Been keeping an eye on EG4 gear for a while now — they seem popular Stateside but I rarely see them come up in UK conversations.
@MrBodge65 bang on with the Orion-Tr, got one in my van and it's night and day vs the old relay setup.
@RetiredPlumber what lithium chemistry are you running? Makes a big difference to absorption voltage settings.
With LiFePO4 (which most of us are on) you generally want to keep absorption short —...
@GafferTapeKing19 had a basic PWM controller on my first van build and honestly regretted it within a month.
Interesting kit but this listing's a bit of a head-scratcher for anyone on this side of the pond — Sharon, MA is Massachusetts, so obviously not much use for most of us here unless you've got a...
Had this exact issue on my van build last summer. Victron 100/30 was hitting float after barely 2 hours on a decent sunny day — batteries nowhere near full.
Turned out my absorption voltage was...
@BurnGlen had the exact same issue in my van last winter. Short runs were barely tickling the battery.
What sorted it for me was fitting a DC-DC charger (B2B) rather than relying on a split charge...
Anyone else had to mount their Lynx Shunt in an unconventional orientation due to space constraints?
Running into this in my van build at the moment.
Same here — standing charge is what finally broke me. Running my van conversion full time now and the Fogstar lithiums have been solid.
Good point from both above but don't overlook the shore power input current limit setting in VictronConnect — seen this catch people out loads of times in van builds.
@PanelHarry done both in my van builds — 24v first, regretted it when I scaled up. 48v means thinner cable runs which matters a lot on a narrowboat where you're routing through tight spaces.

Had this on my motorhome build — worth checking if it's dropping BT specifically during bulk charge when the active balancer is working hardest.
@CotswoldNomad 😂 truth right there
Got a similar setup in the van — Fogstar 200Ah behind a Victron MultiPlus and I keep a Kipor 2000 strapped under the bed for exactly this scenario.
Mate, the key issue is the charger's minimum operating current. Mine's set to about 16A, so with a small genset you're running it way below its sweet spot.
