Lithium Battery Installation

[JSiggy]

I've decided to uprate my Coachman caravan 12 volt system by going down the Lithium Battery route.
At present I have an AGM battery powered by a BCA 13.8 v transformer and a 120 watt Solar panel with a PWM Controller...
The Lithium battery would have a Battery Management System (BMS) within the battery.
Any recomendations or experience in this area would be appreciated

Correct solar charging routine controllers for Lithium batteries are readily available, ensuring I had a quality one of these would be one thing I would use.

Ensuring the battery chosen was engineered to charge and do so safely at low temperatures matching those your van could be exposed to.

There is a lot said about getting the correct charger for Lithium batteries, however I have an Eco worthy 280A.hr LI PO4 battery and use a Meanwell NPB 360-12-TB 2 stage charger /psu to charge it (set for lead acid) and it charges up the battery to 100% no problem , the unbuilt BMS sorts out the charging and when full stops the current to prevent overcharging ( the battery also has bluetooth and WIFI connectivity which allows you to see whats going on with the battery. Also when off grid the battery which is way too big to fit into the caravan sits at the side and the caravan inbuilt charger which is a simple 13.8V unit and it, combined with the solar regulator also charges up the battery to 100% with no problem)
