Good, I can program it the way I want. Would like to see a reboot function on it though, why it this not an option? Faster functions and menus would help too. Needs to be more clear on the program name that it is using, not the generic number that it gives. On that note, would like to rename the programs also, so that I can charge different battery loads and different battery types without having to guess. It could go a long way to being better, especially for the premium price of the hardware

This app and the Lester charger connected is frustrating and overcharged our large 24V batteries after losing charge settings over time. Can't see the settings because it uses cryptic numbers instead of amp/Volts Not well thought out, intuitive or reliable. Bluetooth hangs up, needs constant reboots of the charger, requires Email sign up and won't connect at all without a battery connected Not nearly enough room here for half the problems. Whats charge "profile 22349" ? or #2

The app offers a "wizard" (both while connected to charger and offline) that steps you through a process to select the correct battery profile number. A user can also get a detailed description for each battery profile by selecting ? by each number. Please contact us at: service@lesterelectrical.com so we can help you with the issue you are seeing.

I initially had the same problem about not being able to connect to the charger via Bluetooth. If you're connecting directly to the batteries, connect your positive first. As you connect your negative, make sure the charger posts with all 3 lights on (green, yellow, red) and then turning off. Also make sure they stay that way too as you tighten the nut. If the lights come back on as you're tightening, then start over. After I did this the app worked fine for me.
