A fair point, but it raises another question for me. With lead-acid if your charger is too small it can lead to unequal cells. There’s some rule of thumb formula based on the 10 hour C-rate…..like 1/10th maybe? I’m not sure without looking it up. I’m not sure why. I imagine it’s like resist

I wouldn’t go so big with the charger/rectifier that you can’t run it off a portable generator if necessary, accounting for both load power and recharging the batteries. From: AF On Behalf Of TJ Trout Sent: Friday, April 5, 2024 3:25 PM To: AnimalFarm Microwave Users Group Subject: Re: [AFM

How much load? meanwell drs-480-48 are pretty good, if you need bigger than 10a/480w you can parallel or go to ICT or used eltek j series on ebay, which can be programmed for the correct voltage.. On Fri, Apr 5, 2024 at 1:13 PM Robert wrote: > LifePowers have a BMS. But most people power them

You will need a BMS unless the battery has one built in. If it does, a regular telco rectifier will do the job. -Original Message- From: Mark - Myakka Technologies via AF Sent: Friday, April 5, 2024 10:58 AM To: af@af.afmug.com Cc: Mark - Myakka Technologies Subject: [AFMUG] LiFePO4 q

I'm finding hard to pass up just getting a 100ah 48v LiFePO4 rackmount battery. I have a new fiber system that will need a maximum of 3kw once it is maxed out over the years. This seems like an easy and clean battery solution. Question is how do I power the system from the AC side on a daily b
