Lithium marine batteries pros and cons

Is running a lithium battery down to zero a bad thing?

Running a lithium battery down to zero is also a bad thing. It’s not something you have to worry about as much now with today’s much more refined lithium marine batteries because the BMS sets a cutoff voltage and puts the battery to sleep (i.e. shuts down your system) to prevent it from ever getting too low.

What do Anglers know about lithium marine batteries?

The new generation of anglers, however, are coming up in the age of lithium marine batteries. Yet it’s somewhat telling how little most anglers know about lithium power. They have seen the literally “inflammatory” stories of the early days of lithium power in boats and have shied away from lithium power.

Is Lithium Power a good investment for a boat?

That next level of preemptive support is unheard of with battery power in boats. And Support is another huge piece to making sure the investment in lithium power is worth it. If you spend a lot of extra money on a large lithium battery, than you should reasonably expect a high level of support.

Can a Li-ion battery be connected to an outboard?

In the case of outboard-powered boats, the alternators and regulation systems are generally not compatible with li-ion recharge needs, so connecting the outboards to lead-acid batteries, then interconnecting li-ion batteries via DC-to-DC converters is a possible option. This will add considerable cost.

Is water bad for a lithium battery cell?

Water is maybe the worst thing for a lithium battery cell. The issue happens when charging a frozen or very cold battery causes the battery to warm up rapidly as it takes the charge from the charger. The rapid warm up of a cold battery causes it to build up condensation inside and that is the problem.

How much do Anglers know about lithium power?

Yet it’s somewhat telling how little most anglers know about lithium power. They have seen the literally “inflammatory” stories of the early days of lithium power in boats and have shied away from lithium power. Or they got lithium powered batteries but don’t understand the technology so they are not using it correctly or optimizing its longevity.
