A High Density LiFePO4 Battery for Electric Dinghy Motors

We  recently designed a 48V 60 Ah LiFePO4 battery for small electric outboard motors like the ePropulsion Spirit and Navy series that will easily fit under a dinghy seat or fit against the transom under the motor.  We have tested this battery with various ePropulsion motors are impressed with the ease of installation and the hours of operation between charges.  A cable can be ordered from ePropulsion to connect the CMPower battery to the unit.  The CMP Bluetooth app is handy for knowing the state-of-charge, amps being used to charge or discharge, time to full charge or discharge and much more.  CMP offers an easy to use 52V shore power charger and a 12 -52V DC-DC charger.  Contact CMP for more details.  248 705 8337

We converted from a 9.9 Mercury outboard and used the Navy 3.0 (6 Hp) on a seven week cruise on the Great Lakes.  Charging was very convenient for us as the dingy is on the roof of our tug when underway.  When underway, we simply plug the charger into the boat's 110 AC and the battery was always fully charged when we reached our next anchorage.  We have a 12-52V DC-DC charger onboard that also works well.
