Compatibility
The E100 is suitable for 48 V systems. According to ePropulsion, two E100 batteries can be connected in series for a compatible 96 V system. With this series connection, simultaneous parallel connection is not permitted. The E163 does not support series connection. The right choice depends on the motor, the desired range, and the installation. Therefore, please check which configuration your system requires before ordering.
E163 generations: the E163 version offered has article number EB-0163-00. This may not be connected in parallel to the newer E163 with article number EB-0163-01. When expanding an existing battery bank, check the article number of the batteries already present.
Good to know
A battery charger, cabling, and other installation components are not included. Choose the capacity that suits your propulsion system and match the connection to the system specifications.
