you lose 5% capacity. Actually not quite. On one side, capacity is coulombs, and exacltly the same total number of coulombs will flow out of the battery with or without the diode.. On the other side, the load may have a low-voltage cutout; if the cutout voltage is set so that it trips before the BMS does, then, yes, the cutout would trip a bit earlier, meaning that it uses less of the battery

What diode do I use when charging 2 batteries in parallel?
A diode will do it but has problems. The voltage drop means your gate battery will never charge full, and your application likely requires higher currents which tends to rules out Schotky diodes which have unusually low voltage drop (350 to 500 mV as opposed to 0.7 to 1.5 V) are difficult to find in large sizes.

The battery pack is connected through a BMS module. Both power supplies are connected to a switching circuit that ''selects'' the right source to use (DC if available, battery otherwise), using the LTC4416-1 chip. The DC input is also connected to a charging circuit using a DC-DC buck converter with CC/CV limiting to the BMS/battery pack. The problem

6 FAQs about [How to connect the diode to the battery pack]
Do you use diodes for 12V batteries?
I use 3 12V batteries wired in series for 36V, and use diodes to wire them in parallel for the 12V. The diodes stopping the batteries from shorting. I know diodes have a considerable voltage drop, and for the EV application I would use ideal diodes. By using the diodes, all batteries should drain equally, avoiding the battery pack unbalancing.
How does a battery diode work?
The diodes stop the batteries from shorting to each other, but they also deliver 36 V to your '12 V' output. If your low voltage drain is very, very small, say less than 1% of the drain on the whole pack, then you could maybe supply it from one battery, and rely on the charger to rebalance the cells when you recharge.
Why do EV batteries need diodes?
The diodes stopping the batteries from shorting. I know diodes have a considerable voltage drop, and for the EV application I would use ideal diodes. By using the diodes, all batteries should drain equally, avoiding the battery pack unbalancing. In the EV, the 12V batteries would be separate modules with their own monitoring. Is this a crazy idea?
How does a diode protect a battery?
A device that uses batteries will likely contain a diode that protects it when battery is inserted improperly. The diode will stop the reversed current from traveling from the battery to the rest of the circuit-- thus, the diode protects the sensitive electronics inside the your circuit.
How many diodes do I need for a 30amp BMS?
This model should be good for connecting 2 packs with a 30amp BMS, one diode per battery. This particular diode has 2internal diodes in them so to use it you need to solder the 2 outer leg together for the output and the middle leg is to connect to the positive of the battery.
What is a diode used for?
Diodes can be used in a number of ways, like to protect a current-sensitive circuit. A device that uses batteries will likely contain a diode that protects it when battery is inserted improperly.
