Thanks for the info, my Victron MPPT can also reach the appropriate charge level, so I am looking for a way to get my alternator to produce it now. Thanks again

Is it possible to use my Victron 12/24 Buck Boost Converter with 3x Victron Orion DC/DC 24/48 Converters into a Victron 100/50 MPPT to achieve around 50 amps at 33v for my custom Nissan Leaf battery system? Or if anyone has any other ideas that I could use with the Victron buck boost (which I...

I am using and recommend the REC BMS, either the REC Q BMS or Active REC BMS. I also recommend buying the precharge unit, dc contactor switch, and bluetooth or wifi module (im changing to the wifi module) I am using the REC Q BMS and have it connected and communication with the Victron Cerbo...

I’ve currently got a perfectly operational system using the REC Q BMS and an 8S4P configuration. --- right now connector pin 1 is at the main negative terminal of the original battery configuration, and bms connector pins 2 thru 9 are attached to the 8 different cell positive terminals, lastly...

Ok great, thanks for the input, it is much appreciated. I am indeed aware of making sure to completely wire then plug in the wiring harness from the first install. Thanks for the tip on reducing the fireworks with the larger battery cables!

I've got more planning to do on the best way to tie in the new battery set but I was thinking I could build an identical second battery and then also wire it to the positive fuse (pre contactor) and the shunt. I've got to see how REC Q BMS needs it's cell wiring harness configured though. I've...

I am about to add a second 8S4P Nissan Leaf battery to my system and will need to turn everything off and go through some amount of disconnecting and reconnecting cables. I'd like to know what the safest methods and best practices in general are for disassembling a system so that I can rewire...

Thanks, having a look now at Meanwell

Thanks Picasso, I'll have a look at this unit

I've been enjoying my 8S Nissan Leaf battery bank and the mini split air con that it powers but would like to increase my charging capabilities. Currently I am using 900W of solar through a Victron MPPT to charge them to 32.88V. I also have a Victron Buck Boost Converter 100/50amp 12/24v...

I use an 8S 24v configuration because the 3S will leave you on the very low end of 24v operational voltage range and will be a problem with most inverters and other components. The bms I am using is the REC Q BMS and it is working exceptionally well. They offer bluetooth, wifi software, pc...

Im using an 8S Nissan Leaf configuration as well and use the REC Q BMS and can say that it works perfectly. It's not the cheapest but just wanted to mention that it does in fact work well with the stated configuration. Enjoy your adventure.

I'd love to know if there is a way to reset the contactor after the REC bms has disconnected due to low voltage that doesn't include using the REC BMS PC software. I couldn't get my systems back online after a LVD until I set a new low voltage parameter. The BMS had opened (broken the circuit)...

Ah yes of course, my initial excitement of the possibility clouded what I know to be true

An awesome idea to use the converter to feed an mppt which can then bring the voltage to 33v! I’m using a 12/24v 100/50A victron buck boost converter and plan to continue using a 24v nominal system. If my converter outputs 50a at 24v Im assuming the 100/50 will do the trick but maybe give a...

I am using an 8S4P Nissan Leaf Battery configuration with 16 modules and so my operational voltage is around 28-33v. I use a Victron MPPT and Buck Boost converter to charge the system but the Buck Boost can only be programmed to charge up to 30v normally. I'm curious if it's possible to increase...

Also, does anyone know what the "Send data to VE.Can" is for in the second picture under CAN-bus(1) profile settings?

As stated in the title, when I change my battery capacity in the REC BMS software it does not update to the new capacity in the app on my phone. I've tried disconnecting device, forgetting device, reseting settings in software and so on. Has anyone else experience this issue, or have any...
