Multiplying Socket to allow parallel charging of 12V blocks

We have made a Multiplying Socket to allow to charge more 12V LP block from a high speed charger.

One charger can charge up to 3 blocks at one time.

Two new tools to monitor 12V batteries

Simple monitoring solutions for the 12V batteries:

BM1 - Battery Monitor - A simple solution to monitor 12V batteries. When the battery is getting low, the beep signal will sound. Works very well with LP 12V batteries.

APM1 - Battery Indicator - Check your battery voltage all the time. Can be used with the car 12V socket. Ideal to monitor the voltage of the 12V LP batteries or the battery packs.

Suggestions and Tips for these tools:

EV scooters: Use 4 pcs of BM1 to monitor each 12V LP battery in a 48V EV scooter. You get warning when one of the batteries gets weaker and the voltage drops down.

24V battery systems: Use 2 APM1 to check the voltage of each of the 12V battery bank. You can see if the voltage on both banks is the same during the load peaks.

The 12V battery protection circuit to disconnect high-currents

Using a high-power relay or contactor it is possible to protect the battery against deep discharge when draining high currents.

12V battery protection - Battery guard (accu saver) 12 V/DC [M148A]

Please see a useful link for a simple battery protection circuit. KEMO Battery guard (accu saver) 12 V/DC [M148A]. Please note this protection works up to 10A currents. It cannot be used for high-current solutions.

Note: based on KEMO specifications the peak voltage for M148A is max 15V. When you plan to use this device please do not charge above 15V.

LFP Cell Model Calculator

Are you designing a battery pack using LFP cells? Please check the LFP Cell Model Calculator to help you decide the number of cells and the capacity (size) of the cells in relation to the total power and the discharge model.
