Roamer Lithium LiFePO4 Seatbase battery

A full discharge down to zero % ?
Ideally yea. This isn’t always practical if your living in the van so simply charging until it reaches float stage is ok as this resets both Victron and BMS shunt SoC readings.

Aswell as % state of charge, the internal shunt calibrates itself to total Ah capacity so after you take it all the way down to 0% and charge to 100% then it’ll show capacity as something like 202.8Ah. This total Ah capacity is affected by other factors like temp and charge rate but it’s still good that it is constantly trying to correct itself.
 
Just wish I could buy one here in Spain. God I hate Brexit..........
We can now ship to Europe via UPS on a tracked service :) You can buy through the website as normal, just select Mainland Europe as the delivery option. There is a £150 delivery charge to cover the extra shipping fees and admin but that is a flat fee regardless of number of batteries, or the model purchased. We include UK VAT in the purchase price so will refund this after ordering (otherwise you'll end up paying this twice!).

Thanks for the offer, but we will wait until next year when we visit UK and come see you and buy direct.
 
Just to follow up from Steve.

I checked this morning at 530am and see it was live.....

Enjoy. Just back from 7 days away and even after using heater, induction hub, computer, fridge etc etc had no problems as the sun charged it enough each day. So long EHU hello LifePO4.
Induction hob, which one?
 
Induction hob, which one?
I have a DOMETIC SINEPOWER MSI 1812 fitted:

This connects to a
H-Tronic switching station MPC1000 1114530 controller. Allows me to have all 240volt sockets live in the van both on EHU and inverter.

Any induction hob will work, providing you do not go over inverter max power. In my case 1800w or 3900W peak. The one I have is a Spanish make: Cecotec Full Crystal Portable Induction Hob. 2000 W, Touch Control, 10 Power levels. In the UK I would recommend a Tefal IH201840 Everyday Induction Hob, Black.

Cooking an evening meal I would draw between 6amps and 65amps max as the hub kicked in and out, total time meal for two (main, water boil for brew and washing up) about 12 minutes and battery went from 99% to 83%. Used in the morning for boiling water for wash and brew another 20amps, however after driving to next location (35minute drive) and afternoon sun was back to 100% charge. Love LiFePO4......
NOTE: Inverter is switched off when not in use. All inverters draw 2amps or more when left on........

I'll be installing ours soon into the van.. ....

Finalising some testing ... Then dropping it in.

:mexican wave:
 
I'll be starting on my install shortly just waiting on some bits and pieces to get going. Have tigged this up today in preparation. Anyone else feel like they could just use that bit more room in their seat base ?

Got a few pics for us please?

Here are some screenshots to show how I went about securing my Roamer.

The front and back of the battery was firmly wedged into place by the seatbase and front panel I built to hold my fuses.

To strap it down I bought a couple of wide L brackets from B&Q and bolted them to the base. Then from those I can either use a strap or traditional battery clamp. I haven’t finished yet so open to alternative options and suggestions.

Redarc BCDC50D . . . Nice.

i need to get mine back in again . . .cracking little charger with big power.

:mexican wave:
 
Looking at the space that takes up I will definately need my seat base extension.
Think there's a size difference between the 1st and 2nd gen batterys not sure how much though.
