Works as advertised.

Easy to install, instructions are fine. Initial operation and regular operation instructions could be a bit better, but study it, then it all makes sense.

Me hacen oferta y luego no me venden

Me hacen la oferta y cuando voy a pagar me dicen que no me envían a mi dirección, cambian el precio y luego si me lo envían, mal, si haces una oferta la cumples si no, lo que hacéis es engañar a la gente

Zatim neodzkouseno

Zatim neodzkouseno, ale vypadají dobře.

A very nice and well presented battery. Very happy!

Very nice product. Bluetooth connection is a nice idea. Also having the charge and discharge circuits controlable is also a good idea. A quick note onthe app used on thephone. it connects well and provides data on the current battery operation and conditions.
I would like to see some sdditional functions please;

Suggested features for app and battery software.

A. Data logging
Include logging of battery temerature, voltage, current and power. Logged data to be time stamped with charge, discharge events logged

B. Alarm and Warnings
Include function to log alarm and warning events. include battery conditions (voltage, current, temperature and operational mode).include time of the event occuring
I am very very happy with my batteries. They work very well. Thank you

I would be happy to discuss the above feature additions with you.

Great product and good support, they live up to their word!

The 4) 12V 628AH batteries I purchased came in good time and the price was very fair! If I had one wish it would be for the distance of the Bluetooth connectivity to be longer. Had one with a little dent and they made it right and updated their packaging to make sure it doesn't happen to others. So far I've gotten better support from Wat Cycle than any other vendor, they actually answer questions and work with you on issues!

All charged up

I purchased the 14.6V 20A Aluminum Shell LiFePO4 Battery Charger when I purchased two 100AH Mini batteries. I chose the aluminum shell for better heat dissipation since I live in the Southwest. Upon receiving the batteries and charger I put the charger to work fully charging the new batteries. The charger worked flawlessly and quickly charged the batteries. This is my second WattCycle battery charger, I also have a 60 amp charger that I use for my 300AH batteries. That are both very well built efficient chargers.

Absolutely the BEST Batteries!

I purchased two of these batteries for our travel trailer earlier this year along with an upgraded converter to match the LiFePO4 charging profile. They replaced two aging Group 24 lead acid deep cycle batteries. They ran perfectly the entire season between solar and generator charging. The weight savings itself is incredible. BT is such an awesome feature to be able to check individual cell voltage and balancing. With the new parallel function on the app, both discharge at the same rate. I can't say enough good things about these batteries.

Works like my other new WattCycle batteries!

I ordered a 12v 100Ah Bluetooth Mini like the other two that I have. It charged up just great and ran a water pump for a while yesterday. So far so good. The only issue I have is that the firmware on this battery will not allow me to use GoKWh or BMS Meta like the other two will. Until the WattCycle app shows total cycles, there is no way to check this value other than the two alternative apps.

Great Batteries But.........

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!

The 12 V 628 AMP hour battery is performing well.

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!

Great battery

Using the 100 ah battery on a 36 lb thrust trolling motor on a kayak. Ran all day fishing + still came back with 80%. Great to know I can always make it back home.

Seems to be a good

Seems to be a good option

Excellent!

I replaced the two AGM batteries in my RV with two of the 12V 100ah WattCycle batteries and there was an immediate and obvious improvement in power delivery. Couldn't be happier!

works as advertised

works great and stays cool with the cooling fan

So far so good

So far so good. Meets all my needs.

Good cells, construction, buggy BMS and balancing

Reviewing this battery for recommendation. Well constructed, small, screws to open are appreciated. great price. Unfortunately the 'smart' BMS suffers from current sharing issues when batteries in parallel and also from a balancer that barely functions.
It should be possible to fix this with some setting changes internal to the BMS, but I am not holding my breath.

Seams like a great deal.

Great price, great shipping. Charged at 70% when received. I charged to 100%, discharged to 50% and stored in basement for winter. Will use for trolling next spring. So far, so good.

Installed one 12v 314 Ah mini Bluetooth in our boat with Victrons Cerbo S GX

Installed one 12v 314 Ah mini Bluetooth in our boat with Victrons Cerbo S GX, Multiplus, Orion tr smart, smart shunt = Great 👍

So far it charged appropriately and holds the charge well. Capacity is spot on.

Aluminum shell battery charger 👍

I have both the aluminum shell charger and the plastic charger. They both work the same from what I can tell. The aluminum shell is heavier and feels like it should last longer but that is just my opinion based on limited experience.

Can't really give an honest review

Can't really give an honest review, as I have not received them yet. More of an issue with the Shipper than Wattcycle, as it did seem like it was shipped out promptly.

Batterie reçue sans problème

Batterie reçue sans problème, elle remplace 2 batterie AGM de 104 ah en ne prenant la place que d’une seule, je dispose maintenant de 314 ah avec plus de sécurité.Coupure de charge évitant la surcharge et la surchauffe, coupure de charge et de décharge en cas de froid selon la température, connexion Bluetooth permettant un contrôle du niveau de charge , de la charge, de la décharge et de la température.
