Prices are single-unit prices on each maker's own site: Redodo on October 22, 2026 and LiTime on October 23, 2026. "Inverter it can carry" is the BMS current times the low battery voltage times 90% efficiency, before any other loads.
Batteries without self-heating must not be charged below 32°F. Some models stop charging on their own in the cold; check the product page for a low-temperature cutoff.
How to choose
- Size it. Daily watt-hours x days without charging, divided by 0.8. The planner does this and picks the cheapest combination for you.
- Check the current. Your inverter's full-load draw plus your 12 V loads must stay under the bank's total BMS rating.
- Think about winter. If the battery lives somewhere that drops below 32°F while you need to charge, go self-heating.
- Consider 24 V for a 3,000 W inverter or a very large bank. The Redodo 24V 200Ah gives 5,120 Wh with half the current of a 12 V bank.

Questions people ask
What is the best lithium battery for a van?
For most vans, the one with the lowest cost per usable watt-hour that covers two days of your use. When we checked in October 2026 that was the Redodo 12V 320Ah Mini Bluetooth at $659.99, or about 16.1 cents per watt-hour. If you camp below freezing, pick a self-heating battery or keep it inside the heated space.
Why does the BMS current matter?
The battery's management system cuts power if you draw more than its rating. A 100 A BMS at 12 V can supply roughly a 1,000 W inverter at full load (with the fridge and lights also running). For a 2,000 W inverter, you need about 200 A of BMS, from one big battery or two in parallel.
One big battery or several small ones?
One big battery is less wiring and usually less money per watt-hour. Two in parallel add up their BMS current and give you a spare if one fails. Use identical batteries of the same age, and equal-length cables to each.
Do I need Bluetooth on the battery?
It's handy for checking each battery's state, but a shunt-based battery monitor reads the whole bank more accurately and works with any battery.
