The E163 is the big pack in the E-Series line, weighing 76 kg and meant for a permanent spot on a boat. It talks to ePropulsion motors over RS485, and up to 16 units can run in parallel over CAN-Bus. The charger is sold separately, and charge time depends on whether you run one or two chargers.

Good to know
- The E-Series charger is not included, so add one to your order. Two chargers in parallel cut charge time roughly in half (about 5.4 hours on 110V versus 11 with one).
- At 76 kg this battery needs a solid, permanent mounting area, so measure your space against the 18.5 x 11.6 x 19.5 in footprint.
KayakDIY take: This is boat-sized power, far beyond what any kayak can carry, so I’d only look at it if you’re running a bigger ePropulsion outboard. For lighter kayak setups, see my best kayak battery guide.
