12,8 V/100 Ah NG akkumulátor

This Victron Energy battery uses Lithium Iron Phosphate (LiFePO₄ or LFP) technology, known for its durability, safety, and efficiency.

The Victron Energy 12.8V/100Ah NG battery has a nominal voltage of 12.8V and a nominal capacity of 100 Ah at 25 °C.

This battery can store a nominal energy of 1280 Wh (Watt-hours) at 25 °C.

The battery lifespan is excellent and varies depending on the depth of discharge (DoD):

2500 cycles at 80% depth of discharge (DoD)
3000 cycles at 70% depth of discharge (DoD)
5000 cycles at 50% depth of discharge (DoD)

This battery has a very low self-discharge rate, with a maximum of 2% of capacity per month at 25 °C. This contributes to its overall performance and longevity.

Lithium Iron Phosphate (LiFePO₄) batteries offer several significant advantages:

Extended lifespan: They support a high number of charge/discharge cycles.High efficiency: A round-trip efficiency of 92% means less energy loss.Improved safety: Less prone to fire or explosion risks compared to other lithium chemistries.Reduced weight: Lighter than lead-acid batteries of equivalent capacity.Stable performance: Maintains a more constant output voltage during discharge.

The dimensions of this battery are 235 mm (height) x 197 mm (width) x 160 mm (depth). Its estimated weight is 9 kg.

The battery can support a maximum continuous discharge current of 100 A (1C) and a maximum continuous charge current of 100 A (1C).

Yes, an external Battery Management System (BMS) is mandatory and must be purchased separately. It is essential for cell monitoring, balancing, and battery protection.

Several Victron Energy BMS models are compatible with this NG battery, including the Lynx Smart BMS NG 500 A/1000 A, the smallBMS NG, and the VE.Bus BMS NG. The BMS manages and protects the battery.

Yes, these batteries can be connected in series, parallel, or series/parallel to create battery banks suitable for 12V, 24V, or 48V systems.

You can connect a maximum of 50 batteries for systems configured at 12V or 24V. For 48V systems, the maximum number is 25 batteries.

The battery comes with mounting brackets to simplify installation and ensure optimal securing against sliding and tipping. It can also be placed on its side.

For discharging, the battery can operate between -20 °C and +50 °C. For charging, the temperature range is +5 °C to +50 °C. Charging or discharging the battery outside these ranges can severely damage it or reduce its lifespan.

The battery power connection is made via M8 type terminals, which include threaded inserts and bolts.

The following precautions are mandatory:

Wear safety glasses and protective clothing.Use insulated tools.Avoid wearing metallic objects (watches, bracelets).Do not place metallic objects or tools on the battery.Avoid short circuits, deep discharges, and excessive charge or discharge currents.Do not open or disassemble the battery.Handle the battery with care due to its weight and sensitivity to mechanical shock.

Yes, it is recommended to perform an initial charge of the battery before its first use. This ensures that all cells are balanced and the battery is ready to operate optimally.

The balancing and cell monitoring cables can be connected in a chain (daisy-chain). They use M8 circular male and female connectors with high-speed digital communication. M8 extension cables are available separately.

To ensure the longevity and optimal performance of your battery, it is crucial to follow these conditions:

Use only a Victron Energy BMS NG approved for the battery.Avoid overcharging or deep discharging, as this can severely damage the battery.Respect the charge temperature range (+5 °C to +50 °C) and discharge temperature range (-20 °C to +50 °C).Do not use a damaged battery.Failure to comply with these conditions may compromise battery safety and lifespan.

For transport, the battery must be:

In its original packaging or equivalent. Transported in an upright position. Cartons or crates must bear an approved warning label. It falls under UN3480, Class 9, Packing Group II and must be transported in compliance with regulations (P903 for land and sea transport, P965 for air transport).
