Deal Details
Just saw Will Prowse's review on the version 2 of WattCycle's 314Ah (non BT) battery where he praises the internals of this battery saying "it is on a whole different level" and "it is over built" and overall "this might be my favorite battery from them".

He also did a capacity test at .2C or 62.8A and got 329.6Ah, and another at .63C or 200A = 316.2Ah. There are many other videos as well where all capacity tests performed was over the stated 314Ah.

Check out Will's review here: https://youtu.be/RBVlEk5_hpE?si=rj0D4svWaML5Fd_K

Then I emailed their CS team stating I saw Will's review and was wondering if I could get some more discount. They gave me a code and so I am sharing it here (it seems like if you just ask them if they can give more discount, they would).

Honestly it is just a matter of preference. Will stated he hates smart batteries (non BT). But if you are the type that wants to know every detail of the battery then BT is the way to go....of course it is a little more expensive.

I still can't get over the size of those busbars how nice the internals look.

Just curious, you put 4 of these together in series and it would be 48v but still only 314wh? Am I getting that right?

I had bought the D40 charger accessory for my AC200L , and it was just sitting in the box collecting dust...no 12v batteries ...so I bought 2 of these. The D40 charging them at 20 amps, should be done by midnight 😂

Sorry to hear that. When did you email them? I know they monitor emails on Saturday over there (Friday in the U.S.) but they don't work Sundays.

Let us know what their response was. Yes this will be a test of their CS dept.

Box was fine, not a scratch on the battery...I think the weight of the cell assy and cage around it...with extra weight of the bus bars...was dropped square in shipping...so the case stopped...but the cell assy inside kept moving...impacted the top...and broke the locking tabs ( Strange, no glue noted sealing the top...maybe they forgot the glue on this one during assy ( Or if high frequency welded plastic, missed that step ? )
