27.5.1 General: MAX Li-Ions
The MAX with lithium-ion technology provides all the benefits of modern and efficient battery technology:
 Low weight
 Short charging cycles
 Interim charging possible (each charging counts)
 High degree of energy utilisation in a charging cycle (discharge from 100 % to 0 % and recharging to
100 %). This is at 92 %
 Long operating life, approx. 2500 cycles at 80 % discharge depth
Wide operating temperature range
 Fast-charging possible (depending on charger)
The lithium iron phosphate battery has an integrated cell balancing and cell monitoring function. The
additional external battery management (BMS) monitors the following functions:
 Automatic cell balancing
 Protection of battery cell against voltage dip (under 2.5 V)
 Protection of battery cell against voltage surge (over 4.2 V) through reduction of the charging current
 Switching off system in case of excess temperature (if temperature of the battery cell rises above
50 °C).
