Default New to lipoly's

I was just wondering about how long it should take to charge a 5000 mah core rc lipoly and is my triton charger good enough to do it.I am going to buy a balancer soon

I used to use a triton. Get a inline balancer like the Hyperion LBA10 I think it is.
What S battery is it?

If I remember right mine took a little over a hour. Depends on which version triton you got for how fast it will go. I dont remember but I think the newer one has 7 amp charge and the old one was 5. Either way you should be good to go in about an hour. Get a balancer. They will protect the battery incase the triton goes nuts.

Mine has a 5 amp charge rate,and it will when I charege nimh but when I charge these lipolys I can only set it to 2.5 amps and a lot of times when I look at it it is only charging at .2 amps do I have it set up wrong or what

Notes about charging LiPo and Li-Ion batteries:
• Triton2 automatically sets the charge current based on the battery’s 1C rating. Therefore, it is very
important to enter the battery’s exact rated capacity (in mAh) in the programming. For example, if a
capacity of 600mAh is entered Triton2 will set the charge current at 0.6A (600mA). For a capacity setting
of 2500mAh, the charge current will be set to 2.5A (2500mA). If you do not change the factory default
battery capacity value, Triton2 will charge the battery as if it’s rated at 350mA (0.35A).

I pulled this out of the Triton 2 book as thats all I could find. Make sure the pack size is set at 5000mah. Then the triton will automatically charge at 1C or 5 amp. Any lipo charger near the end of the cycle around 95% done will slow down the amp rates lower and lower until the pack is done.

Mine is the original triton but hope it is about the same as far as setup I did go in and change it to 5000 on this battery I will see what happens this time the first one stopped at 2100 and that is the setting I had for some small ones I had for my mini t.What is a better charger for the bigger lipolys

The original Triton charges at the lower rates only.. which is ok.. just will take about 2 hours for that battery...

The lipo charge method starts out at a higher amps then steps down towards the end when it reaches 8.4v for a 2S (2 cell) pack.

0610iNet is a great charger - its a 250watt output charger and will handle 6S 8000mah lipo with power to spare. I use one and I can charge my a123 5S1P pacs at 10amps and be back running in 30min (2 pacs). You will need a good power supply to run it at max power. I use a Rad Shack 13.8v 25a supply for mine which provides more than enough power.

Just about any LiPo when charged at 1C will take approximately 1hr. This is the same for 800mah as it is for 8000mah.

For off-road use you can generally pull it any time it hits the CV mode where the amperage drops way down and the voltage goes up. This is typically 90% or above capacity.

For on-road/oval racing, you will want the pack to be peaked around 8.44v so you need to let it run it's full 100% charge.

Mine will get it to the voltage just not the mah's,both of them cut off about 1900 mah's and they are 5000 not sure what I need to do it will charge at such a slow rate no matter what I set it to that most time it will just kick off after about 1 and a half hours

If your charging at the highly recommended 5A the full charge normally takes anywhere from 40 min to one hour, as for balancing take your time in getting one. Those packs only need balancing once every 50 or so cycles. The astroflight blinky is a perfect balancer

The Triton is as you say a max of 2.5 amps. Here's how it "should" be acting.

Push both buttons to get a starting voltage before charge if desired (it will give you an idea of the remaining charge before you start)

When rate is set to 2.5 amps and lipo is selected it may take up to 10 minutes to ramp up to the full 2.5 amps.

It should stay at 2.5 amps (fan running over 2.4 amps) until the battery reaches 8.2 - 8.4 volts.

After the top voltage is reached the current should ramp back down to the minimum (can't remember what it is, maybe 100 ma) as the voltage is maintained at the top figure.

from pg 13 in manual (this may be happening)

If this time limit is
reached before the battery reaches peak/full charge, “Time limit over” will show on
the display and you should NOT assume the battery has reached full charge. It may
be necessary to increase this time delay setting to allow the battery to properly reach
full charge in the future.
