Renogy 12V 200Ah Deep Cycle AGM Specs and Sizing
Researched from published standards and manufacturer specifications. Updated .
Quick answer
This is a specification sheet rather than a review. Every figure below comes from the manufacturer listing, and we do not test products in person. What this page adds is context: what these numbers mean for an RV system, and what else you need to buy alongside it.
Best for: A large lead-acid bank where weight is not a constraint.

What does this component need alongside it?
A battery is only as good as what charges it. A lithium pack needs a converter, solar controller and DC-DC charger that all carry a genuine lithium profile, plus a shunt monitor to read state of charge, correct cable sizing and a fuse at the positive terminal.

VMAX SLR100 12V 100Ah AGM Deep Cycle
$269.96A true deep cycle AGM with no cranking rating on the label, which is the fastest way to tell a house battery from a starting battery.
Best for: A lead-acid bank where lithium is out of budget.

UPLUS 12V 100Ah Deep Cycle AGM, Group 27
$189.99Sold as a leisure battery rather than a dual purpose one, so it is built for repeated discharge rather than engine starting.
Best for: The cheapest honest deep cycle option.

VMAX XTR27-110 12V 110Ah AGM Deep Cycle
$299.96The largest single AGM in this group at 110Ah, though it still gives less usable energy than a 100Ah lithium pack.
Best for: Squeezing the most out of one lead-acid case.

- What is the Renogy 12V 200Ah Deep Cycle AGM best for?
- A large lead-acid bank where weight is not a constraint. A 200Ah AGM weighs around 120 pounds and gives about 100Ah usable, which is the trade a lithium pack removes. Confirm the current specification on the listing before buying, because manufacturers revise these products without changing the model name.
- Is the Renogy 12V 200Ah Deep Cycle AGM suitable for a lithium system?
- Check the charge profile before pairing it with lithium. The requirement is a genuine LiFePO4 profile with the correct absorption voltage, not a lead-acid profile with a lithium label. Where a component only charges at lead-acid voltages, a lithium pack will sit permanently short of full.
- What size cable and fuse does it need?
- That depends on the current it carries and the length of the run, not on the component itself. Work out the current from its rating, then size the conductor for both ampacity and voltage drop with the wire gauge calculator, and fuse it at 125 percent of the continuous load rounded up to the next standard rating.
Lithium safety. A LiFePO4 bank needs a charger with a genuine lithium profile, and that means the converter, the solar controller and any DC-DC charger all have to be set correctly. A stock lead-acid converter will never bring a lithium pack to full. Charging a lithium battery below freezing damages the cells permanently, so the pack needs either a low temperature charge cutoff in its BMS or a self-heating design if you camp in the cold.
