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.
If the voltage is below 2V, the internal structure of lithium battery will be damaged, and the battery life will be affected. 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.
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.
If lithium batteries have been deeply discharged they should be charged at a very low rate until they reach their minimum voltage above which they can accept the usualy high currents. So this sounds like a protection feature to me to prevent damage. ... but your batteries should never be seeing a low voltage disconnect event!
So in here in this post, we share with you some of the most commonly seen root causes to lithium-ion battery accident and their solutions. Hope our post help you with what you need. If the voltage is below 2V, the internal structure of lithium battery will be damaged, and the battery life will be affected.
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.
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. I …
