I have 4 of these running in series for the past 8 months on a 48v Victron Multiplus II with a Smartshunt for midpoint monitoring etc.
This has been my load shedding backup system. The most i have asked of them at any one time is 15A. Absorbed at 56v and floated at 54v, never been below 85% SOC. Overkill for occasional load shedding.
With load shedding seemingly getting worse, I've started to invest in a PV array to move away from Eskom. I'm wanting to increase my battery capacity as i am limited to 4 of these, as they cannot be paralleled. These are great for someone looking for a solution to get you through load shedding.
Durban based, more than happy to have you test them for peace of mind, or i can show you the VRM shunt logs since installation if you're a fan of numbers.
R4000 onco each.

Victron 500A Smartshunt, 6 months old, still under warrantee etc (only available once at least 2 above batteries sold) R1650 onco.
Take all the above as a bundle and get the shunt for free.
