Hey guys, don't know if this was covered earlier in the thread but I'm looking at one of the smaller 12v LiPo chargers (15/$20) similar to the cheap ones you can get off eBay (but the one I'm interested in is made by a reputable flight company). Has anyone done a side-by-side comparison of this charger to see if it charges any faster/slower or better/worse than a bigger charger like the Advantage Carbon? Just curious

Default LIPO Charger Reviews

Frank,

Check out this website http://www.rcgroups.com/links/index.php?t=sub_pages&cat=231 . There is also a "Batteries and Chargers" Thread. Most of the info deals with airplanes and helicopters so usually the lipos are of smaller capacity. But read over the problems that people have with lipos. I think that lipos are the wave of the future, but there is a learning curve to them.

Hey, thanks for the link That guy actually reviewed the exact small charger I was looking at. He basically recommends it for 'small' batteries and says it does do exactly what it says (automatic cell and voltage selection). My only question now is, what is 'small'? I'd guess that a 4800mAh battery will not be considered small, especially since the small chargers he reviewed have basically receiver pack charge leads.

try the prodigy II from ripmax (very small unit aswell)
60.00 (approx) 5 a max does `ALL` battery types , tell it the capacity ,it does the rest ,back lit display , no fancy pant`s charging thingies , just like ronseal varnish `does exactly what it say`s on the tin)box)`

i have a ICE aswell but the prdigy is so much easier to setup & go with my peak li-po

Rick,

How much would you expect to diminish the life of the pack by charging at 7.5 or 10 amps. How many times do you think you could charge the pack at those rates before it started to take a hit in performance - 50 charges? 100 charges?

I realize this would just be a guess on your part but I am curious. People say at 4.8 amps it can be charged 500+ times. Frankly, that would last me a few years, at which time the battery would be dated. If I can get somewhere around 150 charges I will be more than happy.

Thanks in advance for your input.

Hi,

Charging at higher rate, i.e. quicker, would be great! What charger do you use for 7.5A or 10A?

Thanks!

NiMH cells wouldn't last very ong with 10A charges, so 6A would most likely hurt the pack pretty quickly. Why do you want to charge above the optimum rate anyways. At 6A you're only reducing the charge time by 12 minutes and you don't get any extra power from the batteries. (less maybe if they overheat)

Default CC/CV Graph

Found this on Apple's site, but it is the same for all lithium batteries. This helps clear things up with how the CC/CV charge works.

Likely that it had a charge in it when you received it. I believe I read of others experienceing similarly.
