Lipo Question

[cougarfan09]

I got the Apogee 1500 2 cell lipo pack, it says that the pack comes 50% charged. Do i need to discharge the pack before i charge it for the first time.

[kschauwe]

No, just charge it.

thanks, bout how long should it take to charge

Depends on how fast you charge it. If you charge at 1C (1.5 amps) and it's exactly half charged, it should take half an hour.

yea thats the good thing about lipos is u dont have to discharge so thats y i love lipos cause of that and there just better

I hope a lot of users are not using a regular chargers and doing the math to figure out charge time.

There are a lot of questions asking how long to charge my lipo? not saying this poster is, just an observation and warning not to.

no, i use the ice, it was just late (11:00 our time) and i wanted to know about hoe long it would take.

Ok,I think that the ice also does the math for you and may be called "expected charge time"

Come to think of it , I've never used it before. Maybe it is only with stepcharging?

It is not like NIMH. The last part of a charge takes much longer. The AMPS will drop as you get to the last of the charge. So it will about 10-15 mins for the last 10% of a pack(Assuming a 1c charge rate.). When you are looking at stepping from say 4 amps down by .1 amp until the amps hits 0 iut will take some time for little mah.

The first 90% is fairly straight forward. Max amps and it adjust voltage until it hits 8.4 . Kinda like a nimh charger from my experience.
