Here's a chart on what size solar panel you need to charge different capacity 24v lead-acid and Lithium (LiFePO4) batteries in 5 peak sun hoursusing an MPPT charge controller. .
Here's a chart about what size solar panel you need to charge a 24v 200ah lead-acid and lithium battery using an MPPT charge controller with different peak sun hours. .
In short, Yes, a 12v solar panel can charge a 24v battery. To get the maximum from a 12v solar panel to charge your 24v battery use an MPPT charge. .
Here's a chart about what size solar panel you need to charge a 24v 100ah lead-acid and lithium battery using an MPPT charge controller with different peak sun hours. For a 24 volt system the panel at max power rating needs to be 32 to 36 volts. Roughly 16 to 18 volts for every 12 volts of battery. However that rule only applies if you are using a standard PWM or shunt regulator. [pdf]

To understand how power tool batteries work, let’s take a look inside. A typical battery contains individual cells and a circuit board that work together to power your tools. .
Battery voltage plays a large role in how well your tool performs, but what exactly is voltage, and how is it calculated? .
Battery technology continues to evolve. As Eastman points out, even larger tools are migrating to battery power. The advertised battery voltage of 18V Lithium batteries is 18V or 20V. But a fully charged Lithium-Ion battery must be charged to 21 Volts before the battery indicator will show a 100% level. So, charge your battery at 20V to 21V volts if you want a full charge. [pdf]

In order to choose the best BMS for your lithium battery, you will need to know a little bit about the functions that a BMS provides. .
Lithium-ion batteries do not require a BMS to operate. With that being said, a lithium-ion battery pack should neverbe used without a BMS. The BMS is what prevents your battery cells from being drained or charged too much. Another important role of the BMS is to. .
Lithium-ion battery packs are composed of many lithium-ion cells in a complex series and parallel arrangement. Many cells are needed when. .
Well, that is actually a rather broad question with no single answer. When it comes to picking the best BMS, the brand is not super. .
When someone refers to the ‘size’ of a BMS, they are generally referring to the maximum amount of current the BMS can handle. You need to make sure to get a BMS that can support the amount of power that is required by your load. In fact, it's a good practice to add. [pdf]
