Zooms 12V 100Ah LiPO4 Battery Features and Specifications

Zooms 12V 100Ah LiPO4 battery features physical dimensions of (L x W x H) 13 x 6.82 x 8.48 inches (~33 x 17.3 x 21.5 cm) and it weighs only 25.35 pounds (~11.5 kg) - due to its dimensions, Zooms 12V 100Ah LiPO4 battery belongs to the BCI Group 31.

Internally, Zooms 12V 100Ah LiPO4 battery features 4S1P construction - it uses four 3.2V 100Ah cells to create a 12.8V 100Ah battery.

Also, it features a built-in Battery Management System (BMS) that protects the battery from unwanted events like overtemperature protection, overcurrent, and similar.

Zooms 12V 100Ah LiPO4 battery features a charging temperature range of 0°C to 50°C and discharging temperature range of -20°C to 60°C.

Maximum continuous charging/discharging current is set to 100 Amps, although personally, I would keep the maximum charging current up to 50 Amps. Just my 2c.

Since Zooms 12V 100Ah LiPO4 battery is a 12.8 volts battery and is able to provide at least 12V during most of the discharge cycle, the battery is able to provide at least 1200W during "almost" one hour.

We say "almost", but that is very close to exactly one hour, with some models providing even slightly more.

Note: when the battery is delivered, it features a 30-50% charge for safety reasons - before the very first use, check the documentation that comes with the battery and charge it fully using a lithium battery charger.

Zooms 12V 100Ah LiPO4 battery features IP65 dust/waterproof level, it is designed to be vibration resistant and can be mounted in any position.

Also, it is a spill-proof and maintenance-proof battery.

The battery features a 5-year warranty period and is able to withstand 2000-4000 charging/discharging cycles. Also, it features a very small self-discharge rate and practically no memory effect.

24v 400ah battery bank

Thanks to the built-in BMS, Zooms 12V 100Ah LiPO4 battery supports connecting in parallel (up to 4 batteries) and in series (up to 4 batteries), allowing the user to create battery banks of larger capacity and/or voltage.

Note: whenever connecting lithium batteries in parallel and/or series, always use the very same batteries of the same manufacturer, preferably from the same batch, and connect them as recommended.

For example, 8 (eight) Zooms 12V 100Ah LiPO4 batteries can be connected in 24V 400Ah battery bank that is able to provide 400 Amps @24V (actually @25.2V) for (almost) one hour - that is at least 9600W for (almost) one hour, making this battery suitable even for high power applications, including RV house battery, light industrial applications, off-the-grid applications and similar.

How To Charge Zooms 12V 100Ah LiPO4 Battery

Zooms 12V 100Ah LiPO4 battery can be recharged using solar panels, wind turbines, power generators, lithium battery chargers, lead-acid battery chargers with lithium battery charging modes, and similar.

It is important NOT to use advanced AGM/Gel-cell lead-acid battery chargers without dedicated lithium battery charging mode - if for some reason desulphation mode is triggered, it can even damage the BMS and hence the battery.

Charging voltage should be kept at 14.4V±0.2V - the battery should be charged using CC/CV (Constant Current/Constant Voltage) charging algorithm.

 With 100 Amps charging/discharging continuous current, Zooms 12V 100Ah battery can be recharged rather quickly.

However, in order not to stress the battery too much, if there is time, the battery can/should be recharged with 20-50 Amps lithium battery chargers.

For example, if the battery is discharged down to 50% DoD, 20 Amps lithium battery charger can fully recharge the battery in less than 3 hours.

For true off-the-grid applications, a solar charging controller combined with enough solar panels is recommended - for example, 6-8 100W solar panels may be connected to 50 or so Amps solar charging controller and can recharge Zooms 12V 100Ah battery discharged down to 100% DoD in ~2-3 hours, depending on the weather conditions, season, number of solar panels and similar.

Zooms 12V 100Ah LiPO4 Battery as Trolling Motor Battery

Zooms 12V 100Ah LiPO4 battery can be used as an excellent trolling motor battery for boats and kayaks.

For example, if the trolling motor draws 50 Amps, Zooms 12V 100Ah LiPO4 battery can power it up to 2 hours, which is a very good result for 25.35 pounds (11.5 kg) battery.

And since trolling motors are rarely used at full throttle, Zooms 12V 100Ah LiPO4 battery can power such trolling motor for a very long time.

Note: If the trolling motor is used most of the time at full throttle, that motor is seriously underpowered with practically no power remaining for emergencies.

Kayaks and smaller vessels can benefit even more when using Zooms 12V 100Ah LiFePO4 battery.

Kayak trolling motors rarely draw more than 30 Amps, and they use trolling motors mostly for quick hops from one location to another.

When the Zooms 12V 100Ah LiFePO4 battery is discharged at a rate of 30 Amps, it can operate for 3+ hours easily. Also, this allows the use of the battery for other purposes as well, like for powering navigation lights, fish finder, GPS, and similar electronics.
