Just a couple of points.... I recently swithced to lipo (SMC 4000 of course). I bought a Hyperion duo (great charger) however, in a moment of mental weakness I decided to use the provided hyperion balance plug board instead of stepping up for the correct adaptor. This brain fart cost me a brand new SMC 4000 pack and taught me two things.
1) Incorrect balance adaptor provided numbers that were incorrect and still allowed me to charge the pack well enough to destroy it. Hmmmmm
2) The pack went south, yes, but not in a ball of flames and a mushroom cloud like some would have you believe, the case just opened up a little on the seam as the cells expanded and the voltage numbers went into the toilet.
I'm not afraid of LIPOs as a result of this experience (read stupidity) but I have a greater desire to follow the correct and safe process when charging them.

Quick question 4 u guys?
What do you guys think about the lrp pulsar 3 ?
And if u were to pick between the lrp and the hyperion, which one would u go with? and y.
And yes i know the lrp does not have a balancer, so i went ahead and got a maxamps ballancer. Thanks guys.

Sorry to hear about that. You should of contacted me I would of helped on the price of a replacement pack. I feel bad when racers have bad luck like this and if I can help I will gladly so so. I assume you now have the JST-XH board ?

A charger with built in balancing will be allot less of a hassle and it's calibrated with the balancer. That being said you can claibrate the LRP with your balancer and that should work also but then if you use the charger without the balancer you need to recalibrate it so it's more hassle.

Balancing SMC with V balance--Trackpower / Orion type
After several attempts to find the right adapter, buying 2 that didn't work, I found the correct adapter for the SMC. There are a few misleading posts on this topic in this and other threads....Thought I'd save someone else the headache. Here is the correct, direct plug in, no hassle adapter that allows the V balance (Orion / Trakpower) type balancer to work on the SMC 7.4v.

Balance charging is not needed as packs should stay balance for a long time but if you do balance charge it doesn't hurt.
When we cycle our packs we use balance chargers and the reason why we cycle our packs is to make sure they are no cells with minor shorts which caus inbalance. We pick these out and send them back as these will tend to have issues.
