Hello Everyone!
I bought a Lithium Magnesium Iron Phosphate Battery, 138 AH and 13.7V, to be used to power my Newport Trolling Motor. The problem is the warranty on the motor will be voided if I use a Lithium battery. The manufacturer rep said that the Lithium ion batteries outputs a constant voltage of 13.7V no matter what the load is, until of course it starts to run out of charge, and such high voltage could burn out the electric motor that is expected to be powered by a deep cycle 12V battery. I really like to use the Lithium battery because it is very lightweight and high energy density to last a very long time compared to deep cycle lead acid batteries.
The 12V electric motor is rated for at 20A continuous and short peak bursts of 30A. What's the best existing 30A product to use to protect the motor so that it won't burn from the slightly higher voltage. Where to get 12V 30A voltage regulator from 13.7 to 12V? This is a small drop but require large current. Is the buck boost controller better? Where can I buy these? Do I need to assemble a circuit for this?
This problem is becoming quite common as lithium ion batteries become more available at affordable prices. The problem is that their voltage output is constant even with load, and many electric motors aren't designed for that. Any help would be appreciated. Thanks!
