Applications: Starting engines, piston and turbine and to provide emergency backup power in case of alternator / generator failure.
For ground power use simply monitor the voltage (low voltage alarm available) and use a lithium balancing charger to keep internal cells even. Lithium has three times the energy density of lead acid thus a smller battery can still give the more usable watt hours than a lead acid type of equal Ah.
Keep in mind, the capacities of our Lithiums are meaured at C/1 discharge rate, not C/10 or C/20 like some others which give an inflated Ah capacity.
To maintain the state of health of your aircraft lithium battery, we recomend maintaining them every 20 hours or so by using the balancing charger to visually see the internal state of charge of cells on the display screen.
These aircraft lithium batteries ARE drop in replacements for PbA, NiCd and other lithium batteries (that you may have and found to be under powered). The aircraft charging system wont know the difference. Open circuit resting voltage 13.3V, fully charged 14.4V.
Storage / non use of plane; No maintenance charger needed.
Here’s a great primer on the different Lithium battery technologies at Battery University.
