I was happy with doing that. I did have to charge and balance my battery a few times on the trip due to killing the battery totally first day out of Astana - stand by for story in next few days.

Overall, my experience is that its fine to take a LiFePO4 battery on a 3 month trip out in the boonies ... on the condition that you MUST take the special charger / cell balancer along with you. That decreases the advantages by increasing bulk (and cost), but its still net, a lot lighter than a lead acid battery. Note, if travelling in a group, the addition bulk and cost need only to occur once ... in a group of 5 people all with the same brand LiFePO4 batteries, only one person would need to be carrying a charger. That increases the attractiveness of the proposition.
I understood that you carry a dedicated charger for Shoray batery but if it's dead, isn't it posible to start the bike with some power cables and then let the alternator do the job ?
Adventure is not a cable channel.Freedom from the prison of pavement.
The beaten path is for beaten people.Pain is momentary.
Giving up is forever.Rest when you're dead.
