IMAX B3 10W Universal Charger for 7.4V Li-Pol, Li-Ion, Li-Fe Batteries

IMAX B3 10W Charger
The IMAX B3 10W charger by IMAX is an ideal choice for charging 2S Li-Po, Li-Ion and Li-Fe batteries. The “S” stands for the number of cells. It can also charge 3S (11.1V) batteries. This compact charger features LED indicators that show the status of the charge – red (charging) or green (charged). With a max charging current of 0.8 A, it is versatile and efficient for various battery types. In short, a charger that charges your batteries quickly, safely, and without unnecessary extra functions that most users never use. Charging is simple and safe, but we recommend charging and storing batteries only in protective pouches and bags.For safe battery handling beyond charging, read our guide: How to care for your batteries!

Warning
IMAX B3 10W is ideal for 7.4V batteries due to its lower charging output. It can also charge 11.1V (3S) batteries, but charging is slower, and some high-performance 11.1V batteries (Gens ACE LiHV or TITAN Li-Ion) require a higher charging current for optimal function and cell longevity. For long-term charging of powerful 11.1V batteries, we recommend the IMAX B3 20W model or more powerful chargers such as the Gens ACE G-Tech iMars S100 or iMars Mini 60W.
