Does not perform as expected. I do not recommend this product.
Poor technical design. Does not perform as expected. When battery reaches cut-off voltage (i.e. 10.5VDC), the relay chatters and does not cut-off the battery. The relay "chatters" as in it is switching at high speed on-off-on-off. The battery is not isolated with it reaches the desired drop off voltage. The addition of a 25Volt (1000uf) Capacitor, as suggested in the write-up, does not achieve any difference in operation. I do not recommend this product. Do not buy.
