questions Alan Hutty on 12/10/2021

What is your recommended size charger for this battery? Currently only have a Victron 5 Amp Smart Charger with a Lithium function. Optimate state that their LifePo4 5 Amp will charge batteries up to 100 Ahr capacity but initial feedback from Hubble states that one will need around 25 Amps to fully charge the S-100.


Hi Alan.  There is no minimum charge current, it will just take proportionally longer to charge them. i.e. if a 100A charge takes around an 1 hour to charge the battery, a 5A charger will take around 20 hours.
