Lithium SuperPack 12.8V/100Ah-a (M8)

Victron Lithium SuperPack

Integrated BMS and safety switch
SuperPack batteries are extremely easy to install and require virtually no additional components; however, it is recommended to install a relay between the generator and the battery to prevent the generator from always running at maximum capacity. The internal switch disconnects the battery in case of over-discharge, overcharge, low or high temperature.

Protected against misuse
A lead-acid battery will fail prematurely due to sulfation:
• if it is used in a discharged state for long periods of time (e.g., if the battery is rarely or never fully charged).
• if it is left partially charged, or even worse, completely discharged.

A lithium-ion battery does not need to be fully charged. In fact, its service life is improved if it is partially charged rather than fully charged. This is a major advantage of a lithium-ion battery compared to a lead-acid battery. SuperPack batteries will cut off the charging or discharging current when the maximum capacities are exceeded.

Efficient
In many applications (particularly off-grid solar and/or wind power systems), energy efficiency can be of critical importance. The round-trip efficiency (discharge from 100% to 0% and back to 100% charge) of the average lead-acid battery is 80%. The corresponding figure for a lithium-ion battery is 92%. The charging process for lead-acid batteries becomes particularly inefficient when a charge level of 80% has been reached, resulting in 50% efficiency or even less in solar power systems where several days of reserve energy are required (the battery is used in a 70% to 100% charged state).
In contrast, a lithium-ion battery will still achieve 90% efficiency even under shallow discharge conditions.

Can be connected in parallel
The batteries can be connected in parallel. Series connection is not permitted.
Must only be used in an upright position.
