I wonder if Victron would consider developing a dual-purpose lithium battery?
Most lithium batteries of circa 75-125Ah are deep-cycle only, with limited peak discharge currents that prohibit their use for starting engines.
There are now some batteries on the the market with dual-purpose capability, and with CCA’s much higher than their lead acid counterparts.
Take for example the Antigravity AG-H7-80-RS, this 80Ah battery has a CCA of 2000 amps! It also has a feature they call ‘RE-START’. The BMS puts the battery to sleep when it’s reached a point of discharge, retaining enough in reserve to start your engine. The feature is activated by a remote fob, or a button on the battery. This could effectively eliminate the requirement for a separate start battery in some applications, removing the associated complexity.
There’s also a 100Ah battery from RELiON, which has a peak discharge current of 800A.
I would love to see a similar Victron product :)
