No I don’t remember what the level was but always seems to be above 90%. After my drive home yesterday which is a 86 mile run it was sitting at 97% I have used a smart charger a few times since I got the vehicle and in fact i connected mine last night so that batteries are in good condition before shipping I think maintenance charging with the smart charger helps
From my understanding it does, BUT it also connects them if the start battery is low and this will not be good for your lithium Aux battery
I'm going to use Redarc BCDC50D. Known quantity for me. Battery isolation, solar compatible, reliable.
Redarc told me to add the BCDC to the Smartpass
Are you using a lithium auxiliary battery?
Did they give an explanation why?
No, not yet, may in the future
They basically said that it doesn’t have all rhe same functionality, but no were not that specific about it.
The Redarc BCDC50 more than doubles the charging amps over the 250SE and will simultaneously charge using solar & the alternator. By keeping the Smartpass you retain the Start Assist feature & the load terminal for consumers such as the fridge etc which is then powered by the alternator while on the move. This leaves the service battery free to be charged quickly to float by the Redarc without the fridge cycling & interrupting the charging stages. You also retain the trickle charging to maintain the starter.
My concern is that the Smartpass will connect the 2 if the start battery is low, this will not end well for your lithium battery
When moving to a Lithium service battery you remove the Smartpass and just use the 250SE or Redarc and a VSR. Carry a Noco jump starter to replace start assist.
Reason you need the 250SE (or a Redarc) so it can boost the voltage. Ineos just put the base system in place, user needs to build from there depending on what consumers they run, fridge camp lights etc
Not with a smart alternator as it can throttle back the voltage to 12.xV and the Smartpass will drop out. You need the 250SE or Redarc which can boost that reduced voltage and start pulling amps from the starter causing the alternator to ramp back up. The Smartpass will then kick back in and add to the charging, depending on the service battery's state of charge.
Im conversant with smart alternators. The Redarc should negate the need for a VSR. But yes, I will be carrying a jump starter
Hi - I am also waiting to install a D250SE and would love to check how the wiring is done given we already have the 120 installed - for instance ?extra fuses required in the 250 cabling. Perhaps we should start a new thread to share the experience of adding a 250 as I am sure a few will be doing it.
This video from Ctek together with the installation diagram/instructions is helpful and explains it all. (When he talks about 6mm cable for the solar it will be 6mm2 and not 6mm automotive cable).
