Guidance on a possible 200ah setup?

[roooms]

I’m looking at a renogy setup for my lowered seat base as their new mini 100ah batteries are smaller than most.

Does this seem like a reasonable configuration for the price? I’d sell the free MPPT as that’s just thrown in when you spend £600.

Should I be looking at something else?

Very good price for what you're getting

 

[roooms]

That was enough to convince me. Thanks

I'm looking at doing something similar. Does all this fit under the drivers seat with any issues?

My setup is a bit unique so difficult to confirm 100% and here's why...

I have a Jennings "lowered" seat base designed to allow a swivel base to be fitted without adding height. I think this is about 30mm lower than normal. I then have some seat adapters that allow VW Tiguan (and other VAG car) seats with wider rails to be fitted. These add back some height (I think about 30 mm).

So I think I'm at about stock seat base height. With that configuration, the two Renogy core mini batteries fit upright under my seat, but there is zero spare height/clearance. The seat cross-beam that is part of the rail slider mechanism just clips the rubber terminal covers on the first battery if I'm adjusting it back and forward. I'm ok with that as the covers are rubber and I don't regularly adjust the seat once it's in position.

Also note that the dedicated MPPT was included free in the bundle and I'm not planning to use that as the DC-DC has a built-in MPPT.

Here's a picture of the way I installed everything, but I just can't guarantee they would fit in a standard base.

Where's the main battery fuses?

Love the idea of this set up rooms , does the spec of these batteries compare to say that of the fogstar drift 105ah that a lot of people go for?

It's in that mess of wiring to the left of the batteries. You can just see it in this picture. So the wiring between the starter battery and DCDC has an 80A midi fuse at each end.

I think the drift 105 has more features. Probably the drift eco 100 is comparable for features but then it's slightly bigger.

The renogy 100 core minis are 229 x 138 x 213 mm / 9.02 x 5.43 x 8.39 in.

The fogstars (both 100 and 105) are 260mm x 168mm x 209mm.

@roooms bit random but with your batteries and shunt what do you see in your renogy app?

I've just installed the renogy one core and shunt 300.

I've got a fogstar 105ah battery which works great. Thinking of getting the 200ah mini core battery from renogy but as that doesn't have BT I'm guessing I don't see that in the app as such.

Does anyone know if Core - 12V 200Ah Lithium Iron Phosphate Battery w/ Bluetooth fits under the drivers seat (I don't have anything else under there now)?



This is what I have currently. I can't quite seem to get the shunt to fully calibre the battery even when charged to 100%. The % and voltage are all showing correct throughout. Im guessing there are some settings to set somewhere?

Thinking just switching to a bigger renogy battery to just be all in.

I thought I'd considered this option and the battery was too big to fit under the seat

Yeah that's my thinking. I think the mini will but I kind of want the BT connection as well.

 

[JumpShip]

I'd need to double check the measurements but am away at the mo .

 

[soldas]

Thank you. I can check I'm just being lazy

 

[JumpShip]

Out of interest what solar do you have in place ?
Saw a flexi on the M4 yesterday that obviously made a break for freedom

 

[JumpShip]

Someone is gonna wonder why their solar isn't working...and when they check they'll see why

 

[roooms]

Mine only shows the shunt in the Renogy app as the two mini cores don’t have BT. It’s fairly limited monitoring really. Also my Renogy 40A DCDC doesn’t have BT. That seems to be a US model they sold as part of offer bundles in the UK for a while. Works fine but isn’t that clever when compared to stuff like the Victron kit.

I’m fairly certain that 200ah battery is too long for the seat base. Says it’s over 50cm in the specs which I think is too much. I don’t have the original seat bases though so not 100% sure.

 

[soldas]

Thanks @roooms yeah is a little basic but I kind of like that. With the dc-dc / mppt in one, the shunt, inverter, bus bars, 13v fuse board and isolators its pretty compact and I have it all tucked on the side of the kitchen.

I've got a 100w flexi panel but im about to swap to 200w.

Plus Jackary and the bigger battery (I do start to run out with 105ah in the darker months) and I'm finally done (in that department).

Are you 'sticking' with another flexi ?
