Hi all,
I have the Hummel 2400 engine and yesterday and shortley after leaving the pattern I noticed that both my MGL instruments E3 and F2 were showing my battery at 17 V then proceeded to 18 Volts all the way up to 23.4 volts before I reduced power in the pattern. After I landed I looked again and it was back down to 13.5 which is what I normally see. I do have a Lithium battery. I pulled the battery and it checked out ok. I am thinking it is the charging unit but not sure what the MGL measures the battery or how much charge is comming in. Any Thoughts?
I have had the lithium battery for 2 years and really love it so I hope it is not the battery. Thanks everyone

never heard of a battery "making" voltage or electricity. If it is not a fluke reading I would look at your charging system. A battery will only hold electricity and a fully charged battery not connected to anything should only read at max about 13.1 volts +/-. When charging it needs slightly higher to get the battery to charge. Normally 14-14.5 volts. above 16 you run the risk of burning your battery up.
