Why does my Lithium Battery voltage
Anyway, I tested the battery pack''s no-load voltage and the voltage at 48volt, 200-watt load, by putting a series of four 12v 50 watt bike lamps in series. Now the voltage dropped to zero
Reported battery charge drops suddenly from 50% to 7% :
The industrial convention requires a battery to hold 80% of original capacity after 500 (mobile device) or 1000 (laptop) cycles. Your situation is abnormal. A Lithium ion battery will degrade fast if: physically damaged, like falling or the battery tray is twisted in shape (that''s the real cause of Galaxy 7 incident). over heating
Battery voltage high & drops low under load!!
In your case, you have a very small battery (95Ah = ~47Ah usable) so the voltage will drop rapidly even under relatively low load, so this behavior is as expected.

Lithium battery SOC drop with peak solar?
Dan-norcal wrote: ↑ Mon Jun 17, 2024 8:24 pm After running this system for a few weeks, we have questions on the SOC of the EG4 battery and whether we should be concerned. The state of charge drops throughout the day from 100% to around 80% while the battery voltage stays at around 53.6. Towards the end of the day, the state of charge suddenly shoots up to 100%.
Battery voltage dropping quickly : r/SolarDIY
aha, yes the table shown there is as fair a rough-guess as may be possible but you can see the graph on the left is a little more accurate and shows why voltage is so hard to use for a guide with lithium. Ultimately adding a battery monitor like the Victron BMV-712 will count the amp-hours in and out for a much more accurate SOC.

Common Ebike Battery Problems and How To Fix
Another reason for a battery dying very quickly can be as simple as the state of the battery itself. A Lithium-Ion battery''s standard lifespan is about 2-3 years, varying from an estimated 300 to 700 charge cycles. Beyond this threshold,
Battery charge suddenly drops from about 25% to 6%
But discharging the battery from 85% (eventually somehow related to hibernate) can cause the batteries charge counter to drift off more and more over time. The result is a sudden drop of battery life at some point (in my case, at around 45% it suddenly drops tp 6%). The battery reports 85% way too early.
Battery voltage high & drops low under load!!
@Sampeett I agree that your battery resting voltage appears high; normal resting voltage of an AGM battery is typically around ~12.8v. I suggest reaching out to your battery manufacturer regarding this, or taking the battery and having it tested. Dropping under load, however, is exactly how it works... when you apply a load to a battery, the voltage will drop.

Battery Voltage Drop: Common Causes and Effective Solutions
Causes of Voltage Drops. Battery size, age, and temperature are critical elements. Often, corroded cables and terminals accompany a voltage decrease, worsening the issue. Engaging in regular maintenance, such as cleaning and replacing damaged cables, can help to mitigate these problems. CR2032 lithium-ion battery: multi-scenario
Sudden voltage drop while on inverter
Battery terminal voltage drops as current increases. 11.6 under load jumping to 12.6 means the battery bank is very small or no longer working properly. Measuring the voltage at the inverter input adds another possibility. The battery terminal voltage may be higher if there is a loose or corroded connector in between.

$begingroup$ @WhatRoughBeast that''s not really true of this type of lithium cell. While the voltage drops under load, the unloaded voltage is a rather useful indicator of the state of charge - not a linear one, but the slope is useful. Much of the usable life, especially in placing something into use is when it reads in the 4.2 down to 3.7

6 FAQs about [The lithium battery voltage suddenly drops fast]
Why is my lithium ion battery draining so fast?
Identifying common problems with lithium-ion batteries is key to preventing mishaps and ensuring your devices function efficiently. One frequent lithium-ion battery problem is rapid discharge. If you notice your device’s battery draining faster than usual, it might be due to a defective battery or an energy-hungry app.
What causes low voltage in a lithium battery?
Root cause 1: High self-discharge, which causes low voltage. Solution: Charge the bare lithium battery directly using the charger with over-voltage protection, but do not use universal charge. It could be quite dangerous. Root cause 2: Uneven current.
What happens if a lithium battery won't charge?
If the battery won’t activate and allow charge/discharge over 1A, severe overdischarge is likely. Self-discharge or parasitic loads can deplete cells below 10V. Use a lithium battery charger on activation or force charge mode to revive. The battery management system (BMS) cuts off discharge if the voltage drops too low, preventing cell damage.
Why is my lithium battery discharging so fast?
A lithium battery discharging quickly is usually an early indication of damage or faulty handling. This is why reading and following your manufacturer's instructions is crucial as soon as you get your battery pack.
What causes a lithium battery to fail?
Root cause 2: Too long storage time. Lithium batteries are stored for too long, resulting in excessive capacity loss, internal passivation, and increased internal resistance. Solution: It can be solved by charging and discharging activation. Root cause 3: Abnormal heat.
What are some common problems with lithium-ion batteries?
Common problems with lithium-ion batteries include rapid discharge, failure to charge, unexpected shutdowns, and battery drain in idle devices. These issues can relate to energy-demanding apps, damaged ports, or flawed batteries.
