Ok,,,,,,,,,,
Here ya go,,,,,,,,,,,
First,,,, I'm flying with an Eggtimer altimeter,,,,,,,,,
It's been working fantastic,,,,,, I have nothing but positive to say about it..........
The Eggtimer altimeter uses a separate battery to power the chip and the pyro outputs,,,,,,,
so it's much less likely to brownout the chip in flight,
this is a good thing,,,,,,,please don't ask me how I know..............
All Bob said is correct,,,,,but I just learned a valuable lesson to add,,,,,,
I have a computer charger for years now,,,,,
I've used it to charge everything from lead acid motorcycle batteries
to lipo's, to nicad's and nickle metal hydride,,,,,,,
it's a balancing charger, thats a must,,,,,,,it works great, I love it.....
It does from 2s thru 6s lipo
The Eggtimer uses a 2s on the pyro outputs and a 1s to power the chip,,,,,,,
My charger won't charge the 1s,,,,,,,
So here's the charger I wish I had right now,,,,,,,,
and don't forget,,,,,, I paid near $150 for my charger, and I need a 12v power supply on my bench to run it,,,,,,,,,,

This charger will run on your car batt at the field, (you probably wont have to though )
it has a built in power supply, plug it into 115V. AC,,,,,,,,
it will accomodate 1s thru 6s lipo's,,,,,,,,,,,
It will charge any battery chemistry your ever gonna need,,,,,,,
and very important it WILL save you money by keeping your batts in
good shape- it charges,, discharges,,, and cycles ,,,,,
this 2s batt I'm using on my Stratologger now,,,,

This 1s I'm using to power the chip on my Eggtimer now,,,,

These are the JST connectors the 2s battery comes with from th4e factory,,,,,,
so that is what I'm using where nessasary in my altimeter bays,,,,,,,,

When you place an order,,,,,,get everything you need in one shot,,,,,,,it'll be a while before you get it.........
And be forewarned,,,,,,,,your not going to like the shipping costs,,,,,,,,,
You can reduce them by placing the order in the USA warehouse for what they have there,,,,,,,,,
but it won't be everything,,,,,,,,,
