I can sum it up this way.. Does not work on boats, sail or power, and they are "generally rocking". Throwing a disc. would be about the only outcome.. Fight sulfation by using a proper absorption voltage. You don't need high current unless they are AGM..;)

Really depends when your bms initiates balancing.. If it only begis to balance at 3.5V then at 3.45 you're never balancing. I would just shorten absorption.....

Y?ou can buy it already cut to size at 18650 battery store and it's dirt cheap..

I ordered a JK BMS and it came with zero instructions? I emailed JK but they don't respond? All I need is 4S Does anyone have a diagram for 4S BMS balance wiring?

Trying to calculate the short circuit current of my cells? they are at 3.3V and the IR is 0.00032 Ohm. and I am running 2P4S is it 3.3V/ .00032=10,312A X2 = 20,624A

Just opened this up and the switch/display plug literally fell out from inside the BMS?Anyone else ever see this? It won't even boot up even with +/- 5-9V applied...

Yes I learned that the hard way. What a terrible company to try and deal with they do not answer phones.

Battleborn told me that.

That was one of the steps. I paid to have a Renology dc charger installed and it failed in four weeks.I suppose that is why my electrician had me sign a waiver that I was on my own for warranty? He said they were nothing but trouble and urged me to return it. Should have listened.

How doI limit the current?

I installed drop-in lifepo4 and the first failure they told me was bad diodes. paid for that repair and it happened again two weeks later. They finally sold me a brand new alternator. By week two that alternator basically caught on fire and the internals were totally melted.. They replaced it...

Firefly is no longer in business but they still hold the patent to carbon foam..
