    I have harvested a bunch of 18650s but I want to charge them and test them to weed out the bad ones, I think I need a PCB but I only seem to find LIFEPO4 ones, but I have Lithium Ion cells. I am looking for a 4S PCB.

  2. Avataaar/Circle Created with python_avatars Joey Garcia says:

    When you say "one C", what does that mean?

  3. Avataaar/Circle Created with python_avatars Paul S says:

    but it seems fiddly having to reconnect over n over thru the charging cycle

  4. Avataaar/Circle Created with python_avatars Ensei Mada says:

    How about putting an active balancer?

  5. Avataaar/Circle Created with python_avatars edwin kania says:

    Jehu,
    I see you have batteries in your house, are you afraid of any fire issue?

  6. Avataaar/Circle Created with python_avatars TheRustDigger says:

    Get yourself an arduino and make a 10x better BMS using those dumb BMSs..

  7. Avataaar/Circle Created with python_avatars Steven sousa says:

    How much for your 3s p7 Board kit with a BMS and how can I order them

  8. Avataaar/Circle Created with python_avatars Paul O'Connell says:

    Perhaps a tripod would help prevent audience from getting "sea sick."

  9. Avataaar/Circle Created with python_avatars smaco spasovski says:

    What about double sided pcb to put 14 cells so the pcb to be cheaper.

    jehugarcia,I have 16 gbs 300amp cells setup 16 divided by 4 ,making 1200 amp 12volt system . I use for my class A rv for chissis and coach the bms i need would be for coach side only the engine side would have no disconnect because of alternator .I have orion jr bms ,which has always had problems ,what would recommend for bms with reset able monitor system .thanks steve

  11. Avataaar/Circle Created with python_avatars Da ve says:

    Lol it probably the reason cell fail πŸ˜‚πŸ˜‰ I bet they leak energy if left for days and them FETs a bit close together all them would melt the solder πŸ˜‚πŸ˜‚πŸ˜‚πŸ˜‚ test with multimeter on cells connections to the monitor don't trust that 1 bit
    I've learnt balance leads am shit and adds resistance
