Battery run-time calculator for Li batteries

This is a simplified run-time calculator to estimate the run-time of your loads for Li batteries. You need to know: a. Battery capacity in mAh (mili Amp hours) b. Load currents in mA.

Please note 1Ah=1000mAh and 1A=1000mA. So if you have large car battery with 20Ah capacity, then put 20000  (mAh) as a number.

Wiring, installation and all about wires

This page will give you some basic knowledge about wires and also provide and few useful calculators for different electrical parameters, dependent on wire size. Please note: WE DO NOT SELL WIRES.

Connecting devises to solar panel

Some people treat solar panel as a battery with exact or close to exact voltage. Solar panels are made to specific applications with specific voltage parameters and wattage.

Charging SLA (Lead Acid battery) -basics

The lead acid chemistry is fairly tolerant of overcharging, which allows marketing organizations to get to extremely cheap chargers, even sealed lead acid batteries can recycle the gasses produced to prevent damage to the battery as long as the charge rate is slow. We offer a range of chargers from inexpensive to very sophisticated, depending on the requirements of the customer, but all of the chargers we sell off-the-shelf are highly regulated sophisticated chargers that cannot overcharge the battery.
