[NSRCA-discussion] Some more lipo fire videos

[Jay Marshall]

It may depend on the charge rate. I charge my 2100s @ 2A and they don't even
get warm and the Elite, with temp probe, has never shut down.

Vicente,
I believe with Li-Poly you would be pass the point of no return if the
batteries got warm enough to do the thermal shut off.  I may be wrong.

I am new in using LiPo.  I started with small foamy just to learn about
e-power.  I am using the Elite Charger that monitors the battery
temperature.  I bought the sensors and I am using when charging the LiPo.
The sensors shots down the charging if the temperature goes over a set
point.  My question to the experts:  Is the temperature sensor safe to
monitor LiPO charging?  I am charging only at the field on my trailer.  I
put the batteries over a ceramic title.  Now I am using 640 mah batteries
but planing to use 2100 mah in my new Brio.  After watching those tapes
looks like I need to get something better to place the batteries.  Probably
I need to install a fire place in my trailer.  Better ideas?
 
I don't think that many guys out there seat down and watch the charging
process.  We can get distracted very easy.  It is really boring to keep
looking a battery charging.  The industry has to come with better ideas to
monitor this process and do something intelligent automatically to prevent
accidents.  I think temperature sensors is a good idea.

I feel much better about being fully invested in 3 - OS 140RX's, pipes and
headers.  I'll wait till the battery technology gets a bit safer and more
idiot proof.  No doubt the future is E power, just not yet for me.  We've
had a few Lipo incidents at the local field while charging, thankfully no
major damage. It seems charging is the critical time, has anyone heard of or
seen a Lipo failure while in use or sitting unused ??

Maybe this is a good time to share these videos - if you haven't seen them
they are well worth watching. Look on the left side of the bottom of the
main page.
 
Lipos fires 1,2 & 3

I have become a bit of a lipo safety nazi lately - ever since I had my first
lipo fire a couple of months ago.
 
I have been using lipos since the early days. I'm a smart guy with a
background in electronics and all things electrical. I am known as "Electric
Larry" at our field. I teach other people how to do electrics and what NOT
to do. I'm the go-to guy in our club. In spite of all that - I had a major
lipo fire a couple of months ago that destroyed almost all my RC gear and
planes and came very close to burning down my house. It was 100% my fault. I
was doing too many things at once and had become casual/careless in my care
of lipos.  I had gone YEARS with no issues at all and had gotten complacent.
 
My equipment and charging routines are now 100% improved.
 
Be careful guys.
 
Larry
