Victron Energy Lithium SuperPack 12,8V/20Ah (M5) Battery
Integrated BMS and safety switch
This Victron Energy Lithium SuperPack 12,8V/20Ah (M5) battery is extremely easy to install, needing no additional components.
The internal switch will disconnect the battery in case of over discharge, over charge, low or high temperature.
A lead-acid battery will fail prematurely due to sulfation:
• If it operates in deficit mode during long periods of time (i.e. if the battery is rarely, or never at all, fully charged).
• If it is left partially charged or worse, fully discharged.
A Lithium-Ion battery does not need to be fully charged. Service life even slightly improves in case of partial charge instead of a full charge. This is a major advantage of Li-ion compared to lead-acid. The SuperPack batteries will cut-off the charge or discharge current when the maximum ratings are exceeded.
In several applications (especially off-grid solar), energy efficiency can be of crucial importance. The round-trip energy efficiency (discharge from 100 % to 0 % and back to 100 % charged) of the average lead-acid battery is 80 % .
The round-trip energy efficiency of a Li-ion battery is 92 % .
The charge process of lead-acid batteries becomes particularly inefficient when the 80 % state of charge has been reached, resulting in efficiencies of 50 % or even less in solar systems where several days of reserve energy are required (battery operating in 70 % to 100 % charged state).
In contrast, a Li-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 allowed.
Use in upright position only.
