Single cell LiPo checker?

Question

Hi,I have a Zenoah 20 which uses a single LiPo cell (3.7v) as the ignition supply and have been looking for a checker that will indicate when the voltage drops to 3v.I found a gadget that reads individual cell voltages in multi-cell LiPo packs but it won't indicate for a single cell.Anybody know of a suitable widget that can be left connected in parallel to the cell in the aircraft to indicate the cell state?Alternatively is there an electronics guy out there who can come up with a suitable circuit to do the job? - I'm OK with soldering components etc.cheers

How about a simple VOM?

I don't know the answer. I have the Zenoah 20 and currently use a very large NiCad.  How does that Li-po work,what capacity (mah) is it?mk

Hi MK - It's a 3450maH single cell directly connected to the ignition module and works fine but it cost me about $60 in your money so I'm keen to make sure it doesn't get over discharged!cheers

BRC hobbies in the UK do a checker that is claimed to do one cell. sure where the OP is but there may be a shop selling somethingsimilar

Thanx for that - it sounds like it's what I'm looking for but I can't get the site to open at the moment - I'll keep prodding it.cheers
