The Go Power! 300Ah Advanced Lithium Battery (model GP-ADV-LIFEPO4-300) is a 12.8V, 300Ah (3,840Wh) lithium iron phosphate (LiFePO4) battery from the Sun Cycle Advanced line. It has a built-in battery management system (BMS), a DC heater for charging below freezing, Bluetooth monitoring through the Go Power! Connect app, and two RV-C ports for battery banks and the PowerTrak system.
Go Power built it for motorhomes, RVs, camping and marine use. One case replaces a bank of smaller batteries, delivers 200A continuous with a 400A surge, and carries a 10-year pro-rated warranty.
At 12.8V and 300Ah, the battery stores 3,840Wh. Go Power rates it for 3,000 cycles at 77°F (25°C). The case measures 19.6 x 14.9 x 8.11 in (498 x 379 x 206 mm) and weighs 70.5 lb (32 kg), with recessed handles for lifting.
Maximum continuous discharge is 200A with a 400A surge. The battery accepts up to 200A of charge current, and Go Power recommends 120A, so a large inverter charger or solar array can refill it quickly. Charge voltage is 14.2V, and the battery is fully charged at 14.6V.
A heater warms the cell module when the battery is charged in a freezing environment. Go Power rates charging from -4°F to 131°F (-20°C to 55°C). The heater turns on below 36°F (2°C) when a charging source is present and switches off above 45°F (7°C). In the app you can set the heater to Automatic, On or Off.
The Go Power! Connect app for iOS and Android shows voltage, state of charge, DC current, power, Ah remaining, charge state, time remaining and battery temperature. It also reports the charge cycle count and your deepest and average discharge, and it lets you switch the charge path or the whole DC source off and on.
Two RV-C ports, running at 250 kbps, link batteries to each other and to an RV-C network. Go Power says the battery shares its state of charge with the PowerTrak display, Dometic MPPT controllers and Go Power! inverters on that network.
The BMS protects against over- and under-voltage, over- and under-temperature, charge and discharge over-current and short circuits, and it balances cells automatically. A pre-charge circuit protects an inverter from inrush current at connection. The 300Ah case has a removable top lid for serviceability, handles that clip in place, integrated screw holes and optional brackets for wall mounting.
Residential fridge in an RV. Go Power estimates that one battery, with about 3,456Wh usable and 90% inverter efficiency, runs a 150W residential fridge through an inverter for about 23 hours.
12V living loads. On the same assumptions, Go Power estimates about 69 hours for a 50W average 12V compressor fridge and about 86 hours for a 40W CPAP without a humidifier.
Inverter-heavy coaches. The 200A continuous rating and 200A charge acceptance suit systems built around a large inverter charger.
Cold-season trips. The heater keeps solar and shore charging working when the battery is below freezing.
Go Power's comparison lists the 100Ah Advanced Lithium at 1,280Wh and 28.7 lb, and the 300Ah at 3,840Wh and 70.5 lb, both with 3,000 cycles and a 10-year pro-rated warranty. One 300Ah case gives you the same energy as three 100Ah batteries without the inter-battery data cables and interconnects a three-battery bank needs. The 100Ah fits smaller spaces and lets you add capacity a battery at a time.
In the same comparison, a pair of 6V 225Ah AGM batteries stores 2,700Wh with about 50% usable and weighs 70.5 lb each. The 300Ah Advanced Lithium stores 3,840Wh with close to all of it usable, weighs 70.5 lb in total, and adds Bluetooth, RV-C and self-heating.
Measure for 19.6 x 14.9 x 8.11 in and plan for a 70.5 lb lift. Go Power's installation guide shows the battery screwed down through its base, with optional L brackets to secure it against a wall. Go Power says a qualified electrician should connect the battery, and the full manual should be read before installing because wiring and configuration are required.
Connect up to eight batteries in parallel or up to four in series. Linked batteries need a data cable between each pair and a terminating resistor at each end of the bank; with a display connected, one end needs no resistor. Before linking, charge each battery fully and keep them within 1V of each other. Batteries ship in power-off mode: press the power button for 3 seconds to wake them, then configure them in the app. Go Power recommends ending discharge at 10V, and the case is rated IP67 but should not be submerged.
It accepts up to 200A of charge current, and Go Power recommends 120A. Charge voltage is 14.2V.
Yes. The built-in heater warms the cell module so the battery can charge down to -4°F (-20°C).
Go Power lists the 600 mm Advanced Lithium battery data cable (GP-ADV-BC-600) and the GP-RVC-BCR terminating resistor end cap as accessories for this battery.
Go Power covers the 300Ah Advanced Lithium Battery with a 10-year pro-rated warranty.
The Go Power! 300Ah Advanced Lithium Battery gives your 12V system 3,840Wh of LiFePO4 storage with self-heating, Bluetooth monitoring, RV-C communication and a 200A continuous rating. If you'd like help sizing your bank, choosing data cables or planning a PowerTrak setup, the Outbound Power team is happy to help.
