Hi everyone I would like to have any feedback about usage of sunwoda batteries with Victron multiplus 2 48/5000/70. Are these batteries better than pylontec and are the sunwoda atrix 5k a good choice to combine with this multiplus. Thanks in advance for your feedback. They mention that it can be discharged for 100% while pylontec they advise 90%
for communication I would try the Victron CAN cable type A, or if not type B, the battery may well get recognised once the CAN data is correctly connected. The supplied interface cable carries both CAN and RS485 data, so should not be used directly. I don’t think these are on the Victron approved list of batteries, where performance has been tested.
Also: Any liFePO4 battery can be discharged to 100% (typ 2.5V per cell) except that if you do this, instead of discharging to 10 or 20%, you impair the life of the battery say 2000 cycles instead of 4000 cycles.
From what I saw it was recently included in the list of Victron compatible batteries.
Regarding fully discharged indeed all of them are able to be discharged compleatly sacrificing the number of cycles or battery health. But according to the specification this one is not compromised by that and specifications say 6000 cycles as reference…
that’s why I was trying to find someone with practical experience because it’s always a little bit diferent from specifications and the way you use it can influence a lot
I’d take that with a large pinch of salt. Most batteries have an expected lifetime if left on float charge @100% Soc, and a finite energy throughput ( total kWh cycled in and out). Hence DOD will always affect lifetime. if ‘cycles’ are calculated as the equivalent energy of a 100% discharge of nominal capacity (i.e. 2x trip 40% to 90% and back again) then discharging to different depths gets a bit more normalised. However if one routinely discharges all the way to 0%, then this will result in a shorter lifetime compared with terminating the discharge at 10% SOC. some chemistries are more susceptible to this than others.
