Ryobi OP4040 36V Batteries for Parts and Repair

Battery Hookup

Regular price $10.00

50 CENT SAMSUNG POWER CELLS ARE HERE! EVEN LESS WHEN YOU RECYCLE THE PCB, ALUMINUM, NICKEL, BRASS, AND COPPER! THE PLASTIC HOUSING WOULD MAKE A NICE LOAF OF BREAD HOLDER TOO!

EACH RYOBI OP4040 BATTERY HAS 20 SAMSUNG INR18650-20Q CELLS IN 10S2P CONFIGURATION. RYOBI CALLS THIS A 40V BATTERY FOR MARKETING REASONS BUT THESE ARE IN FACT 36V NOMINAL VOLTAGE BATTERY PACKS.

THESE NAME BRAND CELLS HAVE HIGH CYCLE LIFE AND CAN PUSH A TON OF POWER. PERFECT EBIKES, ESKATE, SCOOTERS, VAPE, POWERWALLS, ETC.

WE HAVE TESTED OVER 20,000 OF THESE CELLS FROM RYOBI PACKS. YOU CAN EXPECT TO REUSE THE VAST MAJORITY OF CELLS AND THEY TEST ON AVERAGE AROUND 90% CAPACITY. MOSTLY RANGING FROM 80-100% OF ORIGINAL CAPACITY.

ALL YOU NEED IS A T10 AND T8 SECURITY BIT TO REMOVE THE 6 SCREWS. THERE ARE 2 SCREWS HIDING UNDER THE STICKER ON THE TOP OF THE BATTERY CASE.

WE HAVE CUSTOMERS BUY THESE FROM US AND THEY SAY AROUND 40% OF THE BATTERIES THEY CAN GET TO WORK AGAIN AS IS TO USE WITH THEIR TOOLS BY SIMPLY CHARGING THE CELLS UP DIRECTLY. FOR US, THE REAL VALUE IS THE PRICE PER KILOWATT, SALVAGING THE NAME BRAND CELLS, AND TAKING THE SCRAP TO A JUNKYARD FOR MONEY WHICH MAKES THESE EVEN CHEAPER.

THESE BATTERIES TEND TO HAVE AN ISSUE WHERE THE BMS DRAINS THE CELLS LOWER THAN THE CHARGER CAN RECOGNIZE OR THE CHARGER AND BMS JUST DON'T COMMUNICATE. THAT RESULTS IN CELLS WITH VERY FEW CYCLES.

THESE ARE SOLD AS IS BUT WE HAVE BEEN ABLE TO REUSE AROUND 98-99% OF THE CELLS. 

WHILE THEY LAST, THESE ARE A GREAT VALUE AND THIS IS AN ITEM THAT REFURBISHERS TYPICALLY BUY IN BULK FOR REPAIR AND RESALE.

SPEC SHEETS FOR THE CELLS ARE BELOW.
