Portable stations are just expensive paperweights if your draw is decent — you'll flatten them quicker than a narrowboat toilet tank in summer.

Series on a narrowboat is asking for trouble — one dodgy panel in cloud and your voltage tanks faster than your energy levels after lock season.

Matched my two Fogstar LiFePO4s in the shepherd's hut last year — same voltage, same capacity, same manufacturing date because I'm paranoid — and the BMS absolutely hates you when you don't...

Mate, the jump from PWM to MPPT is genuinely transformative — you'll wonder why you suffered through those dodgy years.

Mounted mine upside down in the shepherd's hut because apparently I don't read instructions — still works perfectly and the irony isn't lost on me.
