]I removed the pairs of modules from the water cooling system. I then rebuilt the pairs. I used a piece of 3mm steel plate, placed between each pair of modules then used the plastic material supplied on each side of the plate. then I bolted the pairs of modules back together using 6mm stainless ...

So I thought an update on this project may be called for.

I'm pleased to report that I have commissioned my new off grid power system reusing the battery from a 2022 build Peugot 208e. The battery breaks down to 18 modules, each consisting of 12 NCM cells 2p6s. Nominal voltage is 22V and capacity ...

Thanks for your input Yasko. I was of the opinion that the water cooling would not be required with my relativley low level charge/discharge, nice to have a second opinion.

I plan to be in touch with http://www.wdrautomatisering.nl/ as suggested by "EV Builder" for the BMS controller. My son is a ...

I wondered if any one who is reuseing these modules has a view on the integral cooling system and whether in a static off grid set up the active cooling is needed. I would not expect to be charging or discharging at a greater rate than 7Kwh .

It would be fairly simple to plumb the modules and ...

Sorry missed your link at first glance. Found it now; that looks really useful, great.

I plan to put them in 2s8P to give 44v and use an Outback inverter charger. The Outbacks nominal 48V settings have a wide enough range to accommodate the lower nominal battery voltage. I will have 2 inverters in parallel to give larger supply and charging capacity.

Sorry, which BMS system was that.

I realise that "looking the same" is not very scientific, but the thread here appears to be covering the same battery modules set up. https://openinverter.org/forum/viewtopic.php?p=35581#p35581

For the sake of discussion. IF the modules I have are "the same" what will be my 1st step to repurpose ...

I'll try again but by eye, these 3 items appear to have no markings visible. They are coated with a varnish like treatment which renders them opaque. I will try to find some magnification device and come back with any info obtained. Thank you for your interest. Andy

Hi Yasko, hi Tom. Thank you for your replies. Yes the board over the cells appears to be same/similar to the illistration you provide. See mine below. I have the complete battery pack with all modules and the wiring loom. The daisy chain terminates at what I assume to be the main battery control ...

So I notice that the 9 modules are all connected daisy chain in series all the way back to the main control module. The daisy chain loom consists of only 4 wires . From this I deduce that the individual modules board must be doing the actual "work" ie balancing cells, etc and the 4 wires are ...

Hello Jacob. Thanks for pointing out my error, caught by terminology. And thanks, I've found the upload as well. Each module is 6s2p 22V nominal. Each module is built paired up in its water cooling pack, so 44VDC, so 9 x pairs of modules is 400V as built.

So what I'm looking for is the simplest way ...

Hi, just joined you all. I live off grid in the UK (25 yrs with a 24KWh FLA set up using Outback inverter charger. 6.5Kw of PV and 3 Kw wind turbine. 24V battery) Also 10KVA gen set on Auto start.

I wish to double my battery capacity and upgrade to a 48 V system.

I have just purchased the ...
