LE300 12Vdc 28Ah / 328Wh lithium extension pack

LE300 smart battery system is a fully scalable lithium expansion solution for adding capacity to lead-acid batteries.
Existing or new 12 V lead-acid batteries can be used, including AGM or gel batteries. The LE300 is connected directly to the positive and negative terminals of the lead-acid battery.
EXTENDED LIFE
When the LE300 is connected, the lead-acid battery is maintained at full charge, while the cycle-resistant lithium battery is charged and discharged. The result is a remarkably long service life.
PLUG & PLAY
Simply connect the modules to the + and - terminals of the lead-acid battery. The existing charger is retained.
GUARANTEED POWER
The lithium modules operate independently of each other, providing a highly reliable power supply.
MODULARITY
Capacity expansion is possible even after many years. A two-module block can be converted into a four- or six-module block at any time.
INCREASING SOLAR EFFICIENCY
As soon as the lead-acid battery is around 80% full and its charging speed slows down, the LE300 takes on the surplus solar energy.
COLD RESISTANCE
Thanks to the integrated cell heating, cold temperatures are no problem for the LE300.
VIBRATION RESISTANT
The LE300 intelligent battery system is a high-quality, German-made product, resistant to vibration and shock.
LEAD BATTERY WINTERING
During winter or a longer storage period, the LE300 system can keep lead batteries fully charged.
