Snelle service goed verpakt
App werkt prima ben hem nu aan het testen
Alles werkt goed tot nu toe

Everything is working perfectly under high load and the tested capasity was as promised.

It arrived quickly, although I haven't used it yet, the voltage is fine, I was able to charge it. I don't know exactly what secondhand means, but it looks new from the outside. I have previously bought 2pcs 24v/100Ah batteries from them and have been using them with satisfaction for my solar system for about a year. That's why I dared to buy a battery for my small boat here.

I am satisfied with this battery and I was surprised that by discharging and charging it I obtained a capacity greater than that indicated on the label, 266 w/h. I do not recommend discharging it below 11.5 V, this is so that you can have it for a long time and it will function within normal parameters. I recommend this type of battery with confidence. And the order came quite quickly and I recommend the seller.

De perfecte boot accu voor schip van 10 meter.
Ook in de winter als de zonnecollectoren weinig leveren en koud weer is. Is de verwarming in de accu perfecte keuze. De 12V hetelucht verwarming doet het perfect op de accu.
Wat een uitvinding, super Watt cyclus.

Per ora do 4 stelle perché non l'ho ancora installata ne provata, ho solo collegata con Bluetooth e il tutto sembra funzionare benissimo ed è carica al 66%. penso comunque che sarà un buon prodotto.
Dalle recensioni che ho letto è visto, penso che sia uno dei migliori prodotti come qualità prezzo.
Posso solo dire per adesso che sia l'ordine che il trasporto (consegna veloce e perfetta come da foto) tutto ok 5 stelle.
una sola cosa ho visto che non ha, "il bilanciamento delle celle attivo ma passivo. Questa è una pecca, spero che le prossime avranno il bilanciamento attivo delle celle. Per adesso grazie.

Great value for a 12 V 314 Ahr battery complete with Bluetooth connect

De batterij is super klein wat echt top is voor mijn setup. Ik ben WattCycle tegengekomen op een YouTube video van Will Prowse en het bleek dat WattCycle goede kwaliteit leverde dus ik ben blij met de batterij. En gebruik de app meerdere keren per dag om alleen maar even te kijken hoe vol die is. De app is prima. Het zou wel fijn zijn om de cycles van de batterij en een charge en discharge geschiedenis te zien in de app!

The amount of power in these things for their cost and size is amazing! The build quality seen in many videos around the internet appears to be top notch. These are half the weight and 2/3’s the size of the current house battery bank in my boat with nearly 3 times the usable power. Shipping only took 2 days and arrived without issue. Product registration was simple and the app connected to the BMS’s with ease. Very impressed!
Thanks WattCycle team!

Paired with a 3000W inverter in my Class A Motorhome the 300amp BMS exceeded expectations. The Bluetooth app works great as well.

If you’re thinking about which battery to pull the trigger on, go with this battery, you won’t be disappointed.

Works wonderfully with the Ecoflow 800 watt alternator charger plugged into a Delta Pro 3.

I like using second-hand products, it's part of my "waste-not" way of life. That's why I decided to try out WattCycle's second-hand batteries as an addition to my home's energy storage.

Got a second-hand 24V 100Ah a week ago and just had the opportunity to test it, using a Victron SmartShunt. The battery charged to 28.4V (which means that it's not 100% balanced) and gave out 100.6Ah of energy, down to 20.0V. Impressive. I will be testing the battery again, after balancing. I would expect it to go over 102Ah.

I use 2 of the 280ah batteries and have been extremely happy with them over the last 1.5 years. I also choose to install the 314ah minis in most of my customers RVs as I own an RV solar installation company. Happy customers!

Getting ready for the life in the wild. Everything working and looks great for now! App shows the state of the batteries and voltage for each battery cell.

I love these batteries. I replaced 10 100Ah 12V batteries in series/parallel. If you have a 24V system, I highly recommend that you go with a native 24V battery.

The only hiccup at this point is that there is no way to parallel these batteries (software), so sometimes the batteries will discharge at a slightly different rate. Tech support is working on this, and a software/firmware fix is promised soon.

I do professional Battery/solar system installations in RVs and have seen quite a few batteries through the years, and the build quality of these batteries is definitely top-notch!

It has been in operation now for 6 days.
We are happy with this product.
We are suppliers and installers of off-grid solar systems and Wattcycle is now on our supplier list.
We just bought a second battery!

I started with 3x LiTime 100Ahr Smart Mini for a power system in my Jeep. Had issues charging and discharging as a unit. I also had issues with cell balancing. Replaced them and the problem remained so I returned them.
When Wattcycle came out with their parallel mode, I bought a 3 pack. It works great. I have not enabled parallel mode as the all three share the load well. Charging and discharging together. Also, all three batteries are behaving well with regards to cell balancing. I have been very pleased.

The only down side was the nice battery mounts from American Adventure Labs were built for the Litime battery, so I used straps for the Wattcycle.

Bin sehr zufrieden mit dem Produkt hält was es verspricht
Gerne wieder.

Charger box and charger damaged from shipping. Yes probably cosmetic but still, I didn't pay for damaged products.
The charger box was wrapped in black plastic then taped on the battery I purchased without foam or any protection.

Light and powerful battery to caravan. Just what I need.

Great value for money. The size is perfect under the sofa in the van.

i’ve taken it out on three fishing weekends and this battery is working excellently as a trolling motor battery. I’m running a 12 V 55 pound thrustMinnKota and there has been no issue with power delivery. Charging has been predictable. It’s great having such a lightweight battery to replace the red acid beast. Did about six hours trolling this last weekend and probably about 30% off the battery used.. very impressive! Hopefully it lasts as long as advertised :-). My only minor concern would be the strength of the plastic enclosure on the battery… It doesn’t seem quite as hefty as the lead acid types
- so I’m being careful not to put it down on sharp gravel and such. This might be unwarranted… As it might be perfectly sturdy.
