LiTime LiFePO4 24V 200Ah Group 8D Deep Cycle Lithium Battery

LiFePO4-battery 25.6 V and 200 Ah, energy 5120 Wh. The case corresponds to the BCI Group 8D size, so it takes the place of a lead-acid battery of the same format.

Weight is 38.93 kg, compared to about 140 kg for four 12 V 100 Ah lead-acids. At the same voltage, this is twice as much useful energy as at 24 V 100 A·h.

The BMS is designed for 200 A of continuous discharge, so the 5 kW inverter works without sags. The maximum charging current is 0.5C, i.e. 100 A, full charge in about 2 hours. Recommended charge voltage 29.2 V, current 40 A.

Dimensions 520 × 269 × 220 mm, M8 terminals for 8 × 16 mm screws, IP65 housing with two handles. Self-discharge no more than 3% per month, resource 4000–15000 cycles and up to 10 years of service.

Expanding the 4P2S gives a 51.2V and 800Ah system, about 41kWh. Warranty 5 years.
