Hi All,
I have a boat with a 12v start bank and a seperate 24v bank to power a seperate electric motor.
I want to install an Orion 12/24 dc-dc to charge the 24v bank when the engine is running.
When the vessel is in storage for long periods,
Is there anything else i need to consider if i was to use an AC charger to charge the 12v bank and then have the Orion 12/24 recharge and maintain the 24v bank?
Thanks
Sure you could do that, but you’re XS is optimized for handling high power to charge your batteries fast.
In storage everything goes slow, your charger will only deliver a fraction of the power of the alternator.
I’d get myself a small acdc charger for the 24v side.
You can try it but not sure how well it will work. You will have to play with the settings because the charger will be off if the engine voltage is not detected. Every time you go to store the battery you will need to change the start voltage to the storage voltage of the AC DC charger on the 12V. You can do this by saving the setting. Also there is only absorption and float there is no storage voltage or re-bulk etc the settings are very limited.
I do have a Projecta brand DC DC charger that I use on my boat between the lead acid starter and the AGM with a 12v charger on the start battery. This works very well in storage mode.
It also depends on your chemistry and whether you need settings for equalisation, etc. If you have lithium on the 24V, you might not even need to keep it on charge; for example, you could just disconnect the load.
