Charge Rates? - RC-Monster Forums

Well, I upgraded to a ICE charger, so now I am in need of some suggestions.

My current charger was only capable of 5 amps, so I just charged my GP3700's at 5 amps...

However, the ICE is capable of 8 amps. I know I shouldn't charge at a full 8 amps, or even 7. I was thinking more around 6 amps, or maybe 5.5.

Will going up past 5 amps have any negative effect on the cells? (by effect I mean more so than the standard more punch but less runtime and harder on the battery as goes with increasing amp rate) :eek:

I'm also going to need some recommendations with the peak settings...my old charger did all that automatically (all I did was input charge rate, cell count, and safe timer)

6 is the max you will want to charge them at. Thats what most manufactures recommend.

As for the peak. Set it as low as you can and still get a full charge. It may take a little experimenting to figure out what your charger is capable of. Some are more sensitive to false peaks than others. But start with a lower setting and if you don't get a full charge just start the charge again to finish it and the next time use a setting a little higher until you find the lowest setting that get you a complete charge. Every charger is a little different. Using a higher setting than is required just overheats the batteries more than necessary.

I have 3 different chargers and they all require a different setting when peak charging to get good results.

Well, whats a pretty good starting point? 5mv?

5mV is what I use with my Hyperion. Whatever you select, the pack should feel warm when it peaks. If it's cool it's being undercharged; if too hot, it's being overcharged.

If you can get a good charge at 5mv thats a pretty good charger. I tend to need more like 15 to get a reliable result.

But the Ice is a better charger than the superbrain977 I was using on my nimh, so 5mv is possible. I dont do much nimh charging any more though.

(once you go lipo you never go back:005: )

Yea...thats what I've heard. The only reason I got the ICE is to charge Lipo. I got the 8000mah 2S2P Maxamps Packs.
