SUNGOLDPOWER 12V 100Ah LiFePO4 Battery vs LiTime 12V 100Ah Group 24 LiFePO4

Both are 12V 100Ah LiFePO4 batteries from LiTime with a 100A BMS and roughly 4,000+ cycles. The Group 24 is smaller (10.23 x 6.61 x 8.22 in, 21 lb) and drops into a Group 24 box with no rewiring, which suits tight RV and camper bays. The Group 31 version adds Bluetooth monitoring, an LCD state-of-charge readout, self-heating below about 34°F and IP65 sealing, and it is the one to pick for cold-weather charging, marine use or anyone who wants to watch cell data from a phone. Owners rate the Group 24 well (4.8 from 50 ratings); the Group 31 trades a bigger footprint and more weight for those extras.

• Choose the LiTime 12V 100Ah Bluetooth/self-heating battery if you charge in near-freezing weather, mount it where it gets wet, or want Bluetooth and an LCD to track state of charge.
• Choose the LiTime 12V 100Ah Group 24 if your battery box or tray is sized for Group 24 and you want the smallest, lightest drop-in with no extra wiring.
