Lead Acid Battery Capacity Testing vs Lithium Battery Replacement for Caravans Boats & Off-Grid

Показать описание

Lead acid batteries have been around for a long time and they are cheap. The only thing is, are you really getting a decent battery and it is going to keep you powered up for as long as it says it will? Online Lead Acid batteries are getting so competitive that a 100Ah battery might only actually have around 60Ah capacity, and it might only last 6 months if deep cycling. Having said this, Lithium batteries are becoming much more affordable. a 100Ah lithium battery is half the weight and double the usable capacity compared to a lead acid battery. I can also last 20 to 50 times longer than a lead acid battery, so we feed the additional investment for a lithium LiFePO4 battery is now well worth it.
