So I just replaced my lead acid alarm battery with a BlueNova 13V 8Ah "alarm battery". The price was painful compared to what one usually pays for a lead acid, but we have had enough of the alarm system beeping a 2am in the morning waking everyone up due to bad battery, and with more blackouts probably on the way, I thought the BlueNova should last 3 times as long as they can supposedly drain right down to 5% and not have any affect on performance. Was it a good idea?

Thanks, will go with the Victron then, has all the bells and whistles and ease of use.

Quick question. If you had to choose between these two charge controllers, which would you take. Epsolar Xtra 3210N 30A 12-24V MPPT Charge Controller with LCD Display Victron SmartSolar 75V-15A MPPT Charge Controller

Would you know if this charge controller has the ability to change the settings for different types of batteries? How would one know this? https://www.sustainable.co.za/collections/mppt-charge-controllers/products/epsolar-xtra-3210n-30a-12-24v-mppt-charge-controller-with-lcd-display

Thanks very helpful, the parts I understand. Would it be advisable then for me to get a new charge controller?

Thanks, had to Google what BMS is..... It's a really old and cheap charge controller so not sure it can do that. A Steca Solsum 6.6F 6A as seen in the picture below. I have been looking, and for the price some other batteries can give you 3 times as many Ah compared to a Lifepo4. Dilemma. Question - does the Lifepo4 have the longest lifespan (I have read up to 15 years) of most batteries on the market?

So I have some odds and ends lying around from an old setup put together for charging AA, AAA batteries and walkie-talkies in the bush. Never got around to using it. Anyway, I want to use it now for the same including a laptop but just at home. So for a small setup like that would you choose a BlueNova or Freedom Won Lifepo4 battery? Also, the BlueNova is 13V, would that make a difference when connecting a NiteCore D4 battery charger to the Load connector of the Charge Controller Go easy on me, I'm new to this.
