Anticipating the need for a new leisure battery quite soon, I read the article in the current issue of the magazine (Replace your lead acid batteries with lithium ) with interest
However, after several re readings I a not much the wiser.
Questions :
Are Li-on batteries good with motor movers - article quotes inverter supplied microwaves as high demand loads, quoting an inverter powered microwave as a typical 'heavy load' This may be true off-grid, but for the majority the peak load is likely to be the motor mover. The article also suggests that the internal BMS could be limited at 50 amps 12v.
Motor movers I have used have a supply fuse rated at 100 amps, implying the peak load can be way above 50 amps. 40 amps is quoted as the normal draw for both motors running together.
Are the chargers built in to most current caravans suitable/ safe for charging lithium batteries. So far as i could see, the article indicated that they ' needed consideration' which , frankly, is not very helpful.
Finally, apart from the reduced weight what is the cost/benefit calculation given that the normal life of the lead acid leisure battery is, conservatively, 4 years and the cost in the region of £80 - 100.
I have every confidence that some reader will have the answers but I would not be adverse to saving some battery weight as i now find lead acid 110 amp hour pretty difficult to remove and reposition.
