Sparkfun Adjustable LiPo Charger

I need to use the subject charger in a model rocket as an onboard charger for 400mA battery that supplies power to a Featherweight GPS Tracker unit. My question: is there a power “out” capability on your charger circuitry that I can run to the GPS tracker? I’m trying to do an in-line installation so the battery can stay installed. The order of the install would be:

LiPo 400 battery → Charger → Magnetic actuated switch → GPS Tracker.

When the GPS is not in use and “Off”, the charger would be hooked up with the USB and the battery can be charged in place.

No; if you used the ‘batt’ leads it would split the voltage between the 2 ‘outlets’ (JST connector and batt holes) - it might be better to look at powering the item separately with small batteries
