Makspower MP 100 MK2 alternator is a prototype that charges extra high. It reaches close to 150 amps when it's cold. You'll see in the video that it's quite lively.
The original MP 100 alternator charges approx. 15 amps less but is still a very favorable alternator upgrade.
With good cables and the Makspower lithium battery bank, you can see that the alternator is powerful. Considering that the original Hitachi alternator rarely charged more than 40 amps, the MP 100 is a solid upgrade.
Makspower has very powerful alternators for Volvo engines. Read more about alternator upgrades at makspower.no

What does the charging curve show with voltage and amps?
In the video, you can see that there is some current flowing out of the battery bank and the voltage on the battery bank before the engine is started. Here's how you can keep an eye on the battery bank. Go to Trends in the app. Here you will see curves. Select which values you want to monitor. In this case, we have chosen V for volts and C for current.

The curves in the video show the relationship between voltage and amps going into the consumer bank.
It is a well-known myth that it should be charged at 14.4 volts. The curves in the video show that maximum charging occurs at low voltage. The voltage rises slowly as the lithium batteries fill up. The voltage rises slowly because the internal resistance of lithium batteries is very low compared to lead batteries.
That's why it's not possible to charge lead-acid batteries such as AGM and GEL nearly as fast.

Another great advantage of lithium batteries is that they can be completely drained without damage.

Recharging or topping up batteries can be done in no time at all, unlike lead-acid batteries that need to be topped up for hours.
