Noco NLX31 12V 120Ah is a LiFePO4 lithium service battery for boats, designed to power onboard loads (fridge, fishfinder, GPS, lights, inverter) through deep daily discharges. It is not a starting battery: it replaces the lead-acid service bank at around 60 % less weight.
Why this lithium marine battery?
- Deep-cycle service bankdaily discharges to 80 % with no capacity loss
- 60 % less weight on boardthe same energy as lead-acid in far less space
- Built-in BMS, maintenance freeprotects against overcharge, over-discharge and short circuit
Where it fits: the Noco NLX31 is one of our boat batteries and by capacity it sits among our 120Ah batteries.

NOCO NLX31 12V 120Ah 1600A dual-purpose LiFePO4 lithium battery
The NOCO NLX31 is a dual-purpose lithium iron phosphate (LiFePO4) battery that combines the power of a starting battery with the capacity of a deep-cycle battery. It provides 120 Ah (1,536 Wh), 1,600 A of starting current and 200 A of continuous discharge, in a BCI group 31 format.
It accepts up to 120 A of charging current (1C), allowing a full recharge in around one hour, and is rated for 2,000 cycles at 100% depth of discharge and 4,000 at 80%. Its BMS protects against over-charge, over-discharge, over-current, short circuit and cell imbalance, with continuous temperature monitoring.
Up to four units can be connected in series (up to 48 V) or in parallel. It weighs 14.97 kg.

Frequently asked questions
Is this a starting or a service (leisure) battery?
Dual purpose: it can start the engine and also work as a service battery, handy on boats with a single battery. On boats with two circuits the ideal is one starting battery and one service battery.
In what position can it be installed on the boat?
Being lithium, it is sealed and does not spill: it can be mounted tilted (never upside down) and copes well with vibration and wave impacts. Secure it firmly and keep the terminals away from water.
What are the measurements of the NLX31 model?
Dimensions (length × width × height) are 330×173×218 mm — also written as 330x173x218 mm — following the European DIN standard. Always measure the space in your boat before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.
