When paralleling 2 12v batteries, it is best to take all loads from, and place charging sources on, the - of one battery and the + of the other.
When putting 6v batteries in series, to form a 12v battery, one HAS no other option to put one - cable on one battery1 and the + on the battery2, as if one put both clamps on the same 6v battery, they are hooking a 12v charger to a 6 v battery.
Automatic EQualization charges are not something I would want an automatic charger to decide to initiate on its own. 15.8v, is too high for some electronics which might still be hooked to the battery. these EQ voltaegs can indeed remove some sulfation, and in fact are more effective than the 'pulse desulfation' chargers which people seem to believe are magical battery restorers.
Pulse desulfation is a marketing buzzword. Its been proven to have o more benefit on sulfated batteries than a chrging source holding them at equal voltage for the same duration. the US navy tried this way back when on diesel electric submarines and found the pulses damaged the plates faster. YOu will not find a lack of glowing testimonials though on Amazon or on forums.
Trojan and Rolls Surrette spec 16.2v for EQ charges but Trojan a few years ago spec'd 15.5v.
A few years back people were wanting the harbor fright manual charger as nothing else was easily obtainable that could push a single 12v battery to 16v if left on long enough.

The link above will be able to take much better care of a pair of gc-2s so much better than any garage style charger. It is worth the price. Dont let the lack of DC cables put you off, Cut an older set of 6awg or thicker jumper cables in half and you will have an incredibly powerful an capable portable charger that will smoke anything deisgned for the garage and the occasional flat
starting battery on a neglected vehicle which sat too long or had its dome lights left on overnight.
Remember the charger you are getting is not going to be on a small capacity starting battery, it is going on a pair of GC-2's with 3x or more capacity, and which if depleted enough can demand the charger to run flat out 3x longer, or more, which the designers never intended. Well they might have but the bean counters neutered them and cut fractions of pennies off of everywhere.
Yes any charging source can work, and can get batteries towards full, perhaps nearly full and rarely truly full, but a garage charger on a pair of GC-2's is like taking an Econobox with 14 inch rims and 4 inches of ground clearance offroading and wondering why you got stuck and broke something.. You seem to be trying to find the best econobox to take offroading, and unless somehere has tried to take that specific econobox offroading, they/we can only guess how well it will do and how far it can get.
Once stuck and miserable, one will wish they paid more and bought the 4x4 instead.
That said my Schumacher sc2500A, rated at 25 amps is providing 29.62 amps/394 watts as I type and only has the battery upto 13.6v so far. In another 60 minutes or so I have to be careful of voltage exceeding 14.8v. Even on the AGM setting. It can't be trusted. nor left alone. My Meanwell, can. it will never go above the voltage I have chosen. The PD can, it will never go above absorption voltage, either 14.4 or 14.8 depending on the version bought.
Any random garage charger with chingrish instructions, well you will have to tell us what it actually does, but seeing as how you have not bothered to check the max voltage or ampergae used to get there of the Cen Tech which you have, yet don't trustt.....well good luck on that offroad trail in a lowered prius with bald tires.
Seeking 'best cheapest' will be regretted, its just a matter of time and delusion for that duration.
