Lithium SuperPack 25.6V/50Ah from Victron Energy

Integrated BMS and safety switch

The SuperPack batteries are extremely easy to install and no additional components are required.
The internal switch disconnects the batteries in case of deep discharge, overcharging or excessive temperature.

Protected against improper use

A lead-acid battery will fail prematurely due to sulfation in the following cases:

• If it is operated for a long time in an insufficiently charged state (e.g. the battery is rarely or never fully charged).
• If it is left in a partially discharged or worse, completely discharged state.

A lithium-ion battery doesn't need to be fully charged. Its operating life is even slightly increased if the battery is partially charged rather than fully charged. This is a significant advantage of lithium-ion batteries over lead-acid batteries.

The SuperPack batteries interrupt the charging or discharging current if the maximum nominal values ​​are exceeded.

Efficient

In many applications (especially in off-grid solar systems), the energy efficiency can be of crucial importance.

The energy efficiency of a charging cycle (discharging from 100% to 0% and recharging to 100%) of an average lead-acid battery is approximately 80%. In contrast, the energy efficiency of a charging cycle of a lithium-ion battery is 92%.

The charging process of a lead-acid battery becomes particularly inefficient when the 80% state of charge mark is reached. This results in energy utilization rates of only 50%. For solar systems, this value is even lower, as they require energy reserves for several days (the battery is operating at a state of charge between 70% and 100%). A lithium-ion battery, on the other hand, still achieves an energy utilization rate of 90%, even when it is in a shallow state of discharge.

Can be connected in parallel

The batteries can be connected in parallel. Series connection is not permitted.
Use only in upright position.
