6 Frequently Asked Questions about “Lithium battery bypass”

What is a 12V lithium battery bypass switch?

The ITECHBYPASS Lithium battery bypass switch is used for bypassing the over discharge protection on a 12V lithium battery. All lithium batteries with over discharge protection will turn off (safe mode) when the voltage gets too low.

What is the itechbypass lithium battery bypass switch?

The iTECHBYPASS Lithium battery bypass switch is used when a Lithium battery is installed as a secondary battery. It bypasses the over discharge protection that most quality Lithium batteries have, which turns the battery off (safe mode) when the voltage gets too low.

Can I bulk charge a lithium battery without a BMS?

If you aren't balance charging every time though, you can bulk charge. Bulk charging is basically the same as charging a battery with a BMS, except that there is no BMS to watch the process. When lithium battery fires happen during charging, its usually because someone was bulk charging without a BMS and made a stupid mistake.

What is a BMS discharge bypass config?

The 2nd bms shows a bms discharge bypass config. The bypass makes this a charge only bms. From research online, this appears to be a fairly common practice in the e skate and other communities. The idea behind this is to bypass the discharge section of the bms to get full power from the battery.

Is it safe to bypass BMS discharge by soldering new wires?

bypassing the BMS discharge by soldering new wires onto the battery poles: is this safe? "ypassing the BMS discharge by soldering new wires onto the battery poles: is this safe" : specifically this is NOT safe, batteries are thermally sensitive.

Why do I need A BMS bypass?

The idea behind this is to bypass the discharge section of the bms to get full power from the battery. They can use a bms that has a lower amp rating but still get the higher amps desired because of the bms bypass wiring. Also an added benefit is the ability to avoid the bms shutting off power and thereby avoiding the not so pleasurable faceplant.
