"It works pretty good, it still slows down changes time but I guess I can’t complain it does it’s job in a very safe way."

The Lumenier ParaGuard PRO Parallel Charging Board offers the safest solution for parallel charging your LiPo batteries. Designed with multiple layers of protection, it ensures worry-free charging, giving you peace of mind with every connection. With advanced safety features and robust build quality, the ParaGuard PRO is your go-to choice for safe and efficient battery charging.
The ParaGuard PRO is a significant upgrade over the original version, featuring a sleek CNC-machined aluminum casing in an eye-catching black and silver finish. It also includes digital LED displays that show real-time voltage and amperage readouts, offering greater visibility into your charging process. Plus, the added dual USB ports provide even more charging flexibility, making the ParaGuard PRO the ultimate parallel charging board for your needs.
The ParaGuard PRO incorporates a series of protective features designed to prevent accidents and protect both your batteries and equipment:
Protects against different cell counts being plugged in together
If you accidentally connect batteries with different cell counts, like a 3S and 4S, the self-resetting fuse bus will trip, protecting both the board and batteries from a high surge during connection. You can simply correct the mistake and resume charging.
Prevents incorrect balance cable connections
If a balance cable is inserted incorrectly, a short circuit is prevented by the self-resetting fuse. Simply unplug and reconnect the cable properly, and charging can continue without issue.
Protects against power surges
In the event of a high current surge, such as during a battery failure, the self-resetting fuses will protect your equipment from damage. This feature also safeguards against accidental connections of batteries with different voltages (like a 2S and 3S together, although this should never be done intentionally).
Parallel charging safety should always be a priority. Never leave a charging battery unattended, and always double-check the cell voltages of your batteries before connecting them in parallel. Ensure that the voltage difference between batteries is no more than 0.1V for safe charging.
