vmaxtanks v6 225 1VMAXTANKS 6 Volt 225Ah AGM Battery is one of the best buy deep cycle AGM batteries, suitable for use as solar or wind turbine battery, RV battery, golf cart battery, electric trolling battery etc. It features long Float Service Life (up to 8 to 10 years), but thanks to heavy duty lead tin alloy, it is very durable battery with long service life in either float or cyclic applications, even after repeated over discharges - which should be nonetheless avoided as much as possible, of course.

VMAXTANKS V6-225 battery nominal voltage is 6V - it consists of 3 cells, unlike most of the SLA AGM batteries which consists of 6 cells featuring 12V nominal voltage.

Since this is SLA AGM battery, it is practically maintenance free battery.

VMAXTANKS V6-225 battery 20h capacity is rated at 225 Ah - that means that this fully charged battery at 80°F (~25°C) can supply 11.25 Amps for 20 hours, without voltage falling below 10.5V.

Reserve capacity is rated at 500 minutes - that means that this, fully charged battery at 80°F (~25°C), can deliver 25Amps and maintain at least 10.5V of voltage for 500 minutes.

VMAXTANKS V6-225 battery weighs 72 pounds (~32.6 kg) and its physical dimensions are (W x D x H) 9.5 x 7.3 x 11 inches (~24.1 x 18.5 x 28 cm).

The closes BCI group is GC2, although one should check first if these batteries can fit in the desired space.

Recommended charging current is between 15 and 55 Amps, while recommended charging voltage is 7.2-7.35 volts. In float applications, float voltage should be kept between 6.6 V and 6.9 V.

These batteries should be charged using:

vmaxtanks bc1220a 1m- any quality smart microprocessor controlled AGM charger with the recommended specifications, like VMAXTANKS BC1215 and/or BC1220 (for 12V banks).

- solar panels and wind turbines in the 175W-450W range, although 120W panels and turbines may be used if depth of discharge is not below 50%.

Note: never use a battery charger with smaller amperage than the recommended. Also, battery maintainers should only be used to maintain a fully charged battery or battery pack but never as a battery charger. Charging the batteries with lower currents can shorten their operating life. Since good lead acid battery charger costs perhaps the half the price of one of these batteries, it is very smart investment.

Storage and discharge temperature range is between -4 and 140°F (-20 and 60°C) and charge temperature range is between 14 and 140°F (-10 and 60°C).

VMAXTANKS V6-225 Battery Packs

VMAXTANKS V6-225 can be connected in series and parallel to create battery packs of various voltages and capacities.

vmaxtanks v6 225 set

In golf cart and RV applications, 6 or 8 batteries can be connected in series to provide 36 or 48 V battery packs. Such 225 Ah battery pack can provide long operating range for golf carts on a single battery charge. In RV applications with 36 or 48V electrical systems, 225Ah house battery pack can power various appliances while being off the grid.

In marine applications, 4 batteries can be connected in parallel/series to form 12V 450 Ah battery or in series to form 24V 225 Ah battery. Such battery pack can power boat electrical systems for a really a long time, while being away from the harbor, without starting main engine(s) for charging the battery pack. Also, as the electric trolling motor battery, such battery pack can power, for example, Newport Vessels 86lb Thrust NV-Series (24V, 48 Amps max.) electric trolling motor for at least 4 hours at the full throttle.

In off-the-grid applications, 4 batteries can be connected to form 12V 450 Ah battery pack which can be charged combining solar panels, wind turbines and power generators using smart battery controller and which can be used for powering all desired appliances. Such new, fully charged battery pack can supply 270W for 20 hours continuously.

VMAXTANKS V6-225 Battery vs. VMAXTANKS MR197-200

VMAXTANKS MR197-200 is 12V 200Ah deep cycle AGM battery. Their main features are given in the following table:

Model Battery Type Goup Size Cell Type Ah MCA RC Weight (lbs/kg)
VMAXTANKS MR197-200 Deep Cycle 4D AGM 200 1400 560 112 lbs; 50.7 kg
VMAXTANKS V6-225 Deep Cycle GC2 (6 Volts) AGM 225 - 500 72 lbs, 32.6 kg

As one can see, VMAXTANKS MR197-200 is heavier unit, but again it is 12V battery, while VMAXTANKS V6-225 battery is 6V units.

When two VMAXTANKS V6-225 batteries are connected in series, they create 12V 225Ah battery pack, which is:

- heavier than single MR197-200 battery (144 pounds vs 112 pounds),

- has larger 20Ah capacity (225 Ah vs 200 Ah),

- has shorter RC rating (500 vs 560 minutes).

So, for applications where more power is required (~15 Amps or more), go for VMAXTANKS MR197-200 batteries and for applications where lower discharge currents are required (~15 Amps or less) for longer period of time, go for VMAXTANKS V6-225 batteries.

Obviously, if you are replacing GC2 batteries in your, for example RV vehicle, you have to go for the batteries that fits into the battery compartment.

Long Story Short: VMAXTANKS V6-225 battery is versatile and durable 6V 225 Ah battery. It can be used in 6V systems, but also it can form battery packs of various voltages and capacities. It is robust battery both internally and externally and it can withstand plenty of use and abuse - treat them carefully and they will serve you reliably for a long time.
