Anyone ?!

I think it's either the LM335, or possibly the LM35.

I've got an LM35 on order with a bunch of other stuff, so I'll give it a try when I get it. If it works I'll let you know.

Sam.

IMAX B6 Temperature Sensor -> LM35

Just tested the LM35 (not LM335) and it works well. Wiring diagram attached.

LM35 should be about 2USD I think. Plus cost of plug.

FYI here's an actual E-Station temperature probe with the shrinkwrap removed. Same chip, same connections...

I know this is a stupid question, but please humour me. What is the purpose of a temp sensor on a charger like this? Are you supposed to position the temp sensor on the lipo pack so the charger terminates the charge when the pack gets too hot, or is it about sensing the ambient temperature and varying the charge voltage as a result?

its normally used when charching NIMH/NICD batteries which heat up towards the end of the charge.
When charging at a high rate they can get really hot. Charger can be set to terminate charge if temp exceeds a preset.

In some cases (hotliners spring to mind) some people keep charging untill the pack hits a certain temp (as high as 80C sometimes, if remember rightly) - then immediately use the hot pack (apparently give better output on launch or something)

So it's not to do with terminating a lipo charge before 4.2V / cell if you're going to use the cells in a cold environment?

I hope I don't get yelled at for dragging this thread up.


Is this the same type of probe used by the Triton series?

I use my lipo only Cxarge charger's temp probe to charge my tx nimh pack. I set the charger to 3S and temp cutoff to 35 deg C. It works like a charm, cutting off current at exactly 35 deg C and sounding an alarm.
