How did you roll back to a previous version? From Google Play Store?

Both solution number 1 and 2 would work just fine. I would go with number 2 and mount the leads diagonally out of each 195AH paralleled cells

At some point in time I considered Basen Tech to be a reliable supplier - but maybe not these days! With supplier would be a better one?

I have a facebook group in Danish where we build LFP batteries for our boats and since I opened the group I have recommended Basen Tech as being a reliabel supplier of GRADE A cells... Now my frinds have bought 16 x 304AH CATL and they do not seem to be GRADE A. QR code seems to be scratched...

Hi all! Need som advise regarding buying a 12V 600AH or 900AH battery bank for a 50 foot sailboat for a friend. (8 or 12 cells) A year ago I ordered 280AH EVE cells from basen and two other friends did the same as well. All went fine and we received 3 packages with undamaged cells and a 200A...

Wow this is very concerning! It seems you have received 3 different brands!!! Lishen, CATL and EVE

I went for Lishen because of the higher discharge rate than EVE just to be sure for my high amp bow thruster. EVE: 2C 30 secs Lishen: 2C 60 secs

I have similar experience as the thread starter.... I ordered 4 x Lishen 272Ah cells plus 6 bus bars and 200A DALY SmartBMS from Basen Tech. It took me so much time to decide which type of cell to order for my application. I wanted the cells that could take the highest discharge current for my...

Hi, How does the DALY 200A SmartBMS determine the State of Charge? We have seen the meter be at 100% just after top balanced 4 x EVE 280AH cells were connected Now when we topped the battery up at 14.3V the SOC said 93% How is this determined? Is the BMS integrating the Amps or is it just...

I am actually getting more and more confident that my setup for the bow thruster is going to work. I will connect the batteries without BMS but be using an active balancer circuit that I just ordered: https://www.ebay.com/itm/312774496524 BTW I just learnt that LiFePO4 cells are quite...

You can still discharge LFPs below 0 degrees C. But charging requires heating them up before you start charging. No big problem just turn on the diesel heater for a while :)

I am done with batteries with Lead in them :D I currently have a 50Kg 230AH Exide that is going to be replaced by a LFP solution.

Exactly! I know what you all are saying, I will continue connecting the thruster directly though. And then the two winches connected through BMS and charging / balancing through BMS. As said before - the thruster is only used in very short bursts when I arrive at a harbour single handed.

Well my Max Power retractable 12V is rated at 446A 4.8KW and 2C of the 272AH Lish is 540Amps. The datasheet of these cells says 2C for 60 sec. I guess I use the thruster in bursts of maybe 5-10secs and for the thruster I will go without BMS. I WILL connect a BMS though for an electric winch and...

Sounds good - you will get around 90% og the capacity using these parameters which is fine indeed. In my setup I will very seldom go below 3V also - I will probably turn on my diesel engine and charge if there is no sun for the solarpanels The only thing I am trying to say is that people seems...

The BMS will cut off when the first cell reaches 2.5V and the same goes for charging - the BMS will cut off when the first cell goes above 3.65V. I have been using my 300AH bank (3 x 100AH in parallel) like this for years - so within specs. And never had BMS cutoffs... Probably never...

In parallel they share the same voltage! So no problem in using the full specified range of the cells 3.65V to 2.5V

I will try a Victron Orion Tr-smart 12/12 30Amps for optimizing charging from the generator / start battery

Well I have decided to go for the Lischen 272AH from Basen Tech They are rated 2C for 60 sec and this should allow the thruster to work fine. The future will tell I will top balance them to 3.65V and run the thruster directly. The other loads will run through a 200A BMS from DALY

Thanks for your suggestions - so maybe I should look elsewhere than Basen Technology that seems to only have 1C discharge cells I need about 200AH because the same battery will handle the thruster + electric winch + anchor winch. The highest current load being the thruster but that one is only...

There is no problem in paralleling 2 LFPs with different capacity (or more). This is done all the time with capacitors of different sizes in electronics! If you take for instance a 100AH + 200AH LFPs in parallel and start discharging with a 300A load you will see that the 200AH is supplying...

Hi, Has anybody any experience with high current cells that can supply enough current to drive a bowthruster?? I have a Maxpower retractable that id 4500W about 450 amps and I want to build a lithium battery for that. The best I can find is CATL cells from Basen Technologi. These cells seems...
