Hi everyone  ,
As promised earlier,this is a comparison b/w the Li-ion battery pack vs 'the rest of them'.

Note:This post is intended just as a comparison and NOT to prove one is better than the other.
           The hobbyists may relate their requirements and get a suitable battery for them.For further support,please contact us.

Here,a standard Turnigy 3s battery is compared with the Li-Ion 3s battery pack,that we offer.
Both the batteries have a rated capacity of 5000 mAh.

Given below is the link of the battery,selected for comparison.
https://hobbyking.com/en_us/turnigy-5000mah-3s-20c-lipo-pack.html

The other one is our battery:Dronish 3s 5000mAh battery pack.

1.Rigidity:The Dronish battery has each cell covered in a metal casing(just like the cells that we use in the TV remote and wall clocks).Hence,it's much rigid than the 'much exposed' Turnigy battery.
The Dronish battery can sure take a hit without any damage,but whereas if you do the same thing with the Turnigy,that will be the last thing you would be doing it.

2.Weight/Mass(for physicists):The weight of the given Dronish battery is just over 290g,whereas the Turnigy battery weighs 346g
Hence,despite being in a metal wrap,the Dronish battery pack is much lighter than the Turnigy pack.

3.Performance:We rate THIS Dronish battery at 70A Max. continuous (<60sec) and 140A burst amperage(<5 seconds).Here,the Turnigy promises 100A max continuous and 150A burst amperage.
And one might say this is where our battery lacks.We honestly admit it.But the real truth is,nobody ever really goes to a battery's full potential.On top of that,the turnigy batteries are pretty much over-rated,every battery in the market is.
Every expert or intermediate flyer or racer would've noticed that your battery doesn't last more than 100 cycles.Technically,all the Lithium based batteries are expected to last 500-800 cycles(maybe more than that).And if you're clever,you would figure out those Turnigy or any other brand batteries are over-rated.If they were correctly rated,then they would definitely last this long.
So here,we promise a battery cycle of 500 life cycles if used in the correct manner,if not abused.

4.Safety:This was suppose to be the first one,but we felt that would make it less interesting.
Unlike the Turnigy or any other lithium polymer batteries,the Dronish battery,upon over-discharging,would NOT puff up and create an explosion.
We all know how dangerous a LIPO battery can be,if not used properly.A thermal fuse is present inside each cell of the Dronish battery,which,upon subjected to unhealthy over-discharging,would result in the opening of the whole circuit.So,you're safe  


5.Price:This is a major part when it comes to buying a battery.We promise to sell these battery in almost the same price range of a LiPo battery.So,there's no major reason as to why not try one  

So,now you know how safe you can be,and you've a better option over it.

We would love to hear from you guys about this comparison,and we request to shoot whatever comes into your mind in the comment section.
We will give a catalog of the battery packs we intend to manufacture in bulk.

We have a lot of new batteries in this segment coming in.

Here is a short note for the Local Hobby Stores :If you're interested in our battery,please message us personally.

At the end,we thank you guys for going over this message.

Best Regards,
Team Dronish                                                                                                                                                                              

@ team dronish.....a price point comparison would be of great use.
and some pics too

very impressive claims -

what would be more credible - have a independent verification / review
by an experienced modeller ..... rcpilotacro / sundaram / or sanjayrai

Hi Saikat,
We'll be sending a sample to Robu.in for testing.Let them decide if the claims are accurate.Anyways,we would like to send some samples to you,if you're interested to pay(just 75% of the actual price).

Best regards,
Team Dronish

5000 mAh is used by Drone fliers. For the majority of Fixed Wing fliers, the most popular size would be 2200 mAh, and current draw would be up to 40 A. Also give some specs about the 2200 mAh you offer

Team Dronish: I posted in the forum as representing a common concern. We all wish you the best in your venture. But it would be better to post your reply in the forum, not as a PM for the benefit of all

As already mentioned,the price range can be expected to be almost the same.Altered by a few hundreds at max.Sure we will provide the whole price list within a few days.

Best Regards,
Team Dronish

Few hundreds are not always less it depends on actual price of battery. For a 10Ah battery difference of couple of hundreds between a lipo and dronish doesn't really matter but it won't be a case for 2200mah. I think it would be better if you mention the price difference in terms of percentage rather than actual price. That could be more clear. One more thing is what lipo price you are comparing with. Indian lipo batteries price or hobbyking lipo battery as batteries sold in India are always costly.

