and if you are an ebay plus member the postage is covered and an extra $5 off if you buy off their ebay store
My understanding is that this particular retailer is no longer a CTEK distributor and is clearing their existing stock.Wow ~ how can they knock them out for that...seems a superb deal.
Either way, I picked one up, not sure if I’ll use it, but couldn’t walk past at that price.My understanding is that this particular retailer is no longer a CTEK distributor and is clearing their existing stock.
I got one too.Either way, I picked one up, not sure if I’ll use it, but couldn’t walk past at that price.
Cheers, just ordered! If you use their welcome promo code (WELCOME10) on their website you get another $10 off (accounts for shipping).
Info from CTEK is definitely wrong. From my own observation, the Gren _has_ a "smart" alternator: Cruising at 100km/h, slightly accelerating => batt voltage drops to 14.1V. Foot off the pedal =>batt voltage immediately rises to 14.8...15.0V. Everybody (with a Gren, of course ;-) ) can easily test this with the Gren on-board "electric" info panel.Jean

Response from Ctek, which I think may muddy the water further.
Hello Miles,
I've asked out technicians about your question and received a response form them:
"Grenadier has no smart alternator. SMARTPASS is to recharge the Service battery, maintenance charge the starter battery and as a start assist function."
I confess to now being lost - but do have a shiny ctek branded 120 smart pass that came with the vehicle (twin battery option), a red cable unconnected, a 250se in readiness for solar etc, and 2 bus bars kindly supplied FOC by Ctek.
Am I incorrect in thinking Ineos have removed the smart alternator, for a std one? hence ctek installing white label 120’s?.
If so, then the red cable IS redundant, but I assume all other wiring to include 250 is relevant, and I can run a fridge from the 120 as ctek show in thier dwgs?.
If you're going to remove the 120 for any reason, and particularly if you are going to put a Li battery in, surely a redarc (or similar) Li 50a dcdc would be a better option that 2x 250sInfo from CTEK is definitely wrong. From my own observation, the Gren _has_ a "smart" alternator: Cruising at 100km/h, slightly accelerating => batt voltage drops to 14.1V.

I am also in contact with CTEK regarding the 120/250 combination, but have not received technically satifying information. I bought a 250 already and will install it, with 2 EFB batts I think the setup is ok & does make sense.
But: I plan to replace the aux EFB with a Li, and here, IMHO, the issues start with the Smartpass120: Having close to 15V coasting/going downhill, and having those 15V directly, without current limiting, "smartpassed" to the Li, will not be good. Either the Li BMS will turn the battery off due to overvoltage, or uncontrolled current will flow. The D250SE, which, as a true charger, features current control and voltage limiting. Having >14.2V (Li-mode) present at its output, however, it will be turned off. Being "smartpassed" anyway, it will be left inoperable.
Latest suggestion from CTEK was to get rid of the 120 and replace it with another 250, then having true controlled 40A max and safe voltage limit at 14.2V....
Yes, I also think so. I have a similar setup (Victron Isolated Charger and LionTron LiFePO4) in my VW T3 camper, mentioned that elswhere here.If you're going to remove the 120 for any reason, and particularly if you are going to put a Li battery in, surely a redarc (or similar) Li 50a dcdc would be a better option that 2x 250s
Here's a bit of data from my Victron Smartshunt, attached to the auxiliary battery and also monitoring the starter battery voltage.For people that have installed the D250SE how is it working out without the ignition cable attached ?
cheers, be interesting to see charge rates when the Aux is say 60% and car is then driven for an hour or more....When the engine is switched off the D250SE stays illuminated and appears to continue to power the auxiliary battery for a period of time before switching off and the power drops to zero:

46 AMPS I only get 9 tops I suspect something is wrong always got the charger on itHere's a bit of data from my Victron Smartshunt, attached to the auxiliary battery and also monitoring the starter battery voltage.
On engine start the voltage of starter battery jumps, as I assume the alternator kicks in and starts charging the starter battery. The auxiliary battery voltage also jumps, but is @10 seconds behind the starter battery:

The starter battery settles down to taking 46A and the auxiliary battery is taking 13.5A concurrently.

Same with me. Reconditioned and 100% charged both batteries after picking up the vehicle. SOC says close to 100% mostly, charging current is negligible (<10A). Always travel 50km+, no short range driving, strárt/stop always disabled.46 AMPS I only get 9 tops I suspect something is wrong always got the charger on it
