Blue Smart IP 22 / Permanent Conection with Battery possible

[UliDe]

I’m using the BSC IP22 12/20(1) to charge the LiFePo4 on my boat. I’m wondering if it’s possible, to leave the charger connected to the battery all the time or if it’s necessary to use a relay to cut the connection, when no shore power is available?
Iow: Will the charger survive permanent connection if the LiFePo4 is charged via DC/DC-Charger or via solar power?
Thanks in advance for suggestions,
uli

Hi, that should not be a problem. There is a recent discussion on this topic which may prove useful to you.

Using IP22 Charger in power supply mode

Hi, I am using an IP22 12/30 to charge a 200amp LFP04 battery. It works well. However I want to leave it connected to shore power to power the fridge. The fridge draws around 4.5amps when cycled on, in a 24 hour period it will average an amp per hour. Is it safer/better to use ‘power supply’ mode when the boat is unattended or should I simply leave it in ‘charge’ mode to maintain the battery at ‘float’ level and supply intermittent power to the fridge? I don’t usually leave the battery on char…

Best of luck, Tony
