Where It Fits
Common Questions
How is the LITE different from the ALPHA 2 and ALPHA 2 PRO?
All three share the same 12V 200Ah LiFePO4 chemistry. The LITE is the value-focused entry point in the lineup — the ALPHA 2 PRO adds Bluetooth monitoring, internal self-heating, and a higher 7,000+ cycle rating, which the LITE does not include.
What does “individually fused cells” mean?
Each lithium cell in the pack has its own fuse, so if a single cell develops a fault, it’s isolated rather than affecting the rest of the battery.
Does it have Bluetooth monitoring or self-heating?
No — those features are specific to the ALPHA 2 PRO. The ALPHA 2 LITE focuses on core reliability: a sophisticated BMS, individually fused cells, and IP55-rated protection.
Can the charging current change based on temperature?
Yes — maximum charging current varies by battery temperature, from 60A near freezing, up to 200A in the 68°F–104°F range, then back down to 60A above 104°F.
What’s the warranty on this battery?
Rich Solar’s product page for this battery doesn’t list a specific warranty term — check their warranty page or contact their support team directly for current coverage details.
