I wonder if you could speak about the differences between Powerflite and Duralite batteries. Of particular interest is the built in charge regulator that Duralite is now putting into their packs, is it an advantage? Does Powerflite have a similar system built into it's charging system. I am building a 33% extra and I am deffinetly looking seriously at using lithium batteries. I need as much information as I can get to make the correct decision for a successful project. As you said above I don't want you to "Flame" the competion. I just want an objective comparison. Powerflites seem quite a bit more expensive than the Duralites. I assume there must be a reason.
Thanks [/QUOTE]
Thank you for your question.
First off, let's touch VERY briefly on price. We have just gone through a price change that has not gone public at this point. I suggest you check here or on our website for the new prices to be released soon. An example would be for your 33% plane, I would suggest one of our PowerfLite Professional Sets. The professional sets include everything you need to outfit a Large Scale, IMAC, or TOC sized plane. Your cost would be $399.95 + S/H for everything you need for the 33% Extra ... batteries, charger, and testing equipment!!! Drop me an email or a call so I can get you more info.
Concerning the built in charge safe circuitry Duralite has chosen to include the design of their packs ... This is something PowerfLite explored, but we found in our testing that this was not a viable design to offer to not just the R/C industry, but to our government, military, space exploration, and robotics customers as well.
We decided that it would be safer to include the charge safe circuitry in our chargers as opposed to the packs themselves. The main reason ... the more circuitry that is added to a battery pack, the greater the chance that that pack will develop an issue at its most critical time ... IN FLIGHT. In addition, the added circuitry to the pack is under constant vibration and other harsh conditions which could cause the charge safe protection to fail or become damaged. If this happens, there is a chance that the user could experience critical issues the next time the pack is charged. Our chargers are designed to safely charge our batteries as well as any other Lithium Ion pack that is within the same voltage (i.e. cam corders, cell phones, digital cameras, etc.). In other words, your PowerfLite charger is not a stand alone, single application system that is proprietary to JUST PowerfLite Batteries.
With regards to in flight battery pack failure due to in-pack charge safe circuitry ... I am in NO way saying that Duralite's products are prone to this issue. Duralite markets and sells a nice line of products. We hope that open forums such as this will allow both our companies to get the word out about what we offer.
