Great charger for lifepo batteries

I wish they had a 80 amp charger for faster charging.

Very easy to use, very competitive price. Seems to charge very well!

Great no-frills charger

Gets the job done

suprisingly good

Overall this is a good quality charger that is cut and dry to use. If i could change 1 thing, i would install an on/off switch so im not having to unplug it as i hook it up to another battery.

Great charger for my 12 volt lithium batteries

I am amazed at how much more quickly this charges my Wattcycle 100 Ah batteries compared to my other Duracell and Noco Genius chargers. It works great to charge them individually as well as when I have 4 in parallel for my 2000 watt inverter. Even on the lithium settings with those other chargers, they never seemed to be able to get the battery fully charged before shutting down and acting like the charge was complete. Having the bluetooth variety of these Wattcycle batteries let me know that they weren't fully charged. Now I know the Wattcycle charger is working great to fully charge these batteries.

We’re so glad to hear that the WattCycle charger is performing so well with your 12V lithium batteries and providing the full charge you need. It’s great that the Bluetooth feature helps you track the charging status accurately. We appreciate you sharing your experience and highlighting how our charger compares to others.

Best Lithium Batteries on Markwy

Bought these to replace old lead batteries in golf cart my girls ride around the neighborhood.
These batteries hold charge for days and gave the golf cart considerably more power

Good stuff

I like the charger and it gets the TM batteries to max capacity pretty fast. There was a small sticker on the cables and it made the cords sticky before i removed it…not really an issue but I wasn’t thrilled at how much goo came off such a small sticker.

Great battery/ Great price

I haven't had the battery long enough to see battery full potential and charging times. Soon though.

Does not record or track low current discharging

After living with and testing the 315 Ah BT 12v battery I can confirm that when using it to power devices around 1.5 amps or less, the app shows the battery in STANDBY with no current being recorded. Even after 50 Ah or more has actually been used over a few days, the battery percentage states the same. This is not just a problem with the app not updating (which also occurs at times) but the shunt in the battery just does not seem to be able to detect low current levels. Sometimes discharging would show up with current draw down to around 0.8 amps. But at other times even 1.5 amps would not be shown. The cell voltages record fine meanwhile. Unfortunately, as I use this battery to power a radio that requires 0.5 amps in receive mode, I need to add a Renogy battery monitor (an added $100) to know the SOC of the battery. So, if you use this battery where discharging is always about 2 amps or more it will be OK, but be aware of this problem at low current levels.

Excellent value

Everything about this battery is working great. Only wish I had bought 3 more. Hope to see them back in stock soon

Charges fast…works as it should.

Excellent LiFePO4 Battery

Bought this second battery to use in series with the first battery to make 24V battery bank to run my EG4 direct solar 12,000 Btu 120V ac mini split overnight. I can air condition 600 square foot area with just 2-12.8V 280ah batteries in serious. Although we did another video where we ran this mini split overnight with just one WattCycle 12.8V battery and a 120V ac output inverter Keeps area 600 sq ft area 76-78 degrees overnight even with it being 116 degrees outside yesterday. Still have 40-50 percent state of charge left in batteries in the morning when the battery bank is charged up again. I will definitely buy more WattCycle batteries. Have been using for several months now, extremely reliable for me. Highly recommend the WattCycle batteries.

Nice battery but could be better

New to WattCycle, but I like the value and overall build quality of your batteries. However, the app leaves something to be desired. I like the BMS access via Bluetooth, but more details similar to what I get from my Victron smartshunt should be included. My advice is to redesign the app to provide more details and historical data. Id also like to see a physical button to manage a few things on the battery such as power -Greg

Seems good so far

Great battery and responsive customer service.

I am 100% satisfied with my battery. Also very pleased with customer service. Their price match guarantee is something they stand behind as promised.

12V 280Ah

I’m very pleased with my purchase of 4 of these and the customer service needed for one defective BMS.

