Needing a 16S Smart BMS with Low/High volt signal for external solenoid...

[MCJEFE]

I would like to find a 16S Smart BMS that will control an external solenoid or contactor to isolate the pack, rather than a circuit board mounted FET or contactor.

I was running a Zeva BMS in my cart which is using an Gigavac contactor to isolate the pack. I would like to continue to use this type of a setup rather than the typical BMS FET control.

Any help would be appreciated.

The latter two JK models are relay type. I do believe that the cell count can be less than 24 but confirm this. They have excellent 2 or 5 amp built in smart balancers too. Eel battery may be able to obtain this for you. Contact Howard though the site he’s really good at getting back to you.

I've seen those and may end up with one, but I'd really prefer to use an external contactor controlled by the BMS. I know that Orion and some of those will do it, but they cost $400+.

Those two JK’s may or may not include the relay( likely not) since the current isn’t mentioned. I think they may actually have provisions for two external relay controls, charge and discharge. I’d seen a diagram somewhere and it made me wonder but didn’t dwell on it.

The 200A or 300A JBD model is a decent choice. I recommend changing the 4 gauge cable to something larger like 2/0 if you plan to actually pull high current through it.
