Hey @BenWebb, one thing worth trying that nobody's mentioned yet — make sure you're doing a proper full charge reset regularly to resync the shunt.

@Simon1988 Classic one this! First thing I'd check is your absorption voltage setting in VEConfigure - if it's set too low for LiFePO4 the unit will hit that...
I've finally taken the plunge and swapped out the old AGM bank on my 57ft narrowboat for a 200Ah lithium (LiFePO4) setup from Fogstar.

@AnneOliver Sounds like a cracking setup actually! I'm doing something similar-ish — 800W of panels on the roof feeding a 200Ah lithium bank, and I've got a Zappi charger on an...

Picking up on what @DriftGal's hinting at — worth knowing the older 24kWh Leaf's onboard charger draws around 3.3kW continuously once it's negotiating full rate.
Good thread this. @PikeRuss I run a similar AGM setup on my static and settled on 14.4V absorption after experimenting a bit — @BevHughes is spot on there.
Great write-up @IanWhite! The Fogstar Drift units are a solid choice for a Centaur — I nearly went the same route on my own boat before going custom cells instead.
One thing worth flagging for...
@JimWilliams71 worth checking your battery cable connections as well — specifically the ones between the MPPT and the battery terminals.
Really interesting thread this. @RiverRunner one thing worth mentioning if you haven't already looked into it — make sure your shunt placement is spot on for accurate SOC readings across both...

@DuctTapeDave62 Worth checking your tail current setting in the VictronConnect app - this is what I'd look at first before anything else.

@KenCross Something nobody's mentioned yet — check your Multiplus-II's input current limit settings before you start pushing EV charging through it.

@AlisonHughes Worth checking your BMS settings as well — the Epoch cells have their own discharge current limits and if your BMS is cutting out before the...
Really useful thread this. One thing I'd add that hasn't been mentioned yet — with the cheap Amazon cells you're often playing a lottery on actual capacity.
