Batteries DC Power in a box
Everything has a purpose, this ethos lies at the core of our decision-making at Element 82 and batteries are no different. Cranking/Starting or high power/burst energy vs. Deep Cycle which is the term used for a discharge of energy before any recharge. That's the basis or starting point from there, capacity, expected life cycle, physical size, and layout considerations. There are so many options because batteries have so many applications.
Deep Cycle is used in house/service batteries in applications like a boat or motorhome when there is a sustained discharge from them before a recharge might occur overnight connected to mains or in a boat when the motor is started and recharge is provided via the alternator. Many brands of AGM batteries have a high power discharge capability, having said that it might only be 5-8 times its Amphour rating. So if a 100Ah battery refers to its ability to discharge 10 amps over 10 hours, it might also have a fast discharge capacity of 600 amps, referred to as 600CA (Cranking Amps). In these instances, while the battery might be classed as a deep cycle it has usable power for cranking. Numbers only get better when it's a 200Ah battery with 1200CA, you can see how this is sometimes why AGM batteries might be referred to as Dual Purpose Batteries.

Sterling Power Pro Combi S Plus Inverter Charger is a bespoke unit with a very compact footprint at only 225mm x 205mm x 230mm weighing 8.5Kg. It includes a 1600VA inverter (or as most people would prefer we say) a 1300W inverter matched with a 70A 12v charger or 35A 24v charger.
The front panel is removable for remote relocation and a 30A automatic cross over switch once mains power is detected it auto-switches to charging mode. The unit is Neutral-Earth Bonded to allow RCD's to work correctly and has an additional 5A auxiliary charging output port selectable for 12 or 24-volt output for starting battery maintenance charging.
The main chargers have 8 charge algorithms all with their own 4 stage charge profile. An option for charging only, low power saver mode and is Power Factor Corrected to account for varying AC voltage input from poor mains feeds like commonly found at marina's or campgrounds and from generators.
Technical Information:
- DC Voltage: 12V
- Nominal VA: 1600
- Nominal W: 1300
- Max Charging Current: 75A
- 5A aux charge output with selectable 12 or 24v output
