Lithium battery and sergeant chargers

[Camper634]

Could anyone advise if the standard chargers fitted by Sargents in many of today’s vans is sufficient to fully charge a lithium battery please?If not what is recommended as a replacement?Thanks.

I'd speak to the battery supplier. Don't take this as gospel, but my understanding is that the correct battery/charger matching is vital with lithium, and incorrect charging can lead to explosion and/or fire.

I don’t know much about Sargent chargers but I would be surprised if the older ones charged lithium batteries properly. LiFePO4 leisure batteries are not prone to exploding or catching fire, they are not the same as the ones used in Samsung phones or Boeing airliners which have different chemicals in them.

The answer to your question is no.
The “return to bulk” voltage setting in lead acid chargers is normally 12.5-12.7v. This voltage for a lithium battery is way too low. ... A lead-acid charger that can be set to charge no higher than 14.6v can be used for regular charging and then MUST be disconnected after the battery is fully charged.Nov 29, 2017

There is a lot of misinformation about Li-ion batteries, mostly because there are several different types. The ones used in phones are very different from LiFePO4 leisure batteries which whilst not needing to be kept on charge once full, can tolerate a maintenance voltage. They all need a battery management system and that intervenes if necessary.

That's a good job as I have LiPO batteries which are kept safe when charging due to the possibility of fire and they are only small ( Drone Batteries)
