[NSRCA-discussion] Cell Pro chargers

Mon Feb 9 06:27:45 AKST 2009

Sorry, I don't know if they will work on the 10S. I only have a couple of
the 4S chargers to use them on.

Is that adapter compatible with the 10s? The website says it is for the new
Multi4 charger and not compatible with the cellpro 4s.

FMA now makes a nice adapter to charge through JR, Futaba, Airtronics, Small
Deans, and Molex plugs. You could wire a large Deans adaptor set up also
from one of these.

I also have two Cell Pro 10s chargers, though I got them after last season
and have not used them too much. I really like the fact that they brings
cells up to peak individually. With my TP1010, which I've used without
problem for 3 years, it's a bit of a hassle to get perfect balance because
if one cell is low the charger takes all other cells to capacity then drains
all cells to match the low one(s). Normally this isn't that big of a deal,
but at times it can take hours to slowly discharge all cells down to the one
that's low (and I'm not talking about significant delta).  Then if you want
to be at peak you have to charge again. 

The only real downsides I've seen to the cell pro so far are:

1.       You can't use it to discharge. Recently I'm trying not to charge
unless I know I'm going flying the next or the same day. If I charge then
I'm not able to go fly I like to drain the batteries down to the suggested
storage  level. The Cell Pro's don't discharge so I've kept my TP1010's so I
can discharge (though they are WAY slow at this).

2.       You can't use the Cell Pros w/o balancing taps. I have some LiPo RX
packs that don't have balancing taps and I was able to charge these at the
field with my TP1010 but can't with the Cell Pro. Not a huge deal, just a
bit of a hassle.

CellPro advantages:
1. measures internal resistance of each cell
2. charges each cell individually for guaranteed balance at the end of the
charge cycle
3. external usb link to upgrade firmware and additional monitoring features
when connected to a computer

not so good points:
1. seems like more component failures than with TP
2. interface is not the greatest but works fine if you pre-program the pre
sets with the usb computer link
3. external software is kind of clunky and awkward to load but works fine

I have 2 and am happy overall although 1 needs to go back now as it gives
continuous faults :(   
I understand that solid state component failures happen but it seems like
many users have had to get their units replaced at some time

I am curious what folks have experinced with these.
I bought a 4s at Toledo last year and it had a fatal (FMA's words) software
failure
within a couple months.  The new one is very temperature sensitive.  That is
it 
will go in to "cold weather" charge even when in the 74F house.  Now that
I'm going to go
electric I was looking at a 10s but I know someone that has one that appears
to be failing.
I know a couple incidents doesn't indict the whole line but I don't know
that many people that
have these for good or bad.  I'd like to hear what other folks have seen.
Thanks!
