LeadAcid replace with Lifepo4 in campervan
This is usable for lead acid batteries but replacing the service battery with lithium may/will cause issues, there is nothing to limit the high current the lithium batteries may take, ( perhaps damaging the internal relay) the starter battery voltage may not be suitable, there is no termination of charge when the lithium battery is full.
Lithium‐based batteries, history, current status, challenges, and ...

EV Battery Charging Applications
The advent of Lithium battery-based vehicles led to battery voltages increasing to 400VDC or 800VDC,and even 1200VDC, to increase power whilst keeping weight as low as possible. (Higher voltages = lower current and therefore lighter conductors.) But, charging via a domestic AC socket to an onboard AC/DC charger is slow.
How Do You Charge A Lithium Battery With An Alternator?
Unlike traditional lead-acid batteries, lithium batteries require a specific charging profile, so you must use a battery charger that matches up well with lithium batteries. Additionally, you must ensure that the charging voltage and current are within the battery manufacturer''s recommended range and monitor the battery''s temperature …
Relay vs solenoid for dual battery
Hi. I am planning on adding a dual battery set up to my truck and I had a quick question. Everywhere I am looking at recommends a solenoid to isolate the batteries. I currently already have a 120 amp relay installed tied to the ignition because I wanted more acc electronics. Would the relay do...

relay
Relays that with the coil energized for months/years tend to breakdown (e.g. NC contacts tied to 12V+; goes high when coil is de-energized). Latching relays could be used but I''d need to turn a constant 48 V nominal into a momentary pulse (bosch style relay with R-C on contact path to-ground?), and do the same when 48 V is gone.
Relay-Type Catalysis by a Dual-Metal Single-Atom System in a Waste Biomass Derivative Host for High-Rate and Durable Li–S Batteries …
An environmental-friendly and sustainable carbon-based host is one of the most competitive strategies for achieving high loading and practicality of Li–S batteries. However, the polysulfide conversion reaction kinetics is still limited by the nonuniform or monofunctional catalyst configuration in the carbon host. In this work, we propose a …
