Default Yeah Racing Lipo .... 0.5C charge rate??

Hi guys, i was reading at rcmart adn found this about their 3200 Lipo batts...

It says that for the first 8-10 charges, they should be charged at 0.5C...after that 1C normal charge...


Is this real??? Or should I just stick with the 1C charge rate.... as any other Lipo??

Thanks!!!

This is very interesting indeed. I say go with what they say for performance as well as safety purposes.

They clearly know the LiPo so go with what they say. That is the problem with buying cheap LiPo's. The way I look at is that with LiPo you only need one or two, so you might as well buy something halfway decent because they last a few seasons. For another $10 you could have bought a Trinity. As much as I hate trinity, I would take them anyday over a Yeah Racing.

From what i've heard the Trinity LiPO is no good. It has a built in cutoff which will cutoff under hard acceleration of a low turn brushless motor.

I think you heard wrong
Run both Trinity and SMC Lipo's and realy cant tell the difference between the two on the track.
I watched Pauly working on his mod setups running Trinity Lipos with out any problems.

The problem with the Trinity with the built in cut off is true, it happens with mine if I run anything lower wind than 13.5.

This may or may not be the case for some...

Some drivers found that if the battery strap was too tight and applied too much pressure to the battery, the LiPo cutoff would activate. Guess excess pressure on the battery case somehow connects the cutoff circuit. I don't have a Trinity LiPo, but this was posted by a driver or two on the Carolinas RC forum quite awhile back. FWIW

Is this only with the Trinity 3200 packs? or does it apply to their other packs?

Reason i ask is because the 3800 is the Intellect pack and carries a differently formatted part number than the rest of Trinity's packs.

I have run the IP3800 with 3.5T and the ESC cutoff triggered 1/3 lap after the end of a 5 minute run on a rather large track. I know this to have been the voltage cutoff on the ESC and capacity wise I also used 3800+ mAh from the pack during the race.

Curious as to what other lipos have built-in protection circuitry and what exactly it does... like my LRP 5300 Comps I use, nice circuit board inside but what does it do, if anything?

I heard that lipos are made in 1 of 3 factories. Is this true?

The cut off is use less and the trinity has a high internal resistance





The battery that RCSTEVE posted is actally interlect and they are some of the best on the market
