I think the first thing that comes to mind is: What on earth is the HA category? This is Pajda’s term 
(it took me exactly about three seconds to come up with it) for “High All-in-one” or simply “High All”, which obviously falls between HE and HP categories. Essentially, this should be the holy grail of battery technology that we aim to achieve.
Samsung was undoubtedly the first pioneer in 2021 with its INR21700-50S model. In addition to high energy density, 50S offered a continuous discharge rate of up to -4C and fast-charging rate of +1C, all at a reasonable price and, most importantly, with global availability. The only notable drawback of 50S was poor cycle life at high DoDs (you can view the 50S results for free on my Patreon channel). Today, the 50S has been completely surpassed by competitors such as the Lishen LR2170LE.
Some time has passed since then; although the energy density of the HE category has been increased to 5,800 mAh as the standard, essentially none of the models have been able to deliver what was expected of the HA category. I had high hopes for the Molicel M65A, which was announced at least a year ago, but unfortunately, it still hasn’t made it to market. The actual estimated availability date of M65A is July 2026. Other players in the market took advantage of Molicel’s delay and brought us models that are already commercially available, such as the Reliance RH60, BAK 65E, and the Linkdata 60P. So far, I've had the RH60 and 65E, in my hands and both definitely fall into the HA category. The Linkdata 60P even aims to the HP category. I have now ranked the Reliance RH60 at the top of this category precisely because it delivers consistent results across all parameters. In addition to performance metrics, the global availability is also very important factor, and the RH60 is already listed in the catalogs of both EU and US suppliers. Unfortunatelly I can't say the same about the BAK 65E as its weak point is its lower cycle life, especially when fast charging is required. (If you'd like to see the results of the BAK 65E, please visit my Patreon channel).
And now for the results:
