0Ah to 100Ah Batteries

Compact Deep Cycle Batteries up to 100Ah for Caravans, 4WDs, Marine and Off-Grid

A battery of 100Ah or less gives you reliable energy storage where space, weight or budget is limited. This range includes 12V, 24V and 48V batteries in lithium (LiFePO4), AGM and gel. It suits a 4WD canopy fridge, a boat house bank, a camper trailer or a compact 48V energy storage system. Brands include Victron Energy, Enerdrive, Invicta, Century, Power-Sonic and Pylontech. Capacities run from small 14Ah and 20Ah units up to full 100Ah batteries.

Lithium 100Ah Batteries

A 100Ah lithium battery offers more usable capacity and lower weight than a lead-acid battery of the same rating. The Victron Smart LiFePO4 and Smart NG (NextGen) batteries come in 12V, 24V and 48V. They include Bluetooth monitoring and work with Victron system components.

Victron SuperPack and SuperPack NG batteries have an internal battery management system (BMS), which makes installation simpler. The Alpha IP67 Smart Bluetooth series covers 20Ah to 100Ah and includes a Slimline 100Ah model for tight compartments. The Enerdrive B-TEC Ultra IP67 is suited to wet or dusty locations. For stationary storage, the Pylontech US5000-B is a 48V 100Ah rack-mounted module.

Hybrid Lithium and Dual-Purpose Cranking Batteries

Some vehicles and boats need one battery that can start an engine and also run accessories. Invicta Hybrid lithium batteries are rated from 800CCA to 1400CCA and come in case sizes including LN2, LN3, 95D and H31H. Century Marine Pro batteries cover 65Ah to 100Ah at 580 to 1000 CCA. The Century Dual Force+ AGM provides 90Ah with 750 CCA.

100Ah AGM and Gel Deep Cycle Batteries

AGM batteries are maintenance-free and vibration resistant. They also cost less upfront, which suits backup power and builds with simple charging setups. Options include:

• Victron AGM Super Cycle batteries from 15Ah to 100Ah
• Victron standard AGM batteries
• Century AGM batteries at 55Ah and 75Ah
• Power-Sonic AGM batteries at 48Ah, 59Ah and 80Ah

For slow, deep discharge in remote solar or marine installations, the Victron 90Ah Gel and Century 37Ah and 70Ah Gel batteries are also available.

Sizing and Selection Tips

• Calculate daily usage: Add up your loads in amp-hours or watt-hours. Then allow for usable capacity. Lithium can be discharged further than AGM or gel, which are usually kept above roughly 50% to protect cycle life.
• Match system voltage: Choose 12V for most caravans and 4WDs. Choose 24V or 48V for trucks, larger boats and inverter-based off-grid systems, where lower current allows smaller cables.
• Check discharge ratings: Confirm that the battery's continuous discharge current suits your inverter or motor load.
• Confirm charging compatibility: Lithium batteries need chargers with a LiFePO4 profile.
• Measure the space: Check your battery bay dimensions, and confirm IP rating and temperature suitability before buying.
