• Please read this description before purchasing any battery. 
• My Natural Pond recognizes the need to have solar pumps continue running when there is limited or no sun.  Providing this facility for our powerful range of solar pumps demands some trade-offs to keep the costs reasonable and the performance acceptable. These lithium batteries meets this need by lowering the pump speed by 20% and the max. head from 10 to 6 feet. In return for this performance degradation the battery can provide up to seven hours of continuous running after the sun goes down.  The battery can only charge up when there is sunshine.  The battery may need 1-2 hours of sunshine on a sunny day to charge up and power the pump.
• Please note there can be occasions where bad weather extends for many days and neither the pump or battery will not work during this time.  If you have any questions at all about this battery, please call us - 760-716-5542.  It is a well-made, weather proof, heavy duty product that when correctly used can provide extra pump run time.

• The small battery can only work with the MNP SP50,
• The larger battery works with all our twin panel solar pumps.
• No battery can work with the SP25.