Price comparison is done with the Indian hobby shops.Well we won't be have a 2200mAh battery pack.It would be better if you mention the amperages and the weight.Price will be the same.The mentioning of increase in price is said because at first we intend to sell through the LHS.
Anyways,a catalog will be published in a few days.

So basically your batteries use Li-on battery 18650 , please mention the cell make and model.

If they have genuine batteries then the datasheet of them is plenty, we just need to make sure that your supplier isn't giving fake ones, which happens even unknown to the supplier.

So basically your batteries use Li-on battery, mostly. 18650 or 26650 or 21700.

Yes sir.We use 18650 cells.But they're good in a lot of ways.
Allow us to serve you 

Best regards,
Team Dronish

I am intrested but need to know which make cell and model you are using.

I have been saying LhS from a long time to get 18650, glad some one started.

Hi,
We use the genuine batteries by LG,SONY,PANASONIC,SANYO,and SAMSUNG.All of these batteries are Tesla grade cells,and are individually checked by us.So,no worries of receiving fake ones.

I believe its better to tell exactly what battery make and model is used in each pack.So people can look at the datasheet and various indepth review to know which make and model fits their needs.
For eg a battery from say samsung could give lower amps continous but it runs a bit cooler vs say a battery from Sony which is the discharge king but runs a bit hotter.

Or also better just make a battery pack as per customer desired cell and make and also sell 18650 batteries cells individual since I and many other use it for extremely powerful flashlights.

Hi,
Appreciate your suggestion.But for a regular hobbyist,it's hard to just look from a spec sheet and choose their required cell.On top of that,we select the best cell in the market,and order that particular cell in bulk,because only then,will it be worth buying.Else,we will all end up giving twice the cost of a LIPO.
Also,almost all remarkable companies under-rate their cell.
for eg:Samsung 30T 21700 is rated at 35A whereas it's actual rating is between 40-60A.
And it's always better to choose the best battery which run at cooler.

Fact is,you just need to tell your requirement and we'll get the right battery for you.

The battery depicted in this comparison is Sony VTC5A.

Best Regards,
Team Dronish

Sure....We can provide you with genuine individual cells.But you have to intimate us when we order it.Each order takes at least 20 days to get delivered,minding the shipping cost is extremely high.

@team dronish

All this is just advertising hype to generate interest.

Now kindly post your specs and prices.
And delivery times.
Will you have stocks?
Will you supply immediately?
Or import after order is placed?

Hi Mr.Iyer,

All of this is ain't hype.We have tested it ourselves.We would be mostly selling through Robu.in first,hence we can't say the price for now.Give it a few days and we ourselves will PM you.
About the stocks,our raw material has a shipping time of maximum 20 days.Leave the rest to us.
And No,we'll have the stock and you most probably won't have to wait for it.That's a promise.But if you go for a custom-made battery pack (yes we support it),it might take a little more longer.

Best Regards,
Team Dronish

Thank you Mr.Iyer. We had a small discussion within our team and came to a conclusion that we could produce upto 1000 pieces per month.
We expect to have a tie up with hobbyking.com,horizonhobby.com and flitetest shortly,that is we expect ourselves to go global.As a result,we've decided to punch the production line to 10000-15000 pcs per month.
We really appreciate your message as it helped as think a step ahead.

Team Dronish

Hello Team Dronish,
First of all, all the very best on your business initiative. Hope you live upto the hype.

As prospective customers, we would like to know more. Why don't you introduce yourself and your experience in the industry(doesn't matter if you are new).

My sincere suggestion would be to just show us what you have got. Post us some videos or documents comparing your batteries with others in the market.

You have got a good platform. Good luck to grow your brand in a honest and a trust worthy manner.

Thank you Raj. That was really encouraging.Sure,we would introduce ourselves once we're done introducing all the products.
And about our experience,we're just a bunch of hobbyists,and we were looking for a change.Well this is no change,as this was already in the market for a long time,but in another industry(vaping).So we just had to reroute it to here.
We have some amazing ideas about the next gen. Lithium based batteries. Since,starting from scratch or the base chemistry,is not financially viable,hence for now,we've decided to improve it. Those 'amazing' ideas include liquid cooling and extreme burst and continuous discharge rates.
We will keep you updated about our researches.

Best Regards,
Team Dronish

Here's the new post for designers and artists.

http://www.rcindia.org/rc-general-topics/designing-of-our-new-battery-logo/msg271483/#new

I was always afraid to use LIPOs......Nice that someone has come up with an alternative idea.
All the best from my side.
I suggest you send your battery packs to some of the well reputed members,and let them test it.By that way,you can earn a huge trust within the forum.
