Lithium battery for gate motors

Is this another gimmick to part you from your hard earned money? Let’s dig a little deeper.

No documentation to support any claim whatsoever. Yes, these batteries are used everywhere but they all have operating conditions. These are way more dangerous than lead acid batteries. When used outside of conditions they do catch fire all on it’s own. FACT!

These Lithium batteries are expensive, to maintain the battery you will need a charger suited for the specific battery you have or planning to get.

Use it in your gate motor? I would not recommend it.

  1. Lets take the charging cycle of a normal Lithium-ion battery – 15.2 – 15.5 vdc. a Standard domestic sliding gate motor with SLA battery voltage is between 14.2 and 14.4. This is not sufficient for Lithium batteries
  2. Gate motor battery leads are equipped with 4-5mm terminal lugs – Lithium batteries need 10mm – big reason for that. 

In short Know your power storage needs – a very good expensive battery is just expensive if you have no idea how to keep it good. Take your time, do research, allot. And buy what you need – lithium batteries in gate motors will only perform better with the correct charging system.

Rather – replace your charging system to something that will charge your 7ah battery full in 2 to 3 hours

Can I charge my lithium battery with a lead acid charger?

Detailed answer: Lithium batteries are not like lead acid and not all battery chargers are the same. A 12v lithium battery fully charged to 100% will hold voltage around 13.3-13.4v. Its lead acid cousin will be approx 12.6-12.7v.

A lithium battery at 20% capacity will hold voltage around 13V, its lead acid cousin will be approx. 11.8v at the same capacity.

So if you use lead acid charger to charge your lithium battery, it may not be fully charged.

You can use a AC to DC lead acid charger powered from mains power, as charge efficiency and duration are less of a concern, it must not have automatic de-sulphation or equalization modes. If it does, do not use it as there is a high chance of damage to the cells or battery. This can have significant reduction in battery longevity. If it has a simple bulk/ absorption/ float charge profile, then it can be used to recharge the battery but must be disconnected once charged and not left in trickle charge/maintenance mode. It must also have a maximum output voltage of 13v-14.5V. When it comes to DC- DC chargers and solar controllers, you must change these to LiFePO4 specific models.
