Description
The smaller model weighs about 10.5 kg and the larger one under 23.5 kg, far lighter than a lead battery of the same energy, which counts on a boat or in a motorhome. Lithium iron phosphate chemistry lasts 3000 cycles or more and tolerates deep discharge, where lead loses capacity quickly. The IP65 case lets the battery sit in a locker, an underfloor bay or an outdoor security cabinet. AR1.2 connects up to 4 in series and up to 4 in parallel, taking a system from 12 to 48 V. AR2.5 accepts 2 in series and 4 in parallel, so two units also make 48 V. Before swapping, check that the charger or controller has a LiFePO4 profile, otherwise the battery will not reach full charge.
How to choose
Pick by the voltage of the old battery. A 12 V lead-acid unit is replaced with AR1.2, a 24 V one with AR2.5, and capacity is added by paralleling. For a house with a 48 V inverter and tens of kilowatt-hours of reserve, STACK100 or the standalone AquaVolt-LV at 5.12 kWh makes more sense than a bank of these blocks.

FAQ
Can AR1.2 replace a 12 V lead-acid battery?
Yes, that is what the model is made for. Just switch the charger to a LiFePO4 profile.
How much do AR1.2 and AR2.5 weigh?
AR1.2 weighs about 10.5 kg, AR2.5 under 23.5 kg.
How many AR1.2 batteries can be connected in series?
Up to 4 in series and up to 4 in parallel. AR2.5 accepts 2 in series and 4 in parallel.
What cycle life and ingress rating do the AR batteries have?
Cycle life is 3000 or more, and the IP65 case handles dust and splashes.
