Deye 12 V 100–200 Ah LiFePO4 Battery

The WD-G12 is a 12 V lithium building block, sold in 100 Ah and 200 Ah. Either one drops straight into a lead-acid position without the inverter needing to change, and both are meant to be combined: four in series makes a 48 V bank, ten in parallel makes a long-running 12 V one. The difference between them is capacity and what one person can carry, 11 kg against 21 kg.

True of every rating

• 12 V nominal LiFePO4, drop-in for a lead-acid battery of the same footprint
• Four in series for a 48 V bank, or up to ten in parallel for more runtime
• Continuous current matches the capacity: 100 A on the 100 Ah, 200 A on the 200 Ah
• Works with any brand of inverter, with a built-in BMS handling the protection

1.28 kWh 12V lithium battery, 100 Ah with a 200 A ten-second burst

One unit stores 1.28 kWh: 100 Ah at 12.8 V nominal, working between 11.2 and 14.6 V. It takes and gives 100 A continuously and 200 A for ten seconds, which covers the inrush of a pump or a small compressor. Deye recommends 80% depth of discharge, so plan on about 1.02 kWh per cycle from each unit, with the cells rated for 6,000 cycles. Four in series makes 51.2 V, and ten in parallel is the limit.

2.56 kWh 12 V 200 Ah lithium block for backup, caravans and boats

One block gives 200 Ah at 12.8 V and works between 11.2 and 14.6 V, so it drops into most 12 V systems built around lead-acid. It handles 200 A continuously in both directions and 300 A on a peak, which covers an inverter surge or a starter motor. At 21 kg it is light enough for one person to carry, and it stacks or stands on the floor. RS485 reports the state of charge and takes firmware updates.
