Battery Buying Guide

While choosing a battery check these info to correctly match your requirements

Voltage

Must Match

New battery voltage must be the same as your old one.

Amp Hours

More is Longer

Higher Amp Hours give you longer runtime.
(Doesn’t affect power or speed).

Check Dimensions

Ensure the new battery fits your device.

FAQ Resource Hub
Which battery type is best for my application (golf cart, marine, RV, solar, mobility, industrial)?
The best battery depends on use: Lithium (LiFePO₄) offers longest cycle life (2,000–5,000 cycles), lightweight design, and high usable capacity, making it ideal for golf carts, RVs, marine, and solar. AGM/SLA are cost-effective, maintenance-free options for backup or starter needs, though cycle life is shorter. Flooded lead-acid works well for industrial or solar setups where maintenance is manageable. Always match voltage, dimensions, and charging compatibility to your system.
How long will my battery last?
Battery life means runtime (hours per charge) and lifespan (years/cycles). Runtime = (Voltage × Ah) ÷ Load. Example: a 48V 100Ah battery (4,800Wh) running a 1,000W motor lasts ~4.8 hours at 100% DoD. LiFePO₄ delivers 2,000–5,000 cycles; AGM/SLA typically 300–1,000. Calendar life averages 8–12 years for lithium and 3–7 for lead-acid.
How do I choose the right battery size?
Match voltage to system requirements (12V, 24V, 48V). Calculate daily energy use: load (W) × hours. Convert to Ah: Wh ÷ Voltage. Factor usable capacity: ~90% for lithium, ~50% for lead-acid. Add 10–20% margin for inefficiency.
Can I replace SLA/AGM with lithium?
Yes, but confirm compatibility. Voltage should match, and chargers must support LiFePO₄ profiles. Lithium needs a built-in BMS for protection. Ensure dimensions and terminals fit. Upgrading often gives double usable capacity, faster charging, and 3–5× cycle life.
