Disconnecting Battery For A Month - Issues?
- Thread starter Zagora
- Start date
Hmmm, well I imagined this simple solution would be fine:
Votronic 3065 StandBy-Charger 12V - Battery Master
But it explicitly says it’s not for a combination of lithium leisure and lead acid starter so more research is probably needed. I don’t know why having a lithium leisure battery would make a difference in this case?
@t0mb0 I saw that limitation on not mixing battery types stated. On another thread we have been discussing one from Solar Sunshine, which I’ll have a look at. Need to check though that I’m not getting a bleed from vehicle to leisure battery or it will all be going round in circles.
Battery Master - Sunshine Solar
Battery Master - Sunshine Solar
Those Battery Master type devices definitely only allow current to flow one way - they allow current to flow only when the leisure battery is over 0.5v or so above the starter.

Apologies for the thread ressurection. I have the 50W version of this solar panel on order and want to know if there is an issue with leaving it plugged into my cigarette lighter?Have a look at this 50W fold up version.
more power + a proper PWM charge controller (which your one doesnt have)

might help you out over winter months?
though agreed, nothing beats a proper multi-stage charger over winter.
The idea is for it to charge my starter battery. My starter is a Varta AGM, if that makes any difference? I have the factory leisure battery but I understand that this is not relevant until I get around to installing EHU, DC: DC, etc etc.

get a fused 12v plug for the end. (to replace the crock clips)
set controller to SLA/AGM battery type
plug it in and wait for some sun . .
look at getting a battery monitor to see what's going on with voltages and the battery . .

Battery Monitoring -- How I Done It -- Part #1 Battery monitoring is a very important part of your 12v system . . . . whether its just the vans starter battery or your leisure setup keeping an eye on the power in your battery bank will keep you from breaking down and make sure your weekends...

i recommend the BM2 units . .

[Guide] Mobile Solar Panels ? . . . - How I Did It -
Mobile Solar Panels ? . . . - How I Did It - There is loads of background to this . . . . . but for now here is a vid for you all. =] Just remember W = V*A and as a general rule a good 100W panel will give you up to 6A charge with good sun. 25w = 1.5A 50W = 3A 100w = 6A 200w = 12A 300w = 18A...

Thanks! What size fuse would I need?

the fuse it protect the cable to the solar controller . . . so 10A should do it.
to make thing easier for myself . . .
i got a pre-made - fused 12v extension cable. . . . . then just cut and joined it. ( or just screwed it onto the PWM controller)

According to the manual I found for the controller I should press & hold the only button on the unit until the 4 battery LEDs start flashing .... but they don't do that at all. No clue why.
At least the default is set to a sealed battery so hopefully it's ok. It's quite a grey day here but I can see the volts slowly creeping up (0.01V every few minutes!). Started low (11.6 I think) so I'm glad the charger arrived today ... Sorry for threadjacking by the way.
