      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.

      Damaged on delivery

      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.

      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.
      Garantie de 7 ans après enregistrement sur le site.
      Installation très facile

      Works perfectly!

      After reading and watching many reviews about all the popular brands, I selected the Wattcycle 100ah battery. I run a drywasher and highbanker sluice (gold prospecting equipment) off of the battery and have found that the power output is consistent and plentiful! Even after running the better part of a day, there is still enough energy available to run the next day. Charging is fast too. Thank you Watt Cycle!

      3 Pack charging and discharging together

      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.

      Great so far

      Great so far. Good price! 103 ahr capacity on first test.

      Excellent Battery

      I bought this battery for my 2024 Coleman Lantern 17R camper, and it worked extremely well. The price is the best you can find while still getting a high quality and reliable battery. Highly recommend.

      Batteries installed since almost 2 weeks in my travel trailer

      Batteries installed since almost 2 weeks in my travel trailer. They are doing their job. BMS are reacting ok at 14.6 volts. Even with all the BMS protection settings, People on the forum encourage strongly to fuse those batteries in case of a BMS failure. So, MRBF fuses seems to be the best choice for that.

      A definitly good value for an excellent battery

      In the past i have always used Renogy but decided to try wattcycle. I have not been disappointed. Delivery of 3 business days was much faster than Renogy 4 months. The Bluetooth app works great, the batteries perform as good as Renogy and cost much less. Definitely going to use wattcycle going forward.

      Simple. Easy. Works

      Easy to install. Good instructions. Accurate.

      I’m enjoying the extended life of these cells mind you I had to modify the wiring to accommodate reversed poles of the units. No worries not a problem that I couldn’t solve. Thank you very good so far no problems getting them to fit in the enclosure.

      Excelent

      Excelent

      So far great trolling motor battery.
      Only used two times, so time will tell!

      Good battery’s

      Got them in a timely manner. Been out 3 different days fished daylight tell 4pm still had 89%

      Lots of capacity in a small box

      Several good reviews on youtube for this battery. I have not tested the battery to it's limits, but it does what i need it to do.
      I created a diy "solar generator" for my balcony solar system to help with offsetting my grid consumption, and the 3kwh capacity of this battery will go a long way.

      I did not have to use it so I cant say well it worked

      I did not have to use it so I cant say how well it worked. good piece of mind though
