    Mix matched batch

    Posted by Phil on Mar 23, 2024

    I received 5 cells that were manufactured together all one number off from one another but then the 6th cell was from a couple hundred batches prior and it came wayyyyy under voltage at 1.2 volts. After balancing and charging as of now its seeming to hold but time will tell. Other than that they work great!

    I first started with one bank 40ah then two banks and now I got 3 banks but waiting on the buss bars but the 80ah held up awesome with a mechman 370 it dropped to the high 10s so I think with this one more bank it won’t drop as much and I’m planning on getting up to 9 banks that’s 360ah lol
