Thanks great work


Is it possible to order by two parameters, ex. first mAh end than mAh/g?

Thanks a lot.

Bye, Mirco

Mirco,

Not at this time. You can filter the results by searching within one column (search for "800" in mAh) and then sort those results by another column (i.e. descending by mAh/g).

.................................................. ........

For those just jumping on this thread, you can check out the electric flight lists which I've posted here:

http://www.progressiverc.com/Research.html

There are currently lists for 2S to 15S lipos, gyros, ESCs, receivers, balancers, chargers, watt meters, etc. with product specs to aid in your search for the perfect component set-up.

Cheers,
David

Hi David,
I'm new to RC airplane flying....I literally just bought my first plane at the beginning of October, 2007. In reading everything I could get my hands on to build up my knowledge, one area that was very confusing was the issue of batteries. So many different adds claiming to be the best, cheapest and lightest weight, etc.

I have to say that I, and I'm sure the other members of this forum, really appreciate you taking the time to share the information you have gathered.

Happy Holidays to you and your family.

Amazing work. Thank you, thank you.

This may also affect prices in a good way. Competition is keener when comparisons are handy. You could become the Kelly's blue book of lipos.

Thanks so much.

you may end up with Carpal Tunnel but you will never get every available battery listed especially with pricing

That being said its a noble (albeit slightly insane) pursuit and the spec comparison is handy even if the prices are only relevant until you hit the enter key.

What do you do when a battery (like Polyquest or TP) is available at different prices from different dealers? I wouldn't worry about it, just put the mnfctr's price or do it as you currently are.

I don't think you should feel obligated to keep current, it might eventually burn you out. You could let the community give you the info. If any company complains, let them provide you with current data. You could let dealers advertise specials (non-standard prices). Pretty soon you'll be the place people go first when looking for lipos.

Besides, the exact price is not important. The list tells us the main mnfctrs, and a good idea of relative pricing and quality of different batteries from different sources. Though exact prices may fluctuate quickly, that doesn't matter, when the list can tell me what brand and seller usually has the best batteries at the best prices. Your list already does this great, and that kind of info won't change rapidly.

Thanks again for this.

My thoughts exactly, Jim. It was initially intended to serve only for comparative data, but the low price links are also useful when shopping around as there are so many sources and options.

As a rule, I list the lowest price I have seen for each item. If a lower price on any item is brought to my attention I will make the update. I know that vendors and dealers have used the price listings to see how competitive there products are and to make changes to or price their product line. Competition is good.

I have been hard at work adding hundreds upon hundreds of motors and servos to the lists in an effort to cover all the possible options. Complete listings are now finished for every single Neu and Scorpion motor made with all the pertinent motor parameters. Two new lists are being finalized and will also be posted soon. One of the new lists will show the different heli models available and the other will be an extensive list of online sites, categorized with information about each one.

The lists are published and updated on my website, ProgressiveRC.com. Here is a snapshot of where the lists stand currently and how they have grown in recent weeks - enjoy!

David,

Thanks for this excellent resource. I have one recommendation for you - instead of filtering with a search function (allows exact match only), can you implement a filter where we would specify a min, max, or range for specific columns? To me the first places this comes to mind would be current delivery, weight, and size.

Sorry if this was already recommended, didn't have a chance to read through the entire thread.

I appreciate the kind words and support. Currently the lists are generated directly from Excel spreadsheets with some interesting code that allows for sorting and filtering. I appreciate the suggestion for filtering by ranges, but it is currently beyond my coding skills to integrate this in as designed and would probably require me going to a database type information structure. I will certainly keep this in mind moving forward. If a better mouse-trap becomes apparent, then transferring the data to another format should not be overly difficult. For now, the best solution is to use the sort feature (by clicking on the column headings) to sort the data and then view the desired range.

I have added the balance connector type as part of the description for each battery as suggested by a user here on RCGroups. Here is a partial screenshot of the 3S LiPo battery list filtered by "2100 mAh" and sorted by mAh per gram as an example of what's available:



If you see any updates or revisions that need to be made please let me know.

Cheers!
