So, after waffling back and forth a couple of times, I choose to mostly use 4AWG cable that I can get for .50$/ft. The main reason for this instead of bus bars is because then everything can be easily insulated. It’s harder to insulation busbars. I will have a 4x4 battery bank of 50Ah...

So I replaced four of the BMS circuit boards in the liFePo4 Powersonic Batteries with Daley 4S 12V 30 Amp BMS modules, two dumb hardware BMS, and two Smart BMS modules. The Daley Smart BMS modules are twice as expensive, but they allow you to set various parameters, includes a temperature...

These batteries are on the small side, 50Ah, so I will have to hook a few of them up in parallel. The problem is that each battery has a BMS (which I may have to replace if I can’t the BMS working. Do I then need a master BMS to manage the whole bank. I tend to be frugal with power. An AC...

Substrate: you’re wrong on all counts. I’m doing this for my self. I like recycling old things. I like figuring out how things work. why shouldn’t I try to recycle some hospital grade LiFePo batteries?

There a a LOT of BMS on the site. I’m looking for a 12V 4S BMS. How many Amps would be appropriate for a Shuttle Bus RV? I’m not one to waste power profligately, but want plenty of headroom. Since X Amps at 12V = X/10 at 120V, that could be a LOT of amps! Somewhat scary…. 100 Amps is only...

The Valence Batteries seem to be workin well, but I only have four of them. I am hoping to add about a dozen PowerSonic PSL-12450 Batteries which look similar That I got from E-Scrap. The BMS on the PSL seem to be dead, but there is supposedly a way to revive a dead BMS? I have charged the...

What do the MOSFETs do? I have some Power Sonic PSL-12450 LiFePo4 batteries, where the BMS appears to be bad. The battery pack has voltage, but it stops at a bunch of large ganged up three lead components which I assume are the MOSFETs.

Can you use C- for more gradual charging systems like solar, and P- for faster charging like plug-in or high capacity alternators? My Shuttle Bus has two high capacity alternators.

I have four of these LiFePo4 Valence U1-12RT Batteries, I got from a friend who is an electronic scrap dealer. They Work Great. I can get a dozen similar Power Sonic Batteries, but their BMS may be bad. The battery pack reads ~14V, but the terminals don’t show any voltage. The voltage stops...

I am looking for Recommendations for a DC to DC and/or MPPT battery charger for a 2005 E450 Shuttlebus with two alternators. I have Four Valence U1-12RT LiFePh Batteries ATM and a Powermax 1000W Pure Sine Wave inverter. I want to charge from the alternator as much as possible, and add solar...
