I would recommend visiting the RC group forum and do a search about LiPo + balancing. I’m not an expert on this topic either.
This is what I have as a charger

It does charge Lipo’s although I’m wondering if I will have issues down the road without using that mini plug Jim mentioned earlier.
Crap well I might as well buy a new charger, what do you think of this one?

I’m kinda lost as to what features I need besides the Balancing feature for Lipo’s
Thanks again!
This hobby king website is kinda dumb it makes me seperate international products with domestic ones… how is this my problem? CHEEZY! oh well
I have a charger, Lipo battery and Ubec on the list.
Be aware that most chinese chargers are crap which will broke if used at their max specification (43$ for a 150W seems way too cheap).
I really like turnigy products but I don’t put must trust in their chargers.
I’ve buyed a T2M Wizards X6S on ebay for around 50 euro (100 euro in traditionnal shop) and it charge my Lipo and LiFePO (but it also does NiMh, NiCd, Pb, Liion) and it’s a 50 W with built-in transformer.
just take away around 1/3 of Turnigy declared parameters (for BEC for example) and should be ok.
i have comparison between Jeti BEC 5A (have 2 of it in my hex) and Turnigy BEC 8A (take out of my hex and put Jeti) and Jeti works muuuch better but price is x3 to Turnigy
using this for pumping packs
Well I just bought the turnigy one, along with the battery, charger, and bullet plugs for making a pack connect to the botboard. I ordered the Turnigy one as Zenta had ordered one a while ago and mentioned he had good luck with it.
The battery wasn’t very much either, I’m guessing because it has a low discharge ability before it goes Chernobyl on me, which is fine since all I’m using for is servos… big mean ones!
how many Cs? because my “nice” and cheap chinese MG995 servos might take up to 10-15A all together.
this way you may get much more interesting Chernobyl effect (when discharge rate is higher than declared on pack)
I believe Jim mentioned that the Phoenix draws between 7-9 amps at full load.

This fits within the frame of the Phoenix… I have the risers that split the top and bottom plate further apart.
Originally it was 44mm between, mine is 52.5mm.
do i see correctly 20-30C discharge rate?
for 5Ah accu it gives 100-150Amps looks suspicious for me
or if only 30C is a peak and 20C continuous, that might be fine
Yeah 20C is more then fine for just servos.
But apparently that pack I bought online says 4C max charge rate and on the battery on the rear of it says do not charge faster then a 2C rate.
… I’m still waiting on my new charger and misc bits to wire up the phoenix…
Also still trying to figure out a solution for lynxmotion.net/viewtopic.php?f=21&t=7325&start=0
oh come on, 2C charge gives 10Amps, with 7,4V pack its 74W power - quite big amount.
2 nd - yeah i saw this topic, but don’t feel competent to take a voice
I would recommend to not charge above 2C if the pack say so. I believe the 4C is a typo.
Well it’s not the first time Ive run into a problem like this from an online site…
How long does it take to charge a 5000Mah pack at 2C anyway?

theory says around 30 min but practice says a bit longer because after charger goes from constant current mode to constant voltage it charging until current dropped to around 0,1A but all depends on charger and battery itself
