High-Power B3 LiPo Charger (20A): Fast Charging When Time Matters.
This charger is the high-power, 20-amp version of the popular B3 charger, delivering 1.6A per channel—nearly three times faster than our lower-amp option. It’s designed for builders who need to turn batteries around quickly between matches.
Most of the LiPo batteries we sell support fast charging:
Many are rated for 5C or higher
(Example: 5C × 300mAh = 1.5A)
Some support 15C or even 30C charge rates
A few batteries are limited to 2C
(Example: 0.6A max charge rate)
If fast charging is a priority and your batteries support higher C-rates, this charger is an excellent choice.
⚠️ Always verify your battery’s maximum charge rate before using high-output chargers. Best practice is to charge batteries inside a fire-retardant LiPo bag.
⚡ LiPo batteries must always be handled with care.
Even small LiPo packs store a significant amount of energy and require proper charging and supervision at all times.
If you’re looking for a smaller, budget-friendly, lower-risk option that charges at 0.6A, we recommend our 2S, 2 Port LiPo Charger instead.
