Can I charge lipos with a nimh charger?

[jhautz]

Theorectiaclly during the first stage of charging a Lipo it is not really different than a conventional charger, but whe the lipo reaches it 4.2v limit the lipo charger switches to a constant voltage mode. Constantly adjusting the amount of current the lipo gets to keep the voltage at the 4.2v/cell.

The reason you shouldnt use a conentional charger is if that ever got to the 4.2v/cell the charger would just keep pumping the current into the pack and you would have a BIG problem.

I know it seems like a good idea, but it really is not! Lipos are very dangerous if not treated properly and this is just the kind of thing that can accidentally get out of hand very quickly. They are very dense power sources and need to be treated with respect to avoid problems. If you havent ever seen a lipos catch fire I sugest you do a youtube search for lipo fire and watch some video so you can understand what happens when things go wrong.



I dont mean to sound like sombodys father here, but I will never sugest doing what you are asking about and I seroiusly doubt anybody else on this forum would either.

There are some fairly cheap lipo chargers out there now days. This would also be a possible solution. http://www.slkelectronics.com/lipodapter/index.htm

If not I wouldnt do it.

OK just making sure. I figure since for that bat at 4amps it charges there for at least one hour if the bat is run down to the voltage cutoff. We run the same truck and everything so I just figured everything would be constant and 30mins would be no problem. Just for the record I understand the risk if I attempt it.
