Self-heating uses incoming charger power
Renogy states that heating begins only when an external charger is connected, the battery is approximately 5–41°F, and charge current is greater than 4A. Heating stops when the battery reaches approximately 50°F.
Why this Renogy product
A smart legacy battery for monitored, low-temperature systems
Automatic cell warmingThe heating circuit raises cell temperature before charging in cold conditions instead of drawing from stored battery energy.
Integrated protectionRenogy lists a premium BMS, cell balancing and protection against common voltage, current and temperature faults.
Expandable in parallelRenogy allows up to eight matching batteries in parallel; this model is not approved for series connection.
System fit
Do not mix it with newer Renogy battery families or wire it in series.
Use a LiFePO4 charger whose voltage and current match the battery. Renogy limits continuous charge current to 50A and recommends batteries connected in parallel be the same brand, type, voltage, capacity and state of charge.
Parallel onlyRenogy permits up to eight matching RBT100LFP12SH batteries in parallel and does not approve series connection.
Optional monitoringA compatible BT-2 module connects to the UP communication port for DC Home app monitoring; the module is sold separately unless explicitly bundled.

Common questions
Buyer FAQ
Can I connect these batteries in series?
No. Renogy’s FAQ says this model may be connected only in parallel, with up to eight matching batteries.
Does self-heating use the battery’s stored energy?
No. Renogy states that the heating circuit uses power from the external charger.
Does it have built-in phone monitoring?
Not by itself. Renogy documents DC Home app communication through a compatible BT-2 module connected to the UP port.
Can I charge it below freezing?
Only through the documented self-heating process and within Renogy’s temperature and charger-current conditions. Never bypass the BMS or force charge a cold battery.
