10XP Charger - last time buy
It looks as though Revolectrix is discontinuing the 10XP Charger and is offering a last chance buy for $125 each; received an email from them today...
Cellpro 10XP
Curious if they will design a new “10s” capable charger to take its place or if they think there just isn’t a market for a series 2x5s Charger ...

Yeah I've got a few CellPro chargers, 4S, 10S, 10XP and no parallel models.
I've also got a 4010 that I'm scared of.... lol
The issue for me about the 4010 vs the CellPro 10's, is that you cannot hook the CellPros up incorrectly when trying to do 10S (usually a pair of 5S's for my Pattern ships). The CellPro will merely inform you of an issue regarding the cell count. You do it wrong with the 4010 and you let the magic smoke out of things....

I have two CellPro 10XP chargers and I love them! Being able to parallel charge on each charger using their MPA board is simple and effective. I can charge 6 5s 4600mAh packs/charger in about an hour and a half.

I don't think so, almost everyone these days is doing the Parallel charging thing and do not care about being able to do a series charge. So, IMHO, FMA/Revolectrix has just decided on parallel charging units only and last I heard, the International boys are dead set against 12S in F3A. I think they're scared of having their precious YS birds beaten on a regular basis.... lol

“Batteries that are charged in parallel are not covered under warranty.”
Curious how they can determine if a battery was charged in parallel ...
I’m also curious why parallel charging is unsafe... I’m having a hard time seeing that

I think it is unsafe since is impossible for the charger to know the cell voltage. Therefore, balancing and safe functions are done by averaging. If one cell is too high and another is too low the high one could catch fire. Probably, the chances are small but I don't think I want to take the risk.

In addition, there should be current limiting provided between the cells of the parallel packs, so in the event that a cell does "wander off the reservation", there is a current limit/protection in place to prevent the other parallel cells from sending too much current into the weaker cell. I believe the Revolectrix MPA provides such protection via surface mount self resetting fuses with visual indicators to indicate if there is such a problem?
Revolectrix
In addition, the lead connection sequence should be followed when connecting to charge and then disconnecting when charge is complete: discharge leads first, balance leads ... then disconnect balance leads and finally disconnect discharge leads (FWIW, the first discharge lead I connect is the black and the last discharge lead is disconnect is the black as well ... charging lithium batteries is perfect for those with OCD ... )
So, I still fail to see why parallel charging, when configured correctly, is inherently unsafe. In all honesty, charging a 1s lithium battery is inherently unsafe, its just the nature of the chemistry.
I must be missing something, but parallel charging just seems to get a really bad rap on almost every RC forum and I've never understood why.

The reason I no longer parallel charge is I have had several batteries over the years where a single balance tap wire has come adrift within the battery (so not obvious) or there's a balance connector issue. When series charging that is seen immediately as a cell mismatch however, as Vince has said during parallel charging this could be masked due to the cell averaging. I do now strain relief the balance tap wires and have not had a failure since. Also I monitor the individual cell IR's every time I charge, again with parallel charging you can't get this, just an average IR of all cells in parallel.

Perhaps, but parallel charging (or even serial charging) assumes that you have first verified that each cell is within normal range before starting the charge; if you have an abnormal cell voltage, then caution is required.
In addition, there should be current limiting provided between the cells of the parallel packs, so in the event that a cell does "wander off the reservation", there is a current limit/protection in place to prevent the other parallel cells from sending too much current into the weaker cell.
