RC Flight Log: Battery Tracker

Log every RC flight in seconds and always know which LiPo pack is ready. A field-first logbook for planes, helicopters, gliders, drones and FPV quads.

LOG A FLIGHT IN TWO TAPS
• Start a field session: GPS picks your saved field and fills in local temperature and wind
• Tap the model you flew and the next charged pack is already suggested
• Use the timer or a duration chip, tap Good or Crash, save. Undo is one tap away
• Airtime, pack cycles and model counters update automatically

ALWAYS KNOW WHICH PACK IS READY
• Every pack is Charged, Used or Storage at a glance
• Batch charge: select packs, mark them Charged, cycles counted for you
• Pack sets for packs flown together, like 2×6S for a 12S heli
• Receiver and transmitter packs warn you to recharge before they go flat
• Storage reminders when packs sit charged too long
• LiPo, LiHV, LiFe, Li-ion, NiMH and NiCd, and add identical packs in one go

TRACK LIPO HEALTH
• Internal resistance (IR) tests with history for every pack
• Cycle count, purchase date and cost per pack

YOUR WHOLE HANGAR
• Planes, helis, gliders, multirotors, FPV and jets: electric, nitro, gas, turbine or unpowered

CRASHES, REPAIRS AND MAINTENANCE
