Lithium Batteries

Our LiFePO4 lithium battery line is built specifically for boaters. They have a super high maximum power draw for uses such as A/C, electric winches, bow thrusters, auto furlers, engine starting, trolling motors (see 48v for trolling). Note we can make custom batteries for you if need be. These batteries have very low to no fire risk which is much appreciated on board boats. Up to six can be run in series or parallel for larger power needs. We offer them with replaceable BMS (battery management systems) in case you go on a long offshore trip and want peace of mind - should a BMS fail a new BMS can be easily swapped in. And then they have all the usual advantages of lithium including 3000+ cycles, many many years of expected use, very fast and efficient charging (using lithiums effectively increases your solar output by 20%+ due to the charging efficiency vs lead acids and AGMs). And on that note we offer 10% off batteries with solar purchases.

What Our Customers Have To Say

  • Doug Heath - Santa Fe, NM

    Customer Service and Product

    Very pleased with the performance of the rigid solar panels purchased in 2022. Customer service also has been consistently excellent both before the sale regarding product selection and after the sale regarding installation and maintenance concerns.

  • William Roth - Kodiak, AK

    Heavy Duty Panels For The Win

    Installed 1200watts of panels on my 56' commercial fishing boat in Kodiak Alaska, with salt spray and harsh winters I hardly run my genset. Installation was a breeze with using silicone to mount them. Most the boats in my family fleet have them now and we are all saving big on the fuel bill! Couldn't be happier with the purchace.

  • Hartwell C - Bellingham, WA

    Easy Install - Great Performance

    I worked with Tom last year to design a system for my sailboat; the dialog and information was very detailed and helpful in helping determine my system needs and completing the installation. Once ordering, the kit arrived in a timely manner and very complete. The install was very straightforward and Tom provided additional information as needed. After the install I took off on a 7 month cruise of British Columbia. The system worked perfectly during my trip. I’m very happy with the equipment and support from CMP and Tom. I highly recommend !
