Frequently Asked Questions

Will these batteries work for my RV/van build-out?

They sure can! These 12V 100Ah batteries are designed for RVs and vans. Just double-check the dimensions to make certain they fit your compartment. Also, consider how many amp-hours you want for your planned electricity consumption.

What’s the lifespan of the LiFePO4 batteries compared to the AGM battery?

LiFePO4 (lithium iron phosphate) batteries generally last longer— often thousands of cycles—than AGM (absorbed glass mat) batteries. For example, some LiFePO4 batteries are good for 2000-15000 cycles, whereas AGM batteries typically offer hundreds of cycles. It depends on usage, but LiFePO4 gives you more bang for your buck over the long haul.

Can I use these batteries in cold weather? What about hot weather?

Some of these batteries (like the ECO-WORTHY and WEIZE) have built-in low-temperature protection that stops them from charging when it’s too cold. Others like the Renogy AGM perform well in extreme climates. Always check the battery specs to find ones designed for the temperatures you expect.

Do I need any special equipment to install or use these batteries?

For a simple swap, probably not. But if you’re setting up a system for the first time or connecting multiple batteries, it’s a good idea to get a compatible charger and possibly a battery monitor. Some batteries, need an specific RJ45 interface for bluetooth. Check the info about the products, and make sure to have all the tools to get the job done.

What happens if I’m not happy with the battery after I buy it?

Each brand has its own return policy, but usually, you can return a battery if it’s defective or doesn’t meet your needs. Look into the specific seller’s return for all the info before you buy.
