Product Information:

Eco Tree 24V 150Ah Lithium (LiFePo) Battery

Perfect for 24V systems on Boats & Yachts, Caravans, Motorhomes & Conversions, including off-grid camping and renewable storage

 

25.6V | 150Ah | 3,840Wh

Weight: 30.5Kg

 

Terminal Icon

M8 Terminals with Bolts & Washers Included

Perfect drop-in replacement for lead-acid batteries with eyelet connections. Automotive round post adaptors available upon request. 

 

Capacity Icon

Lasts longer between charges & overall life

Compared to lead-acid, lithium batteries boast a huge energy capacity which means they last longer per charge, and can be cycled (how many times discharged & charged) up to x10 more than lead-acid batteries which makes them perfect for investing in today's energy hungry equipment, off-grid and renewable demands.

 

Super Light Image

Weighs 30.5Kg

Compared to two lead acid batteries (same physical size), that would weigh 94Kg.

To get the same capacity in lead acid, it'll be 125Kg and a physically larger battery. Eco Tree can achieve this amazing weight saving, and save on space.

 

Consistent PowerFull output, all the time

Eco Tree lithium will maintain a consistent voltage output until it gets to approximately 95% discharged. When running equipment, this results in a consistent and predictable behaviour with a flat discharge voltage, rather than a curve.

Eco Tree's leading BMS (Battery Management System) allows greater current throughput than its competitors which is why we're confident in recommending them as direct lead acid replacements in most cases.

This 24V 150Ah battery will max out at 150Amps consistent (i.e. running anything for more than 30 seconds) and can pulse up to 400Amps for anything less than 3 seconds - going over these thresholds will trigger the BMS to disconnect the internal cells to the external terminals - the battery will need to go on a charger (preferably a lithium charger) in order to reset.

 

Fast ChargeFully charged in as little as 3 hours

Eco Tree lithium can be charged at super high rates which unlocks the full potential of lithium batteries. When charged at their recommended rate, these batteries can go from 5% to 90% in less than 2 hours.

Eco Tree's BMS allows the use of 98% of all chargers on the market with a specific AGM/Gel mode/setting but we'd recommend taking a look below at our recommended charge rate - lithium's large capacity means that they can take a while to charge if the charger is small in output (1-5Amps). If you're not sure if your current equipment is suitable, please get in contact and we'd be happy to check.

For the full benefit of lithium, we'd recommend taking a look at a specific lithium charger. Lithium chargers aren't too different to normal ones, but do have a UVP mode (Under Voltage Protection) - this means that when the BMS has triggered and there's no voltage at the terminals, the charger can reset the BMS and allow the battery to be charged - other chargers without UVP modes will look for a voltage before starting their charge so may not be able to reset a triggered BMS.

 

Lithium Cost SavingsInvest in your battery future

Eco Tree's super long life and incredible cycle life means the overall cost over the battery's life is much cheaper than lead acid equivalents.

Because lithium can be discharged to 100% of their capacity (~90% with Gel, ~75% AGM & ~60% traditional flooded lead acid) and with their improved energy density, they can be cycled magnitudes more than lead acid. With average use (discharged each use to 50% between 20ºC - 25ºC), Eco Tree will produce ~5,000 cycles over its lifetime, which equates to around a decade under normal use. The most premium lead-acid gel batteries can achieve 500 cycles.

1 cycle = 1 discharge + 1 charge

5,000 cycles ÷ 365 days (discharged to 50% everyday) = 13 Years

Because of the above, Ecotree lithium is also a perfect addition to off-grid systems and renewables as the price per charge/price per kWh is drastically reduced.

 

Safe lithium

 Lithium Iron Phosphate (LiFePO4)

Eco Tree's LiFePO4 cells are inherently made to be safe; so much so that we consider them to be safer than lead-acid thanks to their BMS. They can be used in any orientation (e.g. on its side), although on its base will give the best performance.

They contain absolutely no acid, generate no gas emissions and are highly recyclable. Any sign of anything that could damage the battery, the BMS will protect itself by shutting off - simply connect to a charger to turn the BMS back on.

 

Heater Icon

Perfect Operating Conditions Every Time

This Eco Tree battery includes insulated heating elements around the internal temperature sensitive components which means it'll keep the battery in perfect operating conditions at all times; even in freezing temperatures.

Most lithium batteries can be discharged between -20ºC and 40ºC, but do not like to be charged at anything less than 5ºC - so much so, the BMS will not allow charge at 0ºC or less. The heater installed will target 5ºC minimum when charging.

The extra monitoring means a slightly higher self-discharge rate of 3.5% per month, rather than the standard 3%.

 

Saft Logo
