them out one at a time to your PC or just backup all 25. Got a buddy who wants your settings? Email him the presets backup file. Once he opens the file and uploads them to the charger, he's got what you got.

Here's possibly the most important part of all. Don't spend countless hours trying to interpret cryptic information presented to you on a 2 line LCD. Yes, of course you can make basic settings at the charger. But the most efficient way to make detailed and complex changes to charge parameters is on the PC where you have a gigantic screen, a keyboard, and a mouse. Make the changes to your presets at home. Call them up and use them at the field. Fly at the field, don't worry about setting up your charger there. You're likely to make mistakes.

To unleash the full potential of the Multi4, FMA recommends the FUIM3, 2 way P.C. interface and the free Multi4 Charge Control Software.
