I am upgrading my sailboat to Li Batteries
, primarily to get more efficient charging
and I have a number of configuration questions that I would very much appreciate help with.
system configuration is as follows:
4 x Lifeline GPL-4CT 220Ah 6v house batteries in series parallel providing 440Ah at 12v.
1 x 12v AGM
with serpentine belt. Balmar
Max Charge MC-612 regulator
400w of solar panels
with Morningstar MPPT40 controller.
Xantrex Digital Echo Charge charging the starter battery
Xantrex battery monitor
Here are my questions:
1. Both my solar charger
(Morningstar MPPT40) and my alternator regulator
(Balmar 612) are highly configurable so I am assuming that I will be able to set them up for Li batteries. Is this correct?
2. The Xantrex battery monitor
for my AGMs is fairly configurable but presumably designed for lead acid battery discharge profiles. Can that be set up to correctly monitor Li batteries charge level? If not, what is the alternative?
3. I would like to keep the AGM
starter battery but I assume that the echo charge is not going to work
for different battery types. How else can I deal with this?
4. I currently have 440ah of AGM batteries. Typically they only drop to around 70-80%. In exceptional circumstances they have got down to 50%. I am assuming that with deeper discharge capability and much more efficient charging 300ah of Li batteries will suffice. Is that assessment reasonable?
5. I'm looking at Battle Born 100Ah batteries. Does anyone have any good or bad experience with them?
Thanks for your help!
