Maximum Inverter Size
The Renogy 200ah lithium battery offers 200 amps of continuous discharge current per battery.
When you have multiple batteries wired in parallel, you can increase the discharge current for each battery in the bank.
The greater the maximum continuous discharge current, the greater the fully loaded inverter size the system can support.
- 1 x 200ah battery provides a maximum of 200a continuous discharge current. Multiply 200a by your system’s voltage (i.e., 12 volts), showing you can have a maximum inverter size of 2400w. Typically that will be a 2000w inverter.
- 2 x 200ah batteries provide a maximum of 400a continuous discharge current. Multiply 400a by your system’s voltage (i.e., 12 volts), showing you can have a maximum inverter size of 4800w. Typically that will be a 4000w inverter.
- And so on.
The important point to consider here is that just because the battery bank can support a fully loaded inverter of whatever size doesn’t mean you need to install one.
Renogy Lithium Battery vs. AGM Battery
Comparing a Renogy 200ah Lithium battery (100% usable capacity) with 4 x 200AH AGM battery (50% usable capacity):
|2 x 200Ah AGM||200Ah Lithium|
|Weight||255.8 lbs / 116 kg||60.2 lbs / 27.3 kg|
|Cost per cycle||$0.74||$0.50|
|Length*||20.6″ / 522 mm||20.55″ / 522 mm|
|Width*||8.8″ / 224 mm||8.62″ / 219 mm|
|Height*||9.4″ / 240 mm||9.45″ / 240 mm|
*Dimensions for the AGM batteries are per battery. The total space needed is their combined volume.
So to summarize, the Renogy 200ah Lithium battery, compared to 2 x 200ah Renogy AGM batteries, will:
- Last twice as long,
- Costs a third less upfront,
- Cost a third less over its lifetime,
- Weighs four times less, and
- Requires half the space.
Kind of a no-brainer, really.

Reliable BMS System
Every lithium battery needs a management system: a BMS. A few years ago, some lithium batteries needed a separate BMS. Today, most have an integrated BMS, so we don’t need to install another electrical component.
A BMS is the brain of the battery. It provides critical control over the battery to control charging rates and cell performance. It also provides safety protection features like
- short circuit,
- Over-temperature, and
- Voltage balancing features.
The BMS of each battery ensures its cells are balanced. This function performs just as well with multiple batteries wired in parallel.
This improves the average charging efficiency for your batteries in the long term.
Quick Charge Technology
One of the advantages of lithium batteries is they can absorb more electrical energy than the older AGM and Gels. They can absorb twice or even three times as much energy as an AGM equivalent.
The Renogy 200ah lithium battery can absorb over 50% of its capacity in an hour, significantly reducing the charging time.
Bluetooth & Real-time Monitor
Using the latest Bluetooth technology, you can monitor the battery operation status on mobile devices in real time.
It also uses a Zigbee communication protocol, which easily connects to Renogy’s latest power management system, the Renogy One.
If you’re after a reliable, name-brand lithium battery with a large capacity – and at an unbeatable price – there’s no better choice than this one.
Its low cost upfront makes it one of the most affordable options on the market today.
Renogy Support & Customer Care
There are mixed reviews on Renogy’s support. We’ve not needed to contact their support teams, so we don’t have first-hand experience to be able to comment.
And anyway, the Renogy batteries are considered reliable and stand up to the test of time. So, the likelihood of needing to contact their support teams is pretty low.
How Does The Renogy 200ah Lithium Battery Compare To Other Renogy Lithium Batteries?
Comparing a Renogy 200ah Lithium battery with a 2 x 100AH 12V 100Ah Smart Lithium Iron Phosphate Battery:
|200Ah Lithium||2 x 100Ah Lithium|
|Weight||60.2 lbs / 27.3 kg||52 lbs / 23.6 kg|
|Cost per cycle||$0.50||$0.35|
|Length||20.55″ / 522 mm||11.4″ / 289 mm|
|Width||8.62″ / 219 mm||6.8″ / 172 mm|
|Height||9.45″ / 240 mm||7.4″ / 188 mm|
So to summarize, the Renogy 200ah Lithium battery, compared to 2 x 100ah Renogy lithium batteries, is:
- 8lb heavier,
- Costs a third less upfront,
- Costs >40% more per cycle,
- Has half the lifespan, and
- Requires a little more space.
Those points make deciding between the two batteries more difficult than between the lithium and AGM.
There’s a little difference in the dimensions and the overall weight, but these are insignificant unless you have specific size constraints.
The cost per cycle is notably more expensive for the 200ah battery. However, the upfront cost is strikingly lower.
If you use one lifecycle per day, i.e., you’ve built no contingency into your battery bank, and you live in your van full-time, 2000 lifecycles will last five and half years.
In that time, the replacement costs of lithium batteries are likely to have fallen enormously. Five years ago, you’d have paid thousands for these batteries, and prices continue to fall.
Plus, in five years, you may have replaced your camper, motorhome or RV, in which case, you’ll be passing on the benefit of the longer lifecycle to the new buyer.
Overall, we believe the 200Ah lithium is a better buy than the 2 x 100Ah lithium batteries, but we’re splitting hairs, really.
So How Does The Renogy 200ah Lithium Battery Compare To The Competition?
|200Ah Renogy||2 x 100Ah Battle Born|
|Weight||60.2 lbs / 27.3 kg||62 lbs / 28.1 kg|
