What this video covers

A 100Ah, 12.8V Redodo lithium iron phosphate (LiFePO4) battery powers a custom electric dinghy project.2:12 The battery features integrated Bluetooth connectivity for monitoring state-of-charge via a mobile app and includes an internal battery management system (BMS) with low-temperature charging protection that cuts off current below 5°C.2:21 Rated for a maximum continuous discharge of 100A and a peak of 500A, the unit is paired with a Yamaha MS20 saltwater-series electric outboard motor, which draws a maximum of 42A at full load.3:28 The installation uses a 20A charger, providing a 0.2C charge rate.2:47 During initial testing, the system draws 6A under partial load, with no heat buildup detected at the crimped connections or terminal bolts.11:41 The IP65-rated housing is constructed from flame-retardant plastic, measuring 26 x 17 x 21 cm.5:59 While the battery functions as a drop-in replacement, the internal BMS requires compatible charging sources to avoid potential conflicts with standard lead-acid charging profiles.4:54
