So you have purchased a 36-volt
lithium battery and are excited to use it. Maybe you have heard all the
good things about lithium batteries, such as reliability, durability, and a
longer lifespan. So it’s natural to think it will be better than standard
batteries. It will provide twice the power as three 12V lead-acid or AGM
batteries connected in a series, making it suitable for various applications,
such as trolling motors, forklifts, and golf carts. It charges faster, too, so
it reduces downtime and increases productivity.
But before proceeding, having the
proper charger is a must. Whether you choosing a lithium battery from the
get-go or are switching to it from a lead-acid battery. Here are the things you
should know about getting a battery charger for your 36-volt lithium battery.
Important: use a charger for lithium
batteries
Only use a charger meant for lithium
batteries. Lead-acid chargers won’t be suitable as they can reduce the capacity,
undercharge, and damage your battery over time. So, be sure to buy appropriate
chargers for your lithium-iron-phosphate batteries. Besides, lead-acid
batteries charge differently than lithium-ion-phosphate batteries in terms of
the rate of charge, which is higher for LiFePO4.
Things to expect when you get your
battery
The 36-volt lithium battery gets
checked before it leaves the factory and rechecked before it is shipped to you.
The lithium cells will balance the first several times you recharge the battery,
because they are new. Keep using the battery to help its cells balance.
Balancing the lithium cells lets you see less of a charge hours after it reads
100 percent, even if you haven’t used it yet. That is normal and should
dissipate after many complete cycles of battery use.
Match the charger to your battery
The charger should match the battery
you’re charging. It should deliver the correct voltage and current for the 36-volt lithium battery. For instance, you shouldn’t
charge a 36V battery with a 24V charger.
