RCGCBC 35Amp 12V/24V Battery Charger

The RCGCBC 35Amp battery charger is listed for 12V and 24V lithium, LiFePO4 and lead-acid batteries. Its LCD, automatic voltage detection and adjustable charging settings may suit owners maintaining batteries across vehicles, but its maximum-current claim should not be read as a fixed charging rate.

Pros and cons

Pros

Automatic 12V/24V detection and adjustable current settings offer flexibility across the listed battery types.
An LCD provides several charging parameters without relying only on status lights.
Alligator clips or ring terminals are listed as cable connection options.

Cons

It is not a jump starter and is not claimed to repair a completely lost battery.
Its 35 A figure is a maximum claim. The listing says the charger adjusts current automatically, so this is not a guaranteed rate for every battery.

What to know before buying

Listing details to confirm

Listing details conflict on dimensions: one entry gives 25.4D x 12.7W x 10.2H centimetres, while another gives 22.86 x 25.4 x 7.62 cm and a weight of 1.85 kg. Confirm the physical measurements before purchase. The title says 12V/24V, while the output-voltage field is malformed and specifies only 12 volts_of_direct_current, so 24V output is not confirmed by that field. The customer summary also refers to 20A output and adjustable speed, which conflicts with this listing's 35 A maximum claim. The listing says battery voltage must not be lower than 2.0V, says the charger cannot repair a completely lost battery, and requires a lithium battery to have a protection board (BMS). For batteries below 15AH, it advises using minimum current. Its special 24V recovery mode requires disconnecting power to deactivate it after 5 minutes.

Who is it for?

A good fit for

Owners charging listed 12V or 24V lithium, LiFePO4 or lead-acid batteries who want automatic voltage detection and adjustable current.
Drivers and owners of boats, RVs, golf carts, tractors or motorcycles seeking a charger that the listing says can also maintain batteries.
Buyers who want an LCD readout of charging conditions and percentage.

Less suited to

Anyone needing a jump starter or a claimed repair for a completely failed battery.
Anyone who needs a confirmed 24V output specification, a particular charging rate, or dimensions before purchase without resolving the listing inconsistencies.

Customer feedback describes the charger as easy to set up, compact and straightforward to use, with positive comments about its display, build quality, versatility and perceived charging speed. Those impressions may matter for routine charging and maintenance, where the LCD and automatic settings are relevant. However, the feedback summary refers to 20A output while this product listing claims a 35 A maximum, so it should not be used to confirm this model's output specification. Aggregate ratings lean positive but include lower-star ratings, and do not establish particular faults or explain why customers rated it as they did.

Positive themes

Customer feedback highlights ease of setup and use, compact size, display, build quality and versatility.

Frequently asked questions

Does this charger support 24V batteries?

The title and feature copy say 12V/24V and describe automatic voltage detection. However, the output-voltage field lists only a malformed 12-volt value, so confirm 24V support with the selected listing before buying.

Does it always charge at 35A?

No fixed rate is established. The listing calls 35 A the maximum and says current is adjusted automatically across three settings.

Can it jump-start a vehicle or revive a completely dead battery?

No. The listing says it is not a jump starter and cannot repair a completely lost battery. It also states a minimum battery voltage of 2.0V.

What should lithium-battery owners know?

The listing says lithium batteries must have a protection board (BMS). It advises minimum current for batteries below 15AH.
