Hello all,
I have decided to upgrade my battery bank and need a little help from the smart people on this forum. I previously built 4s2p 272ah Lishen cells (544ah) managed with JDB's bms.. The system is charged with an Orion 30amp dc to dc charger and 400watts of solar.... and when I want to run my generator, I can plug the victron inverter in and really get the AH in... My biggest issue is getting/keeping the cells charged up...
My electrical load includes a 4 camera security system/dvr, isotherm, S3, fans, induction cooktop, microwave, 24inch tv, ps5, pumps for engine heat/floor heat/shower and charging phones/laptops/gadgets... and well... if I could charge better I think it would work out okay..
When I am connected to my generator, I can charge at 50amp per pack, and it takes about 2 hours to load the cells up.... and that got me thinking and ultimately pulling the trigger on the nations 280amp dual alternator for my van… In that conversation I decided to upgrade my bms to a REC Active BMS system… They look legitimate; the hardware form factor reminds me of a cradle-point or pepwave router and looks pretty robust…
In the same effort to stop messing with my power during ski trips or when shaded by trees, cloudy days etc I also order 16 304 eve cells….. I hope 1200 AH of lifepo4 will stop any power insecurities I currently have as a full-time van dweller that works remotely.
I’m back at the start and need help with the form the REC people sent me, since the vernacular doesn’t match the xiaoxiang parameters, I’m stuck and hoped the nice people of the forum could help me.
This is what they sent me
