How to not blow up your Alternator when charging Lithium

We get a lot of questions on the charging issues with Lithuim Batteries and Victron have now done a video (with the help of Jono) and hope this helps..

Derwent6 uses a DC to DC Buck Boost that reduces charging to 25 amps. Also when the batteries are fully charged the BMS system directs those Amps to two 12 volt lead acid batteries (called dump batteries) so the alternator doesn't get too hot. So far this has been fine, but the test will be through the very cold winter months.
