I have a Daly 12v 250 amp Bluetooth bms connected to 560amp 4s2p battery. Has been operating perfectly last 4 or 5 months with 3000watt inverter. It’s installed in an RV and has travelled many miles of very corrugated roads. Inverter was recently switched on to boil a kettle and bms switched...

Looks similar to an Enerdrive product in Aus which is very popular here.

Mayhaps.... I've just ordered some Lishen 272ah for another 12v pack.. see how they fair.....

I've had similar and the cell is being replaced by Basen. (This is the second cell to be replaced out of 4 but no real problem with Basen replacing - just annoying) All top balanced fine. Used the battery for a few days recently camping running a 12v fridge, water pump and lighting...

120amp with bluetooth, 4s config as below.... i soldered in a two pin header for the switch port but perhaps this can be done by them prior to shipping.. I should have asked... https://www.aliexpress.com/item/4000776528805.html?spm=a2g0s.12269583.0.0.246052579u6paa I did not weigh the cells, I...

Will explains it here....

A low volt 1000w inverter alarm sounded when a 60amp load was applied to the 12v battery and then cut out. Cell volts indicated a low volt issue under load from cell two as below.... Disconnected cells, ensured cell two was charged and did a capacity test on this cell. Capacity of the cell...

Yes, couldn't believe it, just my luck I guess. Communication with Alex is great. I used a little loctite on the screws to help with issues of dissimilar metals down the track but suggest terminals are well cleaned once loctite is dry... ended up light sanding...

I've been dealing with Alex Chen and paid $431.00 door to door for x4 280ah eve cells. Purchased 6 July 20 and they arrived in Australia by sea door to door on 8 August 2020. I asked for 6 bus bars and screws so I could top balance and have since doubled them up for the 12v battery as they are...

Ok ta, won't stress over it other than puts me behind a month or so, it's being replaced with me paying the postage but I do wonder what the failure rate of these cells are or was it just one in a million and my bad luck?

Hi, I'm rather new to LiFePO4 and this forum has been fabulous in setting me up. I've recently received 4x 280ah eve cells that is assembled 4s. All arrived very well packaged and cells arrived at 3.34v or thereabouts and I top balanced - all looked new and unused.. very slightly 'bloated'...

The low cell at 2.76, once the load is off goes back up to near match the others. On charge it is always the first cell to reach highest charge, and when at around 3.5v the other 3 will be at 3.42 or thereabouts..

Similar to Red, put a 4s 280ah eve pack from Shenzhen Basen together last week. Top balanced all seemed good, at idle all cells 3.34v, With a 63amp load 3 cells are at 3.2v and one is 2.7v.... suspect a dud cell?
