Lithium (LiFePo4) consumer batteries offer large energy capacity while being much smaller and lighter than lead-acid batteries. The batteries are extremely protected against deep discharge and can be recharged very quickly.
VICTRON's SuperPacks feature an integrated battery management system (BMS) and an automatic safety switch that protects against deep discharge and overheating. Therefore, they can be charged with a conventional (for LiFePo suitable) charger or solar system without any further additional components (Plug & Play).
Not suitable for high discharge currents.
Several batteries can be connected in parallel (capacity increase), series connection for voltage increase is not possible.
Lithium battery or lead-acid battery?
Conventional lead-acid or AGM batteries can only be discharged to about 60% of their capacity. So a 100 Ah lead-acid battery can in fact only provide about 60 ampere-hours (Ah) of current. In contrast, up to 90 Ah can be discharged from a 100 Ah lithium iron phosphate (LiFePo4) battery. This results in significantly lower weight and volume for comparable battery capacity. In addition, LiFePo4 batteries can be charged much faster with a high charging current, are extremely cycle-resistant, maintenance-free and durable. For consumers with high current consumption (starter,windlass, ...) most lithium batteries are not suitable.
