It seems once again, no apples with apples comparisons, only apples with oranges and pears with grapes.

What are the key factor to consider.

The battery capacity in amp/hr and KWh

Cycle life @ the C rating.

The normal and max charge/discharge current.

The type of cells being used in the battery.

The communication with the inverter.

How many you can connect in parallel.

Working temperature.

The warranty.

Very very important, the support and availability.
