we are thinking about converting our service battery on a sailing yacht from AGM 24V 600Ah to LiPo, as they AGM batteries reached end of life.
- Is there a guide what all stuff we have to think of if we switch from AGM to LiPo on a sailing vessel?
Currently the batteries are charged from 3 sources: if shorepower or the extra 230V Generator is running they are charged a. from a Victron Skylla-i 24/100 (1+1), b. from solar via Victron MppT 100/30 or c. from the main engine, there is a very big extra 24V 120A alternator with a sterling regulator which also was able to charge the AGM batteries with 100amps (with “extra” i mean that we have two alternators, one for the starter battery, one for the service battery, completeley sepearte). It happens that all 3 sources are running in parallel.
as monitor we were using a BMV 712.
- The Skylla and the Solar chargers can be switched to Lithium. currently they are not connected, but I assume i should set up a VE Can network for them if switching to Lithium so that they communicate with each other? A Cerbo Gx should do, correct? ( I anyway was thinking about this to have all data on our garmin mfds)
- as the sterling regulator is not supporting LiPo we need some other regulator or even charger here, i was looking for LiPo DC/DC charger, but neither the buckboost nor the orion series are giving 24V 100A so I have to run some orions parallel to get a quick charge, correct? Any concrete recommendations here?
4a. I looked into the overview of BMS system and it appears to me that I need a Lynx BMS, correct?
4b. So this Lynx BMS has also relay switches to switch of the chargers that there is no overcharging happening, correct? For this I need the Cyrix-Li-Charge as relay switch extra or is it included in the lynx? depends probably an what i buy as replay to my question 3
thanks!
best, johannes
