My Sargent EC155 isn't charging the Fogstar Lithium battery. I've checked the 15amp charger fuse on the Sargent and all the switches are up on the breaker. Read another post on here that says probably easier to install a direct charge solution as, the charger function of the Sargent is...

Hi all I've been running the Sargent EC155 for the last 5 years or so and it's done the job. I've just upgraded to a Lithium Fogstar battery from my lead acid LB and the Sargent now keeps alarming randomly for high voltage. I've not changed anything else and have read that the Sargent's don't...

Hi Newish to the forum (read loads) and had the van for a year or so now… Current leisure battery very smelly (rotten eggs) and not holding charge (drops to 11.4v within an hour of being charged) so assume it is knackered. Am planning to add solar in due course so thought I might as well...

Thanks CAB took me a while for the penny to drop that the Sargent not needed to charge, it’s an AGM at the moment, I don’t do much off-grid camping but when it needs replacing will go lithium.

the 100/75 mppt will be fine as its got a lithium profile. the sargent has a fixed voltage output for the LB,. . . so can be used in the meantime, but wouldnt fully charge a lithium. - recoemended to swap out for a decent EHU battery charger . . like a Victron or a CTEK battery charger. you...

What's your battery? Lithium? But yes, the Victron presumably is there to replace the Sargent mains charging facility. The Sargent therefore is now just for distribution of the 12 and 240v.

Hi, sorry to message again about similar issue I’ve read many articles and a lot of it goes over my head lol…..but I’m looking at getting Renogy - 12V 100Ah Lithium Ion Battery w/Bluetooth. Currently have Sargent EC160 power supply so will this be sufficient to charge the lithium battery as...

Adding some pictures of your existing setup will help people advise. LiFePo batteries are not drop in replacements, if you have fitted the lithium battery without changing anything else you should consider disconnecting it until you have the chargers sorted out. Lithium batteries should not be...

Lithium needs a different charging profile which I don't think your Sargent device can provide. Your solar controller needs to have a Lithium profile too. So no, you can't just swap the battery out. Show us some photos of what you have and you will get good advice here. Pete

To be fair to Sargent that's more of a causal relationship, nothing inherently wrong with the units. It's just they are the wrong solution for a lot of folks and they are now very dated in a world rapidly needing more from an electrical system. Should they ever produce one with native DC-DC...

Have you connected your Fogstar directly in place you used to have an AGM battery? If you don't have an existing DC-DC charger and haven't fitted one then you will be connecting your AGM van battery directly to your Lithium battery via the split charge relay in the Sargent - and that's a very...

Your Sargent charger is 'suitable for lead-acid' batteries, so not ideal for Lithium, same for the VSR.

You are on the 12v side. To do it on the 240v side you'd need to fit an additional RCD and ground effectively having 2 EHU systems - that's not worth the cost, hassle or space in the van. The Sargent type systems are pretty competent and compact 240v consumer units and 12v fuse/switch boxes -...

Curious why you are asking Renogy about a Fogstar battery and a Sargent charger? Do you have a typo? I've queried Fogstar in the past about the apparent statement that they support direct alternator charging and they were a bit vague about it. The risk of using normal lead acid chargers with...

Looking to change up to 105ah Lithium. Currently have a 2015 VanWorx conversion. Sargent PX300 3 stage intelligent charger(14.4v peak) Koshun 300 inverter VSR relay Would the upgraded DC-DC charger replace Sargent unit and VSR relay?

Hi, I have a fully converted van with a Sargent EC155 unit. I am wanting to leave that in place, but fit a new battery charger to cope with a new lithium battery. Has anyone done this? If so, any advice would be appreciated. Secondly, it looks like I will also have to replace my Sterling...

Currently replacing my AGM leisure battery with a lithium one (Foster drift). I have the Sargent PX300. I asked both Renogy and Fogstar whether the profile was OK for lithium and got different answers. Fogstar said it would be Ok as the voltages are within the spec for the battery, Renogy...

Yes it does but it's the SA model and it's not compatible with Lithium battery. The Sargent keeps alarming too (High voltage alarm)

No you'd need to disable the "charger" and add something like a Victron mains charger to supply 12v power on EHU and charge the battery. This is quite a common thread so have a search on "Sargent". However it's important before planning that to be sure why your current battery is in trouble. A...

Have you changed the CTEK to a lithium capable one? One option is to just do that and see if that's enough to support your needs. If you get enough from the DC-DC charger you can just leave the Sargent charger off (pull it's fuse) If you find that you spend a few days on EHU and don't do...
