Installation without changing the charge controller

The lithium extension battery LE300 can simply be connected to the plus and minus pole of the existing 12 V lead-acid battery. Unlike switching to pure lithium batteries, no charging technology needs to be changed. True plug & play makes it easier and safer to expand lithium capacity to experience self-sufficiency and travel freedom anew.

True plug and play is more than just quick and easy hook-up. The LE300 automatically detects the lead-acid battery and unlocks when everything is connected correctly. The LE300 does not require any complicated settings or endless menus for operation. On top of that, the LE300 has a lot more features to offer than just a simple installation.
