Collection: Sodium Batteries - Horizon Series - Leisure

The Horizon series is the NAIONICS deep-cycle sodium line, built for leisure duty rather than starting: 12V in 50Ah, 100Ah and 200Ah and 24V in 50Ah and 100Ah, all with Bluetooth on board for monitoring from the app.

Deep cycle is what you need where the battery is discharged and recharged every day: fridge, lights, pumps, inverter. The selection criterion is energy in Wh against daily consumption, with margin so you never go below 20% remaining, plus the stated maximum discharge current.

Against lithium, sodium chemistry takes the cold and full discharges better, uses no critical raw materials and is safer when abused. Ideal for motorhomes, boats and off-grid solar systems.
