Well my 100Ah Wattcycle battery took a week to arrive. The case is just the normal type case as you see on many of the cheaper batteries with a webbing strap. It is just slightly shorter than the VoltX case and about 10mm higher so always check the dimensions of any battery you buy. The VoltX case s a somewhat nicer case but in reality the case means nothing as there are four prismatic cells in both batteries which will be very similar.
Numerous tests and tear downs have been undertaken on the Wattcycle so all Im interested in at the moment is the capacity. If something went wrong with it then I would send it back under warranty but if no success then I would tear it apart and put anew BMS in if needed.
The battery arrived at 13.2V, was charged to 14.6V and then settled at 13.88V the following day.
I undertook two discharge and recharge tests and they all came in at around 102.5Ah. For the price of $275.99 it would probably suit many who are looking for an inexpensive LiFePO4. I had no problem charging to to 14.6V for a full charge and discharged it down to 10.5. 10.00V is considered fully discharged and I could have discharged it down to that voltage but it would have produced only a very small additional power.
If you think spending more money will get you a far better battery then take a look at the tests undertaken on the Deep Cycle Systems batteries and the lawsuit against a reviewers YouTube review.

The other consideration, Tim, for these batteries is the number that can be connected in parallel and in series.
Yes Dick0, Max. 4S4P, and they come in 100Ah, 200, 280 and 314. Can build a very nice power bank if needed.
