Just received my 100 amp unit last night and was pleasantly surprised when I saw on the instruction sheet that they will warranty the BMS for ANY reason even if it's due to something stupid that you did. Now that's customer service!

I don't know if anyone else is running this model (PIP-LV-MR 3K) but here is the manual as well. I just received mine and will be installing it in my Sprinter

Disregard, Google flipped the numbers on me and took me to the wrong charger. Thanks for the info BTW. I was looking for something to charge my 24V LiFePo4 battery bank from my 12V alternator in my Sprinter and didn't think it was possible without adding a second 24V unit.

1) These were clearly damaged before packing. 2) The shipping company isn't responsible for poor packaging and they will not cover this. 3) The seller has to file a claim, not the buyer. 4) The seller is the one obligated to make this right on their dime no matter what. I'm not paying to return...

I don't mind the 5 days of charging with a $60 10 amp charger, but I don't want to leave it unattended the whole time just in case the magic smoke appears while I'm at work.

That's the plan.

I asked the MPP reps about low temp cutoff on another model and their units do not support it. You're going to have to rely on the BMS for it.

The Overkill BMS already has built in cell monitoring. I know it only measures voltage but that doesn't really tell the SOC does it?

They want me to pay for return shipping to get a refund/replacement. When I first contacted them, they said it was no big deal and will not affect the performance of the cells. That's not the point. I didn't pay for damaged cells.

Charging my battery pack for the first time and the MPP Solar seems to only get to the float voltage setting and then stops charging. I have the Bulk charging set to 28V and the float set to 27.2V I have the BMS set to 80% duty cycle (Overkill Solar) and the cells are showing 3.4V which is 80%...

It is not my responsibility to contact the shipping company to file a claim, it is the seller's. A reputable seller would just ship new cells and file a claim with the shipping company and deal with them directly.

Well, I got it wired up and charging. Edit: I just read that the cells are now starting to balance.

Why are you worried about temps when it's no were near having any issues with your cells?

A shunt will read SOC from the whole pack.

None of those listed are 280 Ah

Just got (8) 280 Ah cells in yesterday and almost every cell reads 3.28 volts except for one that reads 3.32 volts. I want to connect them all in parallel to equalize the voltage across all cells and they did not come with enough bus bars to connect them all. I would like to use some 10-12...

Why do you need to buy a drill press? You can simply use a hand drill.

You got the best answer anyone could give (Helicoil). What else do you want, someone to hold your hand or do it for you?

Just going to let them sit for now. Still trying to decide on a BMS and I'm steering towards a Chargery unless there are better alternatives? 8s 24V configuration in conjunction with a 2700 watt pure sign wave inverter.

Would you guys hook up one of those $60 bench top power supplies and leave it unattended for days at a time? I'm in no hurry to top balance the pack, but (8) 280Ah cells is going to take a while and I work for a living.

What power supply are you using?

I have one as well at my shop. My point is, you can certainly make a nice set of buss bars with a simple hand drill.

Thanks for that Snoobler. I just got off the phone with Ian from Watts247 and he suggested to set the bulk and float charging volts to the same level. I will do this to fully charge the bank and do a capacity test and once complete, adjust both to where I would like to top off the battery to...

Sourced them through AliExpress. I'll get the vendors name once I get out of work and I'm home. I purchased an MPPT all in one unit that is 24V and has a built in charger, auto transfer to 110V when plugged in, solar charge controller and 2.7K watt inverter.

I've already read the guide and watched Will's videos before I posted here. I guess you guys are saying to top off the cells to about 3.5 volts with the MPP Solar charger and then top them off with the desktop power supply?

"My insulated garage where the batteries are located rarely drops below 37 degrees Fahrenheit and usually closer to 50 degrees."

I personally would use a grey/black tank heating pad set with a thermostat if that is the case.

I have a question for you guys. I just got my Overkill Solar 8s 24V BMS and want to bench test my setup before install. I had planned on putting a disconnect between the all in one unit and the BMS to be able to isolate if needed. Max draw would be about 125 amps, and I was wondering if a...
