Victron MPPT charge controllers are one of the best solar controllers for charging lithium and lead-acid batteries. In fact, they can be set manually to charge any battery chemistry. This and more info you can find while browsing through the guide.
For example, Victron MPPT 75/15 unit shown above can operate with 12,24 and 48V battery sets, whereas 100/20 and 100/30 models are only compatible with 12 and 24V battery banks. Make sure to verify the charge controller operation voltage before purchasing a controller. There are many other models available in the market, do not hesitate to contact us if you need help selecting the right one. In this manual, we want to show you how to program Victron MPPT charging settings for lithium-ion and lead-acid batteries.

The example below reflects a 12V battery bank scenario, for the 24 and 48V systems simply multiply the 12V values by 2 and 4 respectively.
