Re: [Re-wrenches] 48v Lithium battery charger for unbricking single batteries

[Jay]

Iota and powermax will dead start.  Professionally investing in a eg4 charger or similar is a good idea.  Adjustable volt/amp setting. 120/240 input.  Jay On Oct 16, 2026, at 11:29 AM, John Blittersdorf <john.blittersd...@gmail.com> wrote:  Ditto on Meanwell power supplies.  I only had a 2 amp version but overnight it brought the EFlex up to 40 v so then put an iota 13 amp charger on it to bring it up to match the others.  I have used the Iota DLS 54-13 for rebooting and with a 2000 W or equivalent small generator, and charged an eVault and kept a rental ski house alive on a holiday weekend  with a Honda 2000 when their Kohler died. The renter was game for refueling the Honda when needed John Blittersdorf On Fri, Oct 16, 2026 at 12:28 PM Nick Lucchese <luccheseso...@gmail.com> wrote: Chris, I provide a Meanwell HLG-150H-54A for all of my systems that get a new 48v LiFePO4 battery. I sometimes hardwire it to the bus with a breaker clearly labeled and sometimes just provide it with some alligator clips. They've provided the expected result every time. They're very affordable and can be sourced affordably from Zonna as well as others. Seems like Fortress would have some options to recommend though for sure. Odd.

The battery voltage is 35. Thus I'll need to charge each one individually to bring them into the 49v range. So many options when it comes to chargers but I'd like to know what y'all are using with positive results. Fortress tech was unable to provide me with any options which I found odd.
