ZIPPY 400mAh 20C single cell

 Drugos 1975 points

In my opinion you should use a 150-200 mah li-po battery.If you use a 400 mAh one your helicopter will not fly because it is too heavy.

yes u can make it own! by connecting each other!

 Drugos 1975 points

Yes,of course.

yes you can *) me and my friend do it and it works well, but you have to know. if you want du get an higher voltage you have to put it in serial, to get more power you have to put it parallel. my tip is to use an balance adapter for saver charging *)

Yes. you can find scheme on Internet. but you have to buy balance and charge connectors.

OMG nevermind...it's right up there in the specs...2C *blush*

maukabud,even it's at your own risk, i'm charging 2c without any failure and have done so for a long time with different lipo's in the market. BUT BE SURE TO USE A QUALITY CHARGER.

yes, it will give you 8amps continoues. It'll probably give you a burst, but I didn't tried that yet.

I haven't measured current but it certainly seems 20C. Very good power in a 4G3. Not quite as much as oversky, but longer flights.

 Walter 5 points

Of cause it will, but only for about 3minutes.

 A.J. Van der Plas 87 points

yes, it's 20c. You can solder them togheter to make a cheap 400mAh 20c battery. Like 2, 3 or even 4 cells!

 Jens 46 points

yep, nearly almost, mine is 1 year old now and are down at 7,2A

No connectors.

 Daniel 10 points

This batteries are without connectors!

no connectors in box.
it depends on how many cells you plan to compose from this batt. if you want to use it as a single cell - you can buy something like Pico plug, for 2S or 3S - JST plugs.
Find everything here in catalog:
Hardware & accessories->Wires & Plugs->Battery/ESC/Motor Connectors
or
Battery Chargers & Acc.->Charge Leads

no, but i use it on my micro co-ax copter. awesome! 17 min in the air. Just has ordered 6 more to make a couple of lightweight 3S lipo-s for 3D BiPlane

Actually you have to buy an "advanced" charger to charge at such low current. Most "cheapos" are 500 to 800mA.

The Turnigy accucel 6 is probably the cheapest which can charge from 100mA and upwards (search for "accucel" in the quick search). It is neccessary with a 12V supply for this charger (car battery or a separate powersupply) There is a cheap (around 10$) 12V 5A supply here, it should be more than enough.

Just a warning, charging above 1C may cause battery to heat up, puff, catch fire or even explode (unless battery is rated for higher charge current, some are), and will reduce lifecycle drastically. In any circumstance, charge your batteries someplace firesafe, and allways keep watch while charging.

 Beaufighter 1808 points

In general, a lipo must never be charged more than 1C (that is 1 times the capacity), so your 500ma charger is bit too big for a 400mah battery.

Btw, 2V is not charging voltage for lipo, 3.7V pr cell.

Buy a specialized LIPO charger:)

Dear Laurent,
the charger you have (for Walkera 4#3b) charges the original 3,7V 400mah cells, so you can youse them for these 400mah cells too. But normaly you´ve to charge a lipo with 1C or less, in this case with 400mah or less. You CAN upgrad this at your own risk - but its not recommended! But i charge all my lipos at 1-1,25C, no problems - till yet!
Best Regards
Andy

You can use the sock charger! i use them too! It is no problem and works
