The Victron Energy Smart IP43 12V 50A (1+1) output battery charger is a two-output marine-grade charger for boat owners who need to charge a house bank at a full 50A while topping up the starter battery. Current price: $98.16, down from $400.00 — a 75% discount of $301.84. Apply coupon OUTPOST12 for an extra 12% and buy online; orders over $45 ship free.
The (1+1) configuration means one main output charges your house battery bank at up to 50A. The second output is limited to approximately 4A with a slightly lower output voltage — designed to top up a starter battery, not to charge a second large bank. Connect the starter battery to the second output with appropriately fused cabling.
Yes — a large house bank on the main output and a starter battery on the limited second output. For two full-size banks, consider a two-output charger with equal ratings instead.
Compared to single-output chargers, the 1+1 design eliminates a separate starter-battery maintainer. Against other 50A marine chargers, you get Bluetooth control and Victron reliability at a clearance price.
$98.16 vs $400.00 — over $300 in savings, plus 12% more with coupon OUTPOST12 and free shipping over $45.

Boat owners who want one charger to run their house bank and keep the starter battery topped up — at a deeply discounted online price.
The second output is limited to about 4A with slightly lower voltage — it is intended to top up a starter battery while the main 50A output charges the house bank.
Run fused DC cabling from the secondary output terminals to the starter battery positive and negative; size the fuse for the ~4A current limit.
Approximately 4A, with a slightly lower output voltage than the main 50A output.
Yes — a large house bank on the main output and a starter battery on the second output. For two large banks, a charger with two equal-rated outputs is a better alternative.

Batteries were badly sulfated after a neglected season. Ran the recondition mode over a weekend and capacity is visibly restored, plus the adaptive charging keeps them topped properly now. This charger earned its price back in one save.
Fast charging. Bluetooth app is excellent. Quiet and cool. Buy it.
The (1+1) output configuration charges my house bank and starter bank simultaneously and automatically compensates for voltage drop. Installation was easy but make sure your AC wiring is adequately sized for 50A. Very happy after two months aboard.
Upgraded from a 20A charger and the difference is night and day. Generator run time for charging dropped by more than half. The VictronConnect app gives full visibility without touching the unit.
Charging performance is genuinely excellent and the Bluetooth control is convenient. But at high output the fan is noticeable in a quiet marina at night. Above 30 amps I can hear it in the cabin. Something to consider if your berths are close.
My last Victron charger lasted 14 seasons on my sailboat before I donated the boat. Bought this for the new one without hesitation. Build quality is unchanged, thick aluminum case, tidy terminals, sensible manuals.
House bank at 50A while the starter gets its own dedicated output, all managed automatically. DVCC integration with my solar charger means the whole system cooperates. Best charging setup I've owned.
Excellent charger overall, fast, efficient, well built. The Bluetooth range is a bit limited, so I have to be within about 15 feet to adjust settings. Once configured, it runs itself anyway.
Barely warm even at full output and efficiency is clearly better than my old unit judging by the electric bill at the marina. Setup through the app was painless. Exactly the upgrade I wanted.
Installed in a commercial workboat fleet, three units so far, zero failures in a year of hard use. Auto voltage sensing handles different shore power sources without a hitch. We buy Victron for a reason.
