NEED ADVICE ON LIPO"S
 

hello peeps i need advice on using lipo such as which brand of lipo is good and how long it takes to charge and what about the cut off? what voltage should it cut off at.
at the moment when i was reading the accorn brand lipo instruction i saw that the cut off should be at 6.4 but my esc cut of at 6.25 only so dunno if advisable to use or not someone plz help advice please
i am using rooster esc on a tto1 haven got lipo yet planning to get a few in a few days time so need advice
your advice would be most appreciated people THANK YOU;)

It takes almost the same time as a normal NImh charger. As long as it does not go below 6v for 2 cells it should be fine.

Maybe you can check out the hobby shops in Singapore or Singapore's online store http://www.quantumracing-rc.com/

thanks arahawk
 

Thanks arahawk

important question
 

what will happen if lipo left in table never use for a long time will the voltage drop after while and will the lipo catch fire? and anyone can recomend brand of lipo to use

It won't catch fire just spoil. U can store it at 3.9v per cell. Just check once in a while that the cell won't drop too low.

For 1/10 get IP, zippy(from hobbycity? N etc depends how deep your pocket is.

1. brand of batt.
technology now is quite gd lah, so any brand of lipo is gd enuf
I'm using ORION 3800, i go for these batt cos of its carbon looks only:sweat:
2. how long it charge
normally, its charging not more than 1C, meaning if ur batt is 3200mAh, charge at 3.2A, <1hr to full charge
if batt is 5000mAh, charge at 5A, <1hr to full charge
unless otherwise stated, eg. my ORION state there, DO NOT CHARGE LESS THAN 1C OR MORE THAN 2C, meaning, >3.8A or <7.6A, but my charger max is 5A, so i charge 5A, <40mins
3. do not discharge ur batt to less than 3V per cell, 2 cells = 6V.
when on load(batt is connected, motor is running), batt voltage will be lower, when off load, batt voltage will rise slightly.
so, when ur ESC read 6.25V, it cut off. so its time u charge the batt, it voltage shd rise a bit, probably to 6.4V.
4. lipo self-discharge can be as low as 2% per year, so , how long do u wanna leave it on the table?

hey thanks alot to everyone
 

hey thanks to the all the bro's who have given their advise and you advise has helped me quite alot and thanks to ur advise i already got myself 3 packs of lipo cheers people :)

Anyone heard of Vampire Racing they also carry Lipo battery.

Hi piravin,
If you need some LiPo with fast charging time, you can look into H-Energy LiPos which the charge current can be up to 2C (meaning 5000Mah can charge at 10Amps), also with some good feedbacks on it. But 2C is not recommended which it reduces the lifespan of the LiPo..:)

Li-Po batts
 

I have a Li-Po batt that has not been used for awhile and it has bloated slightly.

1) Can it be 'Saved' ? If so, how?
2) Are Li-po batteries always to be balanced charged? Do all Li-po chargers offer balancing?

Pls advise.
Thanks.

Do all Li-po chargers offer balancing?
hey bro deppends on the charger not all charger has balancer bro thats what i know for example t15 it does not have balancer need to buy seperate balancer whereas the t15 plus already has balancer

i also thinking of upgrading to lipo but dunno why the price for 5000mah 2s1p is cheaper then the 4000mah 2s1p same brand lipo somemore :S any idea why ?

It could be different C rating. Take note of the C rating, some brands indicate burst C rating instead of constant C rating.

You can try acepow 5300 mAh 30C (40C burst) available at Winnie's shop.
