  1. Daly 200A48V Common Port BMS (https://www.aliexpress.com/item/32888385718.html?spm=a2g0s.9042311.0.0.212c4c4ds4sskw) R1900 Originally installed in March 2020, removed in Jan 2021. I pinched one of the balance leads at some point, but it only broke a few strands and not all the way through. Added a blob of solder to rejoin all the strands and ensure balance leads remained same length. Otherwise in perfect condition. Available for collection in Weltevreden Park, otherwise shipping can be arranged at buyer's cost (Postnet preferred).
  2. I assume it's this one: https://www.aliexpress.com/item/32997552090.html?spm=a2g0o.productlist.0.0.98612689xH5UV9&algo_pvid=9c57c7d2-d767-49c6-88f7-452a1dc47064&algo_expid=9c57c7d2-d767-49c6-88f7-452a1dc47064-5&btsid=0ab6f83115944754191536779e56d5&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_ I looked at that and then went and got the Daly instead... oh well, hindsight and all that. I actually had the batteries resting for a month on the Daly BMS, but I guess since they do voltage balancing and my cells all like to rest around 3.3v the balancing function w
  3. Thanks for this. Are you sure that the dynamic cutoff is only used in when grid connected, the ESS docs seem to imply otherwise (https://www.victronenergy.com/live/ess:design-installation-manual#dynamic_cut-off) The Dynamic cut-off mechanism effective both when mains is available and during a mains-failure (system is in Inverter mode). The primary scenario I'm trying to avoid is having the battery sitting at 40%. Then turning on a microwave for 2 minutes resulting in a cut-off due to a voltage droop. If this happens during no grid supply, I assume I'll unnecessarily
  4. Thanks, yea; I went through a similar trial phase that resulted in me buying a bench PSU so I could top balancing all my cells. The cells were all resting at the same voltage, but most definitely did not have the same SoC, so I had some cells spiking to 3.7v while the rest were at 3.3v during charge. I settled on 54.5v bulk/absorb and 53.7v float after that, so almost the same as your numbers, and have been running without issue like this. Also yes, using a Daly BMS, which I'm really not happy with... :(. It's a really expensive black box that has given me quite a lot of grief figuring ou
  5. So I've finally finished installing my backup system (just in time for load shedding it seems), and I've configured the ESS assistant. My question is this, are the voltages Victron have for the dynamic voltage cut-off extremely conservative? I've left them at defaults, but I feel like I should be lowering them quite a bit: 0.005C = 52V, 0.25C = 50V, 0.7C = 49.2V, 2C = 48V. With the standard 1.2V delta, and 50V sustain. My setup is a 48v system with the following components: Victron MP2 3000, 16x 120ah LifePo4 (https://lithiumbatteriessa.co.za/collections/cells/products/3-2v-120ah-lif
