Yeah this isnt over charging a lipo....its getting it warm and peaking at 8.4 volts....and they are faster that way. A warm lipo is faster then a room temp lipo from everything that I have heard and seen....they are not over charged they are just warmer then normal.

Kevin, you can't think of LiPo Charging like you do NiMH. Charging at a higher rate will slightly shorten the charge time at a cost of pack-life. HOWEVER, unlike a NiMH charger, as a LiPo pack gets close to "peaking" the charger reduces the amperage output gradually. This increases capacity while preventing the pack from exceeding the voltage. A LiPo also doesn't get warm while charging UNLESS it's about to go BOOM! If you want to pre-heat your packs ahead of time the charger will not be the source of what you're looking to do. You'll need to use a heating pad or covering iron or some other method. I've used the Losi 1-5 Cell LiPo charger for awhile and like it, and I've also used the Orion Carbon Advantage and the LRP Pulsar 3. I like the Losi because it'll also charge my 3-cell plane packs while my Orion won't (can't remember if the LRP does or not), plus the Losi has the balance ports too.

I have never heard of preheating packs. I would be to scare of this happening: http://www.youtube.com/watch?v=Gboge17PNBk
If you wanna try it, do it outside and have the fire department on speed dial.

As long as you don't overheat them you "should" be ok. I warmed mine a little at the Nats and they did seem a little peppier

Kevin, the reason why I picked the 610C is because of the internal balancer. I have the orion avionics charger and the balancer and the 610C is approx the same size without the extra balancer. Here is a couple of pics of my buddies 610C black edition Enjoy your new charger! When you get it.

Sorry to tell you, warming your LIPOs does help the preformance of the battery, but this is not need for club racing unless you are looking for the little extra.... The temp of warming them up is around 130 F... There are many posts here on RC Tech on this topic... You do not need the fire department on speed dial... Also it is STRONLY recommend that you put your LIPOs in a sack or something when charging no matter your way of charging, because it protects when something goes wrong...

Since I live in Florida, I don't worry about it in the summer. The pack will be at 100 on its own.

Thanks....I got mine on order...does it come with the balancer plug setup or do you need to order that on its own?

Kevin,

It comes with a circuit board that has 2-5S balancing ports. You can plug in Thunderpower balancing plugs and the SMC balancing plug too. I have an orion 3600 that I am making my own balancing plug (like my buddies pictures above) and I will make one for the SMC battery too.

That's entirely normal. A LiPO charger will use a Constant Current/Constant Voltage charge program. The first part of the charge is at a constant current until the pack reaches 8.4 volts, then it tapers off the current maintaining 8.4 volts (that's the constant voltage part) until it decides the pack is full.

LiPo's don't usually get warm on the charger under normal conditions like NUMH cells do.
