[QUOTE="Ucatchmydrift, post: 531398, member: 35106"] Thanks for the video, i shall watch that later.. Looks like somthing that i would really enjoy doing actually. Only problem that i can see is cost. For two 24v roamer batteries giving me 9.4kw useable it costs £3500 To diy the bank using the cells you posted above, including daly 200a bms with bluetooth, i would need 16 cells giving me 4 x 12v banks. Run in series and parallel to give me 24v. Im guessing here, but i take it each 12v bank would need its own bms, so i would need 4 of them at £140 each. Cost of 16 cells totals £2880. Total = £3440, thats without the cost of making the boxes to put them in. I would get a total of 11.5kw which is more than the 9.4kw, but including box parts, it woild probably total about £3700? Roughly. Unless i just want a project to do, im not sure its worth it, unless im getting my maths completely wrong, which is quite likely 🤔? [/QUOTE]
