[QUOTE="Ded Driver, post: 443422, member: 12692"] Myself & a couple of people I know doing vehicle electrics upgrades &/or add-ons, I thought it relevant for people to share ideas, experience, hints, photos & anything else to do with dual battery systems. I am looking into Lead Crystal Deep Cycle batteries & finding some interesting pros & cons about them. The main 'pros' points that I like are high cycle life, deep discharge beyond 50% (they say up to 100% wont kill it) & a discharge voltage curve near to that of a lithium at half the price of lithium. The 'cons' side, whilst they are good to 60degrees they are not good in the engine bay, & they come at a premium price above std AGM .. Betta brand 100Ah $595 on this site [URL]https://leadcrystalbatteries.com.au/product/battery-6-cnfj-100/?v=6cc98ba2045f[/URL] or Pure Energy (currently on sale) [URL]https://www.pureenergybatteries.com.au/pure-energy-pb-crystal-12v-130ah-deep-cycle-lead-a[/URL] and tho you can use a normal smart charger (set to AGM), it needs to have a current output of 1/3 the rated Ah of the battery, ie the 100Ah battery needs to be hit with at least a 30A charger! The data sheet for the Betta battery can be downloaded from their website, there is a download link on the link I posted above. Here is an extract of that datasheet [IMG]https://www.prospectingaustralia.com/forum/img/member-images/12692/1538651202_betta_lcb_6-cnfj-100ah_datasheet_extract.jpg[/IMG] [/QUOTE]
