About a week ago I had ordered four 3 cell 11.1v 1250mAh
lithium-polymer batteries from a fairly new online company called
Common Sense RC. These batteries are from the budget line, and run $31.50/pair. I have spent many hours combing the web and magazines for decent lithium-polymer battery deals and found Common Sense RC to be the best so far. They offer many batteries of all different cell counts, discharge rates and voltages.
As I mentioned above these batteries are 3 cell 11.1v 1250mAh batteries with a continuous discharge rate of 8C. They weigh 85 grams, just slightly more than the stock NiMH battery on E-Flight's Blade CP helicopter. When compared to the popular (for Blade CP owners such as myself) E-Power batteries from
HeliDirect that feature a lower 7C continuous discharge, are 15 grams heavier and cost $1.99 more Common Sense batteries are a no brainer.
The budget line comes with a female Dean's Ultra connector and a balancing connector. Since the Blade CP uses JST connectors I decided to create some cables from CheapBatteryPacks.com's
Adapter Creator. In order to connect to the E-Flite 4-in-1 I needed a male JST -> male Dean's Ultra adapter made, and the Adapter Creator made it extremely easy to do so. You could also "hard" convert your 4-in-1 by soldering a male Dean's Ultra in place of the female JST.
Flight time with the 1250mAh battery was clocked at 23 minutes with my Blade CP (stock other than 8T E-Flight motor and
JCS Hobbies' Plasti-Blade). My thumbs nearly fell off during this time doing lots of forward/reverse flight, hovering and fast altitude changes in an attempt to wear the battery down. The flight time is so good I'm kicking myself for buying four of these batteries as two is *plenty*. If you are an intermediate heli pilot these batteries will allow you a massive amount of practice time.
While browsing their website today I noticed they are now offering 20C continuous discharge batteries. That's a little extreme for me at the moment, at least until I get one of those fancy Kyosho Caliber 400 helis.
So whenever you are on the lookout for some new lithium-polymer batteries give
Common Sense RC a look, you won't regret the price or the performance!
