Anybody know if it’s possible to convert my start and leisure batteries to lithium? Anyone done this? The advantages I guess would be weight saving and superior AH compared to traditional systems.
@Clive Neilands hope all is well with you and the family? Doesn't look like i'll be making it to Sweden this, fingers crossed for next year! All the best
Been drooling over those Corvus Energy marine battery packs ? The only worry I would have is on the equivalent CCA figures. If a car battery has a CCA rating of about 8C, a high discharge rate LiFeP04 is lower , more like 5 or 6C So you need 1.5 to 2x the capacity of the lead acid battery for a replacement LiFePO4 starter battery. Our 24 volt /100AH lithium batteries ( based on 18650 laptop style cells, same size casing as small truck batteries but much lighter) we use on a small boat for propulsion trip out at 100 amps: if you tried to start an engine you might need 3 or 4 batteries in parallel. Space may be a problem. Probably better going for something like the Rolls sealed lead acid starter or even a Bosch S4 wet lead acid which are very small just for starting and then your big 100-200AH lithium battery for everything else.... Or a bank of supercaps you charge up for starting. The little starter packs arent really designed for daiily thrashing..
