🌟 PROLOGUE – THE HEART UNDER THE DRIVER’S SEAT

Hidden away under Vanilla’s driver’s seat šŸŖ‘ — like a dragon guarding gold — lives the Exide EZ850 100Ah AGM leisure battery šŸ¦¾šŸ”‹.It’s the power plant for every comfort, gadget, and night of warmth you enjoy. Without it? You’d have cold tea, warm milk, and dark evenings.

This one block of chemistry powers:

āœ… Fridge šŸ„›šŸ„¶āœ… Lights šŸ’”āœØāœ… Webasto šŸ”„ā„ļøāœ… Sonos šŸŽ¶āœ… Drone charging šŸššŸ“øāœ… Movie nights šŸŽ„šŸæ

The battery is kept topped up not by luck but by three well-drilled butlers who never sleep.

šŸ§‘ā€šŸ’¼ CHAPTER 1 – THE BUTLERS OF POWER

ā˜€ļø Solar Butler – ā€œSunny Jimā€

  • Eco-Worthy EW1906-30A controller + XINGCO PV-XC8.05 120W panel.

  • Loves summer ā˜€ļø, struggles in deep winter ā„ļø.

  • Mounted on pop-top for stealth and maximum exposure.

🚚 Driving Butler – ā€œVinnie Victronā€

  • Victron Orion Smart 12/12–30A DC-DC charger.

  • Pulls up to 30A from alternator.

  • Makes short drives into charging sessions.

šŸ”Œ Hook-Up Butler – ā€œSargent Charlesā€

  • Sargent EC155 mains charger.

  • Floats battery at 13.5V.

  • Ideal for storage, festivals, or full-power nights.

šŸ’” All three match their voltage settings exactly:

  • Absorb: 14.4V / 2h

  • Float: 13.5V

  • Equalisation: OFF 🚫

This prevents ā€œcharger fightsā€ āš”ļø.

ā˜€ļø CHAPTER 2 – SOLAR BUTLER IN DEPTH

  • 120W monocrystalline, IP67, wired with 4mm² cable.

  • Controller boosts at 14.4V, floats at 13.5V.

  • Summer: 7–8A peak, 35–45Ah/day.

  • Winter: 1–3A peak, maintenance only.

Example:In July, battery floats by lunch, SOC stays near 100% until night.

🚚 CHAPTER 3 – DRIVING BUTLER IN DEPTH

  • Victron Orion Smart 12/12–30A.

  • Bulk: 14.4V until ~1–2A tail current.

  • Float: 13.5V.

  • 75% SOC → 100% in ~1h.

With solar assist, this drops to ~45 mins.

šŸ”Œ CHAPTER 4 – HOOK-UP BUTLER IN DEPTH

  • Sargent EC155 keeps things civilised.

  • Mains in → battery floats at 13.5V.

  • Keeps battery spa-fresh during long stays.

šŸ›”ļø CHAPTER 5 – THE DEFENCE SYSTEMS

  • Overvoltage: 14.6V

  • Low voltage cut: 11.0V (winter: 11.5V)

  • Temp comp: –30mV/°C

  • SmartShunt logs every amp and volt

šŸŒ¦ļø CHAPTER 6 – SEASONAL STRATEGIES

ā˜€ļø Summer: Solar reigns. Orion only for cloud cover.šŸ‚ Autumn: Mix of Orion and solar.ā„ļø Winter: Orion + hook-up dominate.🌸 Spring: Like autumn but sunnier.

šŸ“ˆ CHAPTER 7 – POWER FLOW MAP

[SOLAR ā˜€ļø] ---> [Eco-Worthy] ---> [BATTERY šŸ”‹ under driver’s seat]
[ALTERNATOR 🚚] ---> [Orion ⚔] --------↑
[HOOK-UP šŸ”Œ] ---> [Sargent šŸØ] ---------↑

🧪 CHAPTER 8 – AGM MASTERCLASS

AGM = Absorbent Glass Mat — electrolyte in fibreglass mats.Pros: fast charge, spill-proof.Cons: hates deep discharge, hates overcharge.

Charging: Bulk → Absorb → Float.Sulfation = battery-killer if left low.

šŸ“… CHAPTER 9 – TRIP SCENARIOS

NC500 – September: SOC never below 90%.3 days wild: SOC from 100% → 26%, cut-off on day 3.Winter fest: Webasto drops SOC 30% overnight, Orion fixes in 1.5h.

šŸ’” CHAPTER 11 – LIFE EXTENSION

  • Stay above 50% SOC.

  • Match voltages across chargers.

  • Fully recharge weekly.

šŸ““ CHAPTER 12 – 7-DAY DIARY

Mon: Solar fills by 11am.Tue: Cloudy, Orion tops up.Wed: Hook-up day.Thu: Solar to 85%.Fri: Festival, Orion rescue.Sat: Solar float by 1pm.Sun: Long drive, full by lunch.

3ļøāƒ£ CHARGER CONFLICT AVOIDANCE

All chargers: Absorb 14.4V, Float 13.5V, Equalisation OFF.

4ļøāƒ£ EXTREME WEATHER MODES

ā˜€ļø Heatwave: +20% fridge draw, +30% solar.ā„ļø Winter: +10Ah heating, –70% solar.

5ļøāƒ£ SOC TRACKING TIPS

  • SOC > voltage for accuracy.

  • Reset Ah counter after 100% charge.

6ļøāƒ£ OH NO SCENARIOS

Fridge on for 3 days: SOC 0%, possible sulfation.Forgot Orion on NC500: SOC 30%, fixed with 2h drive.

7ļøāƒ£ SUMMARY

Three butlers, matched voltages, driver’s seat battery location, SmartShunt vigilance = forever powered.

If you want, John, I can add custom illustrated charts showing your daily SOC flow over different trip types so the Note looks like a real NASA battery mission brief.Do you want me to add those graphics next so this thing is the ultimate visual guide?
