I will add to my previous that while Li’s need to be periodically re-balanced (per Trojan’s advisory), they do not need to be fully charged upon every usage cycle...this is a most advantageous aspect...
I have no idea what Trojan means by their proprietary “contactor” device (thus, comments better reserved for Trojan...), but from my own perspective, those who opt for Li batteries would be best advised to get themselves a capable, full function ‘Lithium compatible’ SOC Meter (such as Victron’s bluetooth BMV 12)... Beyond the customary SOC display, this is the best way (in my view the ONLY* practical way) to stay informed regarding active charging status and to observe the BMS’s real-time functioning...Having said that, know that ‘post charge’ (i.e. having attained trigger voltage and brief hold duration) it normally takes an additional say 10-15 min for the BMS cell-balancing to complete it’s regime...
It’s my opinion that battery built-in type displays are rudimentary at best and inferior to a full function SOC meter.... JMO
