Lithium Batteries

Another for EV power, have been using two of their 100Ah built up backs for several years and they still test higher than their rated Ah. These batteries have been charged on a mix of chargers, a DCDC unit with user settings, a projecta mains charger set mostly to power supply mode and occasionally to either Gel or AGM if I wish to bring the batteries upto fully charged. Solar is being done by a projecta solar charger set to gel.

As an experiment I have recently purchased a DCS drop in. This battery can supposedly withstand high under bonnet temperatures and is suitable for use winching. and can be charged directly off the alternator. So far it is performing well. Initial testing shows Ah as per the manufactures, which is a bonus as it appears from many discussions on various forums that a lot of other brands don't come close to their rated Ah. Due to price though most would not be purchasing one of these units

Will be interesting to see how it goes over the next few years.

HKB just curious as to how you test the Ah of your batteries. The methods I've seen are rather time-consuming.

Yes time consuming, I use a battery capacity discharge tester. Set discharge amps, stop voltage and let it run. If I want to plot it then I connected a wireless volt and amp meters and log it to a laptop.

folks have committed to a 200ah lithium from Ev power.
