Has anyone fitted a Roamer 460ah battery?

[Bec@Fogstar]

Hi BigDean

The float voltage is 13.8V (3.4V per individual prismatic cell).

We have specialized in Li-Ion batteries for a while, which should not be left unattended whilst charging, however - this is not the case with LiFePO4. You are correct, this shouldn't be on there - it looks like a product template was used. I will get that removed.

Thanks,

Bec

Hello all,

Apologies for the misinformation I hope forum admins do not mind me posting. The spec sheet is wrong and is currently being updated as we speak. The JBD BMS has a 200A discharge, and 200A charging capability. The 200A JBD has fitted to all Fogstar Drift batteries apart from the 105Ah, which is fitted with the 100A version (charge and discharge).

The 460Ah contains EVE LF230 cells, and a 560AH containing 280 cells is due in the near future (this will be 6000 cycles @ 80% DOD - the highest possible cycle life of any 12V battery).

I have created a 15% code motorhomefun15, hopefully, that may be of some use to members here.

Once again, apologies for the mistake on the spec sheets!

Happy motoring

Bec

Hello and to the Forum.

Hi, I think it's prob worth your while to contact Jim just to make sure you are within the posting guidelines for a business!
Welcome to the Forum, I'm sure you will be able to answer more than a few questions re lithium batteries for us mere mortals !!

Bec's (Fogstar) post appears to have been deleted I think she was just trying to be helpful I hope Jim signs them up as a trade member as a 15% discount really makes them competitive.

Just had another look at their site and the BMS data has been updated. so you can charge at 200 amps max.

That’s good as Iam still undecided whether to go with Fogstar or Roamer for 2x460ah batteries. I was put off with the 50/20amp recommended charge rate but if that has now been corrected then Fogstar are back on the table, even better if we could get an additional 15% off

Thanks. In reality, when would I ever want to charge at a rate higher than 50A? (Layman's question as I don't know a lot about stuff like this, still trying to learn) I think it means it would take longer to recharge the battery, but as I am looking at using a 30A B2B, would it really be a problem if I could only charge at 30A when driving and then at 50A (max) if on EHU, especially when if I am on EHU it's likely to be around 24 hours minimum?

I assume I would then be looking at getting a separate lithium charge rated at max 50A?

The spec sheet for the Fogstar shows max charge current as 200A. The biggest difference between the 2 makes is the life cycle. Fog star are capable of much greater longevity, particularly with the 230Ah battery - 10k cycles @ 50% DOC

Thanks but I've already bought a 300ah Fogstar !
