The AGM range has very low internal resistance making them particularly suitable for high current discharge applications such as for inverters, thrusters and winches.
VRLA AGM: design life 7-10 years
Features
VRLA technology
VRLA stands for Valve Regulated Lead Acid, which means that the batteries are sealed. Gas will escape through the safety valves only in case of overcharging or cell failure.
VRLA batteries are maintenance free for life.
Sealed (VRLA) AGM Batteries
AGM stands for Absorbent Glass Mat. In these batteries the electrolyte is absorbed into a glass-fibre mat between the plates by capillary action. As explained in our book ‘Energy Unlimited’, AGM batteries are more suitable for short-time delivery of high currents than gel batteries.
Low Self-Discharge
Because of the use of lead calcium grids and high purity materials, Victron VRLA batteries can be stored during long periods of time without recharge. The rate of self-discharge is less than 2% per month at 20°C. The self-discharge doubles for every increase in temperature by 10°C.
Victron VRLA batteries can therefore be stored for up to a year without recharging, if kept under cool conditions.
Exceptional Deep Discharge Recovery
Victron VRLA batteries have exceptional discharge recovery, even after deep or prolonged discharge.
Nevertheless repeatedly deep and prolonged discharge has a very negative effect on the service life of all lead acid batteries, Victron batteries are no exception.
Battery Discharging Characteristics
The rated capacity of Victron AGM and Gel Deep Cycle batteries refers to 20 hour discharge, in other words: a discharge current of 0,05 C. The rated capacity of Victron Tubular Plate Long Life batteries refers to 10 hours discharge. The effective capacity decreases with increasing discharge current (see table 1). Please note that the capacity reduction will be even faster in case of a constant power load, such as an inverter.
The AGM range has very low internal resistance making them particularly suitable for high current discharge applications such as for inverters, thrusters and winches.
VRLA AGM: design life 7-10 years
Features
A truly innovative battery
The AGM Super Cycle batteries are the result of recent battery electrochemistry developments.
The paste of the positive plates is less sensitive to softening, even in case of repeated 100% discharge of the battery, and new additives to the electrolyte reduce sulfation in case of deep discharge.
Exceptional 100% depth of discharge (DoD) performance
Tests have shown that the Super Cycle battery does withstand at least three hundred 100% DoD cycles.
The tests consist of a daily discharge to 10,8V with I = 0,2C20, followed by approximately two hours rest in discharged condition, and then a recharge with I = 0,2C20.
The two hours rest period in discharged condition will damage most batteries within 100 cycles, but not the Super Cycle battery.
We recommend the Super Cycle battery for applications where an occasional discharge to 100% DoD, or frequent discharge to 60- 80% DoD is expected.
Smaller and lighter
An additional advantage of the new chemistry is a slightly smaller size and less weight compared to our standard deep cycle AGM batteries.
Low internal resistance
The internal resistance is also slightly lower compared to our standard deep cycle AGM batteries
The BMV-700H is a high precision battery monitor. The essential function of a battery monitor is to calculate ampere hours consumed and the state of charge of a battery. Ampere hours consumed are calculated by integrating the current flowing in or out of the battery.
Features
Battery ‘fuel gauge’, time-to-go indicator, and much more
The remaining battery capacity depends on the ampere-hours consumed, discharge current, temperature and the age of the battery. Complex software algorithms are needed to take all these variables into account.
Next to the basic display options, such as voltage, current and ampere-hours consumed, the BMV-700 series also displays state of charge, time to go, and power consumption in Watts.
Easy to install
All electrical connections are to the quick connect PCB on the current shunt. The shunt connects to the monitor with a standard RJ12 telephone cable. Included: RJ 12 cable (10 m) and battery cable with fuse (2 m); no other components needed.
Also included are a separate front bezel for a square or round display appearance, a securing ring for the rear mounting and screws for the front mounting.
The BMV-710H Smart has Bluetooth built-in and can connect wirelessly to your phone (or tablet) via the VictronConnect App to conveniently read out all monitored battery parameters, like state of charge, time to go, historical information and much more.
The BMV-710H Smart is a high precision battery monitor that has been specially designed for systems with a high battery voltage ranging from 60 to 385 Volts.

Lithium-iron-phosphate (LiFePO4 or LFP) is the safest of the mainstream li-ion battery types. The nominal voltage of a LFP cell is 3,2V (lead-acid: 2V/cell). A 12,8V LFP battery therefore consists of 4 cells connected in series; and a 25,6V battery consists of 8 cells connected in series.
Features
Rugged
A lead-acid battery will fail prematurely due to sulfation:
A LFP battery does not need to be fully charged. Service life even slightly improves in case of partial charge instead of a full charge. This is a major advantage of LFP compared to lead-acid. Other advantages are the wide operating temperature range, excellent cycling performance, low internal resistance and high efficiency (see below).
LFP is therefore the chemistry of choice for demanding applications.
Efficient
In several applications (especially off-grid solar and/or wind), energy efficiency can be of crucial importance.
The round-trip energy efficiency (discharge from 100% to 0% and back to 100% charged) of the average leadacid battery is 80%.
The round-trip energy efficiency of a LFP battery is 92%.
The charge process of lead-acid batteries becomes particularly inefficient when the 80% state of charge has been reached, resulting in efficiencies of 50% or even less in solar systems where several days of reserve energy is required (battery operating in 70% to 100% charged state). In contrast, a LFP battery will still achieve 90% efficiency under shallow discharge conditions.
The remaining battery capacity depends on the ampere-hours consumed, discharge current, temperature and the age of the battery. Complex software algorithms are needed to take all these variables into account.
Next to the basic display options, such as voltage, current and ampere-hours consumed, the BMV-700 series also displays state of charge, time to go, and power consumption in Watts.
The BMV-702 features an additional input which can be programmed to measure the voltage (of a second battery), battery temperature or midpoint voltage (see below).

This feature, which is often used in industry to monitor large and expensive battery banks, is now for the first time made available at a low cost, to monitor any battery bank.
A battery bank consists of a string of series connected cells. The midpoint voltage is the voltage halfway along the string. Ideally, the midpoint voltage would be exactly half of the total voltage. In practice, however, deviations will be seen, that depend on many factors such as a different state of charge for new batteries or cells, different temperatures, internal leakage currents, capacities and much more.
Large or increasing deviation of the midpoint voltage, points to improper battery care or a failed battery or cell. Corrective action following a midpoint voltage alarm can prevent severe damage to an expensive battery. Please consult the BMV manual for more information.
