De Voltium Energy LiFePO4 Smart Battery 12,8 V 40 Ah is een hoogwaardige lithium-ijzerfosfaat (LiFePO₄) accu met slimme functies en een integraal Battery Management System (BMS). Deze accu is ontworpen voor cyclische toepassingen en biedt een veilige, duurzame en efficiënte energieopslagoplossing voor uiteenlopende systemen zoals recreatievoertuigen, boten, visuitrusting of off-grid energieopstellingen. 

Door gebruik van LiFePO₄-technologie onderscheidt deze accu zich door een lange levensduur, hoge veiligheidsmarges en lagere zelfontlading vergeleken met traditionele loodzuur-accu’s. 

🛠️ Technologie & interne systemen
🔬 LiFePO₄-cellentechnologie

De accu gebruikt LiFePO₄-cellen (lithium-ijzerfosfaat), één van de veiligste lithiumchemieën, met thermische stabiliteit en hoge energie-efficiëntie.

LiFePO₄ biedt een stabiele spanning gedurende de ontlaadcyclus, met laag risico op thermische runaway en een lange gebruikslevensduur. 

🧠 Smart BMS (Battery Management System)

De slimme interne BMS biedt uitgebreide bescherming en monitoring:

Celbalancering voor een gelijkmatige lading over alle cellen.

Temperatuurbeveiliging om schade door oververhitting te voorkomen.

Over- en diepontladingsbeveiliging, wat de levensduur drastisch verlengt.

Kortsluit- en overspanningsbeveiliging.

Bluetooth®-monitoring via de Voltium-app, waarmee je realtime statusinformatie kunt uitlezen, zoals spanning, capaciteit, temperatuur, aantal cycli, alarmgeschiedenis en zelfs individuele celspanningen (in PRO-modus). 

Deze functies maken de accu veilig, betrouwbaar en eenvoudig inzichtelijk in gebruik.

🔁 Levensduur & prestaties

Een van de krachtigste eigenschappen van deze accu:

> 3000 cycli bij volledige ontlading (100 % DOD) bij 1C.

> 6000 cycli bij 100 % DOD bij 0,2C.

Dat is tot 10× meer dan veel traditionele loodzuur-accu’s, wat deze LiFePO₄ accu zeer geschikt maakt voor langetermijn-cyclisch gebruik. 

🔄 Serie & parallel koppeling

Je kunt deze accu’s eenvoudig uitbreiden:

Tot 4 accu’s in serie (voor hogere systeemspanning).

Tot 4 accu’s parallel (voor meer capaciteit).

Voor seriële configuraties raadt Voltium aan om een Battery Equalizer te gebruiken om celbalans te behouden. 

📱 Slimme functies & monitoring

Dankzij de ingebouwde Bluetooth®-communicatie met de Voltium-app kun je de batterijstatus in realtime volgen:

✅ Huidige capaciteit en SoC
✅ Totale spanning
✅ Aantal cycli
✅ Temperatuurwaarden
✅ Alarmgeschiedenis
✅ Spanning van individuele cellen (in PRO-modus) 

Deze monitoring maakt het eenvoudiger problemen te voorkomen en de accu optimaal te gebruiken. 

🔧 Toepassingen

De Voltium LiFePO4 Smart Battery 12,8 V 40 Ah is uitermate geschikt voor:

Recreatie & outdoor gebruik (zoals karpervissen, campers, caravans) 
Marine & watersporttoepassingen 
Mobiele energievoorziening / events 
Medische of industriële toepassingen met cyclische belasting 
Off-grid zonnestroom systemen

Keeps me organized, and cords hidden
I recently purchased the Oxford Cable Management Boxes, 3 Pack (Small, Medium, Large) with 15 Cable Ties, and I’m thrilled with how they’ve transformed my home office setup. This set is a fantastic solution for anyone looking to tame messy cords and create a clean, organized space. The three different sizes (small: 4.5"W x 9.3"L x 4.7"H, medium: 5.3"W x 12.6"L x 5.1"H, large: 6.2"W x 15.9"L x 5.4"H) are perfect for handling a variety of devices, from small phone chargers to large power strips. I used the large box to neatly conceal my surge protector and its tangle of cords, while the medium and small boxes worked wonders for my desk’s USB hubs and laptop charger. The boxes are made of sturdy, heat- and impact-resistant ABS plastic, which feels durable and gives me confidence they’ll last. What I love most is the thoughtful design. Each box has a pressure-fitted lid that’s easy to open and close, plus two cutouts for routing cables. The included cable ties—6 hook-and-loop, 6 silicone, and 3 twist ties—are a great bonus. The colorful hook-and-loop ties (blue, red, green, yellow, black, white) add a fun touch, while the silicone and twist ties are super practical for securing cords of different thicknesses. These ties made it easy to bundle everything neatly before tucking it into the boxes. The white finish blends seamlessly with my decor, giving my workspace a sleek, professional look. The boxes also have small circle feet on the bottom, which prevent slipping and add a nice touch of stability. I’ve noticed a huge reduction in visual clutter, and it’s reassuring to know my cables are safely contained, reducing tripping hazards and keeping my curious cat away from the wires. Installation was a breeze—less than 15 minutes to organize everything. The boxes are versatile enough for various settings, whether it’s a desk, entertainment center, or gaming setup. My only wish is that they included a few more cable ties, but the 15 provided were sufficient for my needs. Overall, the Oxford Cable Management Boxes have exceeded my expectations. They’re practical, stylish, and effective at keeping cords under control. If you’re tired of cable chaos, this set is a must-have! Highly recommend.

Makes everything look so much clean
got these mostly to deal with all the random cords around the house, and they made a bigger difference than I expected. They’re simple, but they actually do what they’re supposed to. Once everything is tucked inside, it instantly makes the area look way more organized and less cluttered. I’ve been using them for things like power strips and extra cords, and they hide everything really well. They’re lightweight but still feel sturdy enough, and the lids stay on without being annoying to open. Pros: Really helps clean up the look of messy cords Easy to use, no setup needed Simple design that blends in Cons: Not huge, so larger power strips can be a tight fit Plastic isn’t super thick Overall I’d definitely recommend these if you’re trying to make a space look cleaner without doing anything complicated.

Great Space Saver!
I purchased these for our family room charging hub and honestly wish I had known about them sooner. They are sturdy and very kid proof (at least for my kids). I love the push and lift design so little hands can’t just lift it open and they hold a lot yet blend in.

Handy boxes hides wire clutter.
Does what it is meant for. A bit hard to open once the top is fitted.
