Just bought one of these for my 5kWh LiFePO4 system: Victron Smart Shunt
Endless hours of twiddling lie ahead :)

Interesting. Never knew they existed. If you are interested in expanding your battery bank there are a couple of great LiFePO4 deals going. I just bought a 100AH Lithium for effectively about $159. Deal for Voltx 100AH Lithium Priced at $289 delivered. Gets good reviews. Cashback deal (expires midnight) and rewards points drops it to $159.
Another deal via ebay for 100AH and 200AH also listed.

Thanks for that info.
As I have created my battery from 8 x 3V6, 200Ah cells and an external battery management system (BMS) it can only be enlarged by putting 8 similar cells in parallel and that would have its issues! :)
Be aware that not all 12V lithium batteries (as opposed to cells) can be put in series to create 24V and even putting two in parallel may have issues due to conflict between the BMS' - check *very* carefully with the suppliers if this is what you wish to do.
My 5kWh capability should be adequate for me in all reasonable circumstances and, if necessary, I do have a Honda EU22i generator.
I'll do a write-up about my system shortly, it's a little unconventional but would suit many I think and is much more flexible than simply staying with 12V but changing to lithium batteries.

Thanks, the VoltX website says up to 6 in parallel or serial. Really quite surprising.
I have bought two. I am thinking of using one with an old inflatable dinghy and Watersnake. If I get bored with that it will go into the van as a parallel connection. I have managed fine with a single 120AH AGM, but 200 AH would give peace of mind. Hmmm where to get my bum wet on the next trip ....