No problems

Was shipped in a timely matter packaged well came to the door in good condition

They serve there purpose

Using mainly for trolling motor.

Outstanding Battery/Outstanding Value

This 12V Lithium battery mini, has a the capacity of 3, 100 ah lithium batteries at almost the size of 1. This battery fit perfectly in my RV slot that held two 100ah lithium batteries. The features on this battery, the high quality build, and the affordable price tag, make this battery a great value for a great battery. Highly recommend.

Good transition with Watt Cycle

Great battery product. A good transaction with them. The 314 ah 12v battery shipped from California and arrive about a week after ordering.

Battery arrived with low voltage would not take a charge -refund received

The battery arrived with 2.85 Volts and would not take a charge from any of my LifePO4 chargers - even the ones that said the could re-activate batteries that were shut down. I attempted all of the troubleshooting from Wattcycle tech support to no avail. I was promptly refunded.

Good amperage batteries for their size

Batteries arrived in good shape & well packed. Came with short & longer bolts which was helpful. I installed 4 of them in a boat as the primary house side. They replace 4 each 210 AHr AGM batteries that were half again bigger and twice as heavy (120 lbs each) as these ~60 lb 314 AHr LifePO4 batteries. This tripled my house capacity & removed 240 lbs of the weight. I added 250A MRBF Fuses to each +positive battery, as well as a 350A Class-T fuse on the overall DC+ side. Additionally, I added a Victron 500A Waterproof SmartShunt to monitor the charge/discharge levels. For charging, I added a Victron Orion XS 50A DC to DC charger for the alternator, and a 40A LifePO4 AC to DC Charger with a remotely activated plug. So far, the batteries seem to be working as advertised.

4 Batteries for Golf cart

I purchased 4 batteries and a charger for our golf cart, to surprise my husband. They arrived in a timely matter even with the tariffs going on. My husband was so very happy. Our golf cart is a creation that my husband created....it was 36v now it's 48v....I don't know it's a lot of stuff, but what I do know is we pulled a lot of batteries out of the cart (8 I think) some for the cart one for the radio, a lot, about 500lbs of batteries give or take and now we have just 4 LIGHT WEIGHT lithium batteries installed and that cart hauls a$$. I upped his life insurance and my medical.
I will definitely recommend this company. Both my daughters and their husbands have golf carts and they have already said when it's time, they are going this route.

12V 314AH LIFEPO MINI

Installed WattCycle’s 314AH in our camper with a new lithium charge inverter. Also installed a 2000 watt inverter and an auto transfer switch. I couldn’t be happier. The WattCycle 314AH performance is exceptional. I previously had two Trojan deep cell golf cart batteries which contributed a lot of weight. Though they were decent batteries they don’t compare to WattsCycle’s 314AH, in performance and weight savings.
At first I thought the battery I purchased had an issue. It was showing only 5.6V on the multimeter. Come to find out that WattCycle’s Bluetooth app. has two buttons to turn on and off charging and discharging. I had discharging turned off. When I hit the discharge button on the app. everything came to life.
What an awesome option.
Hoping to add another 314AH in the future.
Awesome battery and Company. They quickly responded to my emails. Great customer support.
Chris

Awesome produc,t excellent price, and super fast delivery A++. Upgraded to a 36v system from 24 in less space. Just know that you have to charge them overnight they don't ship lithium batteries at full charge

Right battery, wrong posts

I ordered a battery and the threaded posts were too large for the battery.

Works great

I got the charger with my 100ah mini and everything works as it should. I’ve used the battery 3 weekends running my trolling motor and fish finder and it still has 77 percent at this rate I’ll only have to charge it 4 or.5 times this Summer so if it lasts 5000 cycles it will last me 1000 years great buy

Good so far

Only have had it installed for about a month, the only thing so far that I would like to see changed is more mounting holes, that way you have more options in tight places like I had to mount it.

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.
