<DIV>Thanks Dave,</DIV>
<DIV> </DIV>
<DIV>Looks like we arrive to a good conclusion. We have to baby sit the charging process of any battery if we want to be 100% safe. Also, it appears base on our observations that the chances to have the problem with lithium is a little higher than older technologies. I could be wrong but that is the only reason to have the instructions in the lithium batteries. Definitively, I baby sit when I charge my electric planes batteries (lithium) and I take them out of the plane. However, I don't baby sit the rx and tx (Nicads or NiMh) and I don't take those out of the plane. I don't baby sit the laptop and cellular phones. What about cordorless phones. They are charging all time. Well , I just found that I am not 100% safe.</DIV>

<DIV>Vicente,</DIV>
<DIV> </DIV>
<DIV>For the 30 years I've been using rechargeably batteries in RC, I have had one nicad and one nimh vent and smoke - no fire, no explosion, but definitely very hot and smoldering. Certainly hot enough to have caused a fire if in a different environment. In both cases, I was close enough to smell the problem and remove the batteries from the plane without damage to anything other than the batteries (and maybe some charred/scorch marks).</DIV>
<DIV> </DIV>
<DIV>Point being, ANY battery can have a problem. The higher the energy density and larger the amount of energy stored, the greater the potential problem. And it would seem in RC applications, the more mature battery technologies are the safest for our typical use, but some would advocate never charging any battery unsupervised.</DIV>

<DIV>Here are the safety instructions for TP batteries web site: </DIV>

<DIV> </DIV>
<DIV>I could not find the safety instructions on the Duralite web site. </DIV>
<DIV> </DIV>
<DIV>Here the safety instructions from Fromeco web site:</DIV>

<DIV>The problem I have is that I don't have time to baby sit while the battery are charging. I try to do it with my small electric planes and I can not imagine babysitting all my planes while charging. Probably this is the only issue I have in regard lithium batteries. Do we really need to follow this instructions? If not, the manufactures will need to take the risk and take those instructions out from the web sites.</DIV>

<DIV><FONT face=Arial color=#000000 size=2>I had bought a few NMP 2400 mAh packs from Central last year. I don't see them on their website now though.</FONT></DIV>
<DIV><FONT face=Arial color=#000000 size=2></FONT> </DIV>
<DIV><FONT face=Arial color=#000000 size=2>I am apprehensive to go Li-Poly due to the packaging and possibility of damage and fire. The Li-Ion is in a metal can that can shield it from physical damage. Using the wrong charger on the other hand would still be an issue. </FONT></DIV>
<DIV><FONT face=Arial color=#000000 size=2></FONT> </DIV>
<DIV><FONT face=Arial color=#000000 size=2>The Li-Ion packs are lighter than a NiCad or Ni-Mh packs so you gain a weight savings and they need less maintenance than the aforementioned battery types. </FONT></DIV>
<DIV><FONT face=Arial color=#000000 size=2></FONT> </DIV>
<DIV><FONT face=Arial color=#000000 size=2>I even made a pack to replace the Ni-Mh pack in my Multiplex EVO and it is holding up well.</FONT></DIV>
