[RE-wrenches] Lithium battery charge rate

Hi All I’m wondering if minimum charge amps for lithium is common or not? Or does it have to do with the cell shape: cylindrical vs prismatic vs pouch? A client purchased some EG4 batteries and they are getting a bit out of balanced. Tech support didn’t suggest higher volts or longer absorb but

Re: [RE-wrenches] Lithium battery charge rate

Hi Jay, For our LFMP and LFP batteries, it has never mattered. As long as current is flowing, the SoC is increasing and the voltage will rise until it reaches the CV set point. Typically cell balance occurs when a cell voltage reaches a set point where a load turns on across that cell. Ty

Re: [RE-wrenches] Lithium battery charge rate

Hi Jay, Larry says is correct. My experience, with cells and there BMS is they need to get up to top balance voltage then the BMS will stop charging the full cells and bring the remainder of cells up to fill charge. My oldest set is about 6 years old, since I understood they have been fine On Mo

[RE-wrenches] Remote load shedding

Hello Wrenches, Is anyone aware of a remote load shedding solution that doesn't require additional signal wiring to the loads? Generac has a great solution for this that they adapted from their generator business called a Generac Smart management module. Its a 2P x 50A relay that monitors line f

Re: [RE-wrenches] Remote load shedding

There are a couple of smart panel options available like Lumin and SPAN but may be more involved than what you are looking for -GlennSent from my 'smart'phone, so please excuse typos and spelling errors.-- Original message--From: Mac Lewis via RE-wrenchesDate: Tue, Jun 27, 2023 1:06 AMTo
